+# Connection Cleanup Code Patterns
+
+## Pattern 1: Safe Connection Cleanup
+
+```typescript
+public initiateCleanupOnce(record: IConnectionRecord, reason: string = 'normal'): void {
+  // Prevent duplicate cleanup
+  if (record.incomingTerminationReason === null || 
+      record.incomingTerminationReason === undefined) {
+    record.incomingTerminationReason = reason;
+    this.incrementTerminationStat('incoming', reason);
+  }
+  
+  this.cleanupConnection(record, reason);
+}
+
+public cleanupConnection(record: IConnectionRecord, reason: string = 'normal'): void {
+  if (!record.connectionClosed) {
+    record.connectionClosed = true;
+    
+    // Remove from tracking immediately
+    this.connectionRecords.delete(record.id);
+    this.securityManager.removeConnectionByIP(record.remoteIP, record.id);
+    
+    // Clear timers
+    if (record.cleanupTimer) {
+      clearTimeout(record.cleanupTimer);
+      record.cleanupTimer = undefined;
+    }
+    
+    // Clean up sockets
+    this.cleanupSocket(record, 'incoming', record.incoming);
+    if (record.outgoing) {
+      this.cleanupSocket(record, 'outgoing', record.outgoing);
+    }
+    
+    // Clear memory
+    record.pendingData = [];
+    record.pendingDataSize = 0;
+  }
+}
+```
+
+## Pattern 2: Socket Cleanup with Retry
+
+```typescript
+private cleanupSocket(
+  record: IConnectionRecord, 
+  side: 'incoming' | 'outgoing', 
+  socket: plugins.net.Socket
+): void {
+  try {
+    if (!socket.destroyed) {
+      // Graceful shutdown first
+      socket.end();
+      
+      // Force destroy after timeout
+      const socketTimeout = setTimeout(() => {
+        try {
+          if (!socket.destroyed) {
+            socket.destroy();
+          }
+        } catch (err) {
+          console.log(`[${record.id}] Error destroying ${side} socket: ${err}`);
+        }
+      }, 1000);
+      
+      // Don't block process exit
+      if (socketTimeout.unref) {
+        socketTimeout.unref();
+      }
+    }
+  } catch (err) {
+    console.log(`[${record.id}] Error closing ${side} socket: ${err}`);
+    // Fallback to destroy
+    try {
+      if (!socket.destroyed) {
+        socket.destroy();
+      }
+    } catch (destroyErr) {
+      console.log(`[${record.id}] Error destroying ${side} socket: ${destroyErr}`);
+    }
+  }
+}
+```
+
+## Pattern 3: NetworkProxy Bridge Cleanup
+
+```typescript
+public async forwardToNetworkProxy(
+  connectionId: string,
+  socket: plugins.net.Socket,
+  record: IConnectionRecord,
+  initialChunk: Buffer,
+  networkProxyPort: number,
+  cleanupCallback: (reason: string) => void
+): Promise<void> {
+  const proxySocket = new plugins.net.Socket();
+  
+  // Connect to NetworkProxy
+  await new Promise<void>((resolve, reject) => {
+    proxySocket.connect(networkProxyPort, 'localhost', () => {
+      resolve();
+    });
+    proxySocket.on('error', reject);
+  });
+  
+  // Send initial data
+  if (initialChunk) {
+    proxySocket.write(initialChunk);
+  }
+  
+  // Setup bidirectional piping
+  socket.pipe(proxySocket);
+  proxySocket.pipe(socket);
+  
+  // Comprehensive cleanup handler
+  const cleanup = (reason: string) => {
+    // Unpipe to prevent data loss
+    socket.unpipe(proxySocket);
+    proxySocket.unpipe(socket);
+    
+    // Destroy proxy socket
+    proxySocket.destroy();
+    
+    // Notify SmartProxy
+    cleanupCallback(reason);
+  };
+  
+  // Setup all cleanup triggers
+  socket.on('end', () => cleanup('socket_end'));
+  socket.on('error', () => cleanup('socket_error'));
+  proxySocket.on('end', () => cleanup('proxy_end'));  
+  proxySocket.on('error', () => cleanup('proxy_error'));
+}
+```
+
+## Pattern 4: Error Handler with Cleanup
+
+```typescript
+public handleError(side: 'incoming' | 'outgoing', record: IConnectionRecord) {
+  return (err: Error) => {
+    const code = (err as any).code;
+    let reason = 'error';
+    
+    // Map error codes to reasons
+    switch (code) {
+      case 'ECONNRESET':
+        reason = 'econnreset';
+        break;
+      case 'ETIMEDOUT':
+        reason = 'etimedout';
+        break;
+      case 'ECONNREFUSED':
+        reason = 'connection_refused';
+        break;
+      case 'EHOSTUNREACH':
+        reason = 'host_unreachable';
+        break;
+    }
+    
+    // Log with context
+    const duration = Date.now() - record.incomingStartTime;
+    console.log(
+      `[${record.id}] ${code} on ${side} side from ${record.remoteIP}. ` +
+      `Duration: ${plugins.prettyMs(duration)}`
+    );
+    
+    // Track termination reason
+    if (side === 'incoming' && record.incomingTerminationReason === null) {
+      record.incomingTerminationReason = reason;
+      this.incrementTerminationStat('incoming', reason);
+    }
+    
+    // Initiate cleanup
+    this.initiateCleanupOnce(record, reason);
+  };
+}
+```
+
+## Pattern 5: Inactivity Check with Cleanup
+
+```typescript
+public performInactivityCheck(): void {
+  const now = Date.now();
+  const connectionIds = [...this.connectionRecords.keys()];
+  
+  for (const id of connectionIds) {
+    const record = this.connectionRecords.get(id);
+    if (!record) continue;
+    
+    // Skip if disabled or immortal
+    if (this.settings.disableInactivityCheck ||
+        (record.hasKeepAlive && this.settings.keepAliveTreatment === 'immortal')) {
+      continue;
+    }
+    
+    const inactivityTime = now - record.lastActivity;
+    let effectiveTimeout = this.settings.inactivityTimeout!;
+    
+    // Extended timeout for keep-alive
+    if (record.hasKeepAlive && this.settings.keepAliveTreatment === 'extended') {
+      effectiveTimeout *= (this.settings.keepAliveInactivityMultiplier || 6);
+    }
+    
+    if (inactivityTime > effectiveTimeout && !record.connectionClosed) {
+      // Warn before closing keep-alive connections
+      if (record.hasKeepAlive && !record.inactivityWarningIssued) {
+        console.log(`[${id}] Warning: Keep-alive connection inactive`);
+        record.inactivityWarningIssued = true;
+        // Grace period
+        record.lastActivity = now - (effectiveTimeout - 600000);
+      } else {
+        // Close the connection
+        console.log(`[${id}] Closing due to inactivity`);
+        this.cleanupConnection(record, 'inactivity');
+      }
+    }
+  }
+}
+```
+
+## Pattern 6: Complete Shutdown
+
+```typescript
+public clearConnections(): void {
+  const connectionIds = [...this.connectionRecords.keys()];
+  
+  // Phase 1: Graceful end
+  for (const id of connectionIds) {
+    const record = this.connectionRecords.get(id);
+    if (record) {
+      try {
+        // Clear timers
+        if (record.cleanupTimer) {
+          clearTimeout(record.cleanupTimer);
+          record.cleanupTimer = undefined;
+        }
+        
+        // Graceful socket end
+        if (record.incoming && !record.incoming.destroyed) {
+          record.incoming.end();
+        }
+        if (record.outgoing && !record.outgoing.destroyed) {
+          record.outgoing.end();
+        }
+      } catch (err) {
+        console.log(`Error during graceful end: ${err}`);
+      }
+    }
+  }
+  
+  // Phase 2: Force destroy after delay
+  setTimeout(() => {
+    for (const id of connectionIds) {
+      const record = this.connectionRecords.get(id);
+      if (record) {
+        try {
+          // Remove all listeners
+          if (record.incoming) {
+            record.incoming.removeAllListeners();
+            if (!record.incoming.destroyed) {
+              record.incoming.destroy();
+            }
+          }
+          if (record.outgoing) {
+            record.outgoing.removeAllListeners();
+            if (!record.outgoing.destroyed) {
+              record.outgoing.destroy();
+            }
+          }
+        } catch (err) {
+          console.log(`Error during forced destruction: ${err}`);
+        }
+      }
+    }
+    
+    // Clear all tracking
+    this.connectionRecords.clear();
+    this.terminationStats = { incoming: {}, outgoing: {} };
+  }, 100);
+}
+```
+
+## Pattern 7: Safe Event Handler Removal
+
+```typescript
+// Store handlers for later removal
+record.renegotiationHandler = this.tlsManager.createRenegotiationHandler(
+  connectionId,
+  serverName,
+  connInfo,
+  (connectionId, reason) => this.connectionManager.initiateCleanupOnce(record, reason)
+);
+
+// Add the handler
+socket.on('data', record.renegotiationHandler);
+
+// Remove during cleanup
+if (record.incoming) {
+  try {
+    record.incoming.removeAllListeners('data');
+    record.renegotiationHandler = undefined;
+  } catch (err) {
+    console.log(`[${record.id}] Error removing data handlers: ${err}`);
+  }
+}
+```
+
+## Pattern 8: Connection State Tracking
+
+```typescript
+interface IConnectionRecord {
+  id: string;
+  connectionClosed: boolean;
+  incomingTerminationReason: string | null;
+  outgoingTerminationReason: string | null;
+  cleanupTimer?: NodeJS.Timeout;
+  renegotiationHandler?: Function;
+  // ... other fields
+}
+
+// Check state before operations
+if (!record.connectionClosed) {
+  // Safe to perform operations
+}
+
+// Track cleanup state
+record.connectionClosed = true;
+```
+
+## Key Principles
+
+1. **Idempotency**: Cleanup operations should be safe to call multiple times
+2. **State Tracking**: Always track connection and cleanup state
+3. **Error Resilience**: Handle errors during cleanup gracefully
+4. **Resource Release**: Clear all references (timers, handlers, buffers)
+5. **Graceful First**: Try graceful shutdown before forced destroy
+6. **Comprehensive Coverage**: Handle all possible termination scenarios
+7. **Logging**: Track termination reasons for debugging
+8. **Memory Safety**: Clear data structures to prevent leaks

+# Connection Termination Issues and Solutions in SmartProxy/NetworkProxy
+
+## Common Connection Termination Scenarios
+
+### 1. Normal Connection Closure
+
+**Flow**:
+- Client or server initiates graceful close
+- 'close' event triggers cleanup
+- Connection removed from tracking
+- Resources freed
+
+**Code Path**:
+```typescript
+// In ConnectionManager
+handleClose(side: 'incoming' | 'outgoing', record: IConnectionRecord) {
+  record.incomingTerminationReason = 'normal';
+  this.initiateCleanupOnce(record, 'closed_' + side);
+}
+```
+
+### 2. Error-Based Termination
+
+**Common Errors**:
+- ECONNRESET: Connection reset by peer
+- ETIMEDOUT: Connection timed out
+- ECONNREFUSED: Connection refused
+- EHOSTUNREACH: Host unreachable
+
+**Handling**:
+```typescript
+handleError(side: 'incoming' | 'outgoing', record: IConnectionRecord) {
+  return (err: Error) => {
+    const code = (err as any).code;
+    let reason = 'error';
+    
+    if (code === 'ECONNRESET') {
+      reason = 'econnreset';
+    } else if (code === 'ETIMEDOUT') {
+      reason = 'etimedout';
+    }
+    
+    this.initiateCleanupOnce(record, reason);
+  };
+}
+```
+
+### 3. Inactivity Timeout
+
+**Detection**:
+```typescript
+performInactivityCheck(): void {
+  const now = Date.now();
+  for (const record of this.connectionRecords.values()) {
+    const inactivityTime = now - record.lastActivity;
+    if (inactivityTime > effectiveTimeout) {
+      this.cleanupConnection(record, 'inactivity');
+    }
+  }
+}
+```
+
+**Special Cases**:
+- Keep-alive connections get extended timeouts
+- "Immortal" connections bypass inactivity checks
+- Warning issued before closure for keep-alive connections
+
+### 4. NFTables-Handled Connections
+
+**Special Handling**:
+```typescript
+if (route.action.forwardingEngine === 'nftables') {
+  socket.end();
+  record.nftablesHandled = true;
+  this.connectionManager.initiateCleanupOnce(record, 'nftables_handled');
+  return;
+}
+```
+
+These connections are:
+- Handled at kernel level
+- Closed immediately at application level
+- Tracked for metrics only
+
+### 5. NetworkProxy Bridge Termination
+
+**Bridge Cleanup**:
+```typescript
+const cleanup = (reason: string) => {
+  socket.unpipe(proxySocket);
+  proxySocket.unpipe(socket);
+  proxySocket.destroy();
+  cleanupCallback(reason);
+};
+
+socket.on('end', () => cleanup('socket_end'));
+socket.on('error', () => cleanup('socket_error'));
+proxySocket.on('end', () => cleanup('proxy_end'));
+proxySocket.on('error', () => cleanup('proxy_error'));
+```
+
+## Preventing Connection Leaks
+
+### 1. Always Remove Event Listeners
+
+```typescript
+cleanupConnection(record: IConnectionRecord, reason: string): void {
+  if (record.incoming) {
+    record.incoming.removeAllListeners('data');
+    record.renegotiationHandler = undefined;
+  }
+}
+```
+
+### 2. Clear Timers
+
+```typescript
+if (record.cleanupTimer) {
+  clearTimeout(record.cleanupTimer);
+  record.cleanupTimer = undefined;
+}
+```
+
+### 3. Proper Socket Cleanup
+
+```typescript
+private cleanupSocket(record: IConnectionRecord, side: string, socket: net.Socket): void {
+  try {
+    if (!socket.destroyed) {
+      socket.end(); // Graceful
+      setTimeout(() => {
+        if (!socket.destroyed) {
+          socket.destroy(); // Forced
+        }
+      }, 1000);
+    }
+  } catch (err) {
+    console.log(`Error closing ${side} socket: ${err}`);
+  }
+}
+```
+
+### 4. Connection Record Cleanup
+
+```typescript
+// Clear pending data to prevent memory leaks
+record.pendingData = [];
+record.pendingDataSize = 0;
+
+// Remove from tracking map
+this.connectionRecords.delete(record.id);
+```
+
+## Monitoring and Debugging
+
+### 1. Termination Statistics
+
+```typescript
+private terminationStats: {
+  incoming: Record<string, number>;
+  outgoing: Record<string, number>;
+} = { incoming: {}, outgoing: {} };
+
+incrementTerminationStat(side: 'incoming' | 'outgoing', reason: string): void {
+  this.terminationStats[side][reason] = (this.terminationStats[side][reason] || 0) + 1;
+}
+```
+
+### 2. Connection Logging
+
+**Detailed Logging**:
+```typescript
+console.log(
+  `[${record.id}] Connection from ${record.remoteIP} terminated (${reason}).` +
+  ` Duration: ${prettyMs(duration)}, Bytes IN: ${bytesReceived}, OUT: ${bytesSent}`
+);
+```
+
+### 3. Active Connection Tracking
+
+```typescript
+getConnectionCount(): number {
+  return this.connectionRecords.size;
+}
+
+// In NetworkProxy
+metrics = {
+  activeConnections: this.connectedClients,
+  portProxyConnections: this.portProxyConnections,
+  tlsTerminatedConnections: this.tlsTerminatedConnections
+};
+```
+
+## Best Practices for Connection Termination
+
+1. **Always Use initiateCleanupOnce()**:
+   - Prevents duplicate cleanup operations
+   - Ensures proper termination reason tracking
+
+2. **Handle All Socket Events**:
+   - 'error', 'close', 'end' events
+   - Both incoming and outgoing sockets
+
+3. **Implement Proper Timeouts**:
+   - Initial data timeout
+   - Inactivity timeout  
+   - Maximum connection lifetime
+
+4. **Track Resources**:
+   - Connection records
+   - Socket maps
+   - Timer references
+
+5. **Log Termination Reasons**:
+   - Helps debug connection issues
+   - Provides metrics for monitoring
+
+6. **Graceful Shutdown**:
+   - Try socket.end() before socket.destroy()
+   - Allow time for graceful closure
+
+7. **Memory Management**:
+   - Clear pending data buffers
+   - Remove event listeners
+   - Delete connection records
+
+## Common Issues and Solutions
+
+### Issue: Memory Leaks from Event Listeners
+**Solution**: Always call removeAllListeners() during cleanup
+
+### Issue: Orphaned Connections
+**Solution**: Implement multiple cleanup triggers (timeout, error, close)
+
+### Issue: Duplicate Cleanup Operations
+**Solution**: Use connectionClosed flag and initiateCleanupOnce()
+
+### Issue: Hanging Connections
+**Solution**: Implement inactivity checks and maximum lifetime limits
+
+### Issue: Resource Exhaustion
+**Solution**: Track connection counts and implement limits
+
+### Issue: Lost Data During Cleanup
+**Solution**: Use proper unpipe operations and graceful shutdown
+
+### Issue: Debugging Connection Issues
+**Solution**: Track termination reasons and maintain detailed logs

+# NetworkProxy Connection Termination and SmartProxy Connection Handling
+
+## Overview
+
+The connection management between NetworkProxy and SmartProxy involves complex coordination to handle TLS termination, connection forwarding, and proper cleanup. This document outlines how these systems work together.
+
+## SmartProxy Connection Management
+
+### Connection Tracking (ConnectionManager)
+
+1. **Connection Lifecycle**:
+   - New connections are registered in `ConnectionManager.createConnection()`
+   - Each connection gets a unique ID and tracking record
+   - Connection records track both incoming (client) and outgoing (target) sockets
+   - Connections are removed from tracking upon cleanup
+
+2. **Connection Cleanup Flow**:
+   ```
+   initiateCleanupOnce() -> cleanupConnection() -> cleanupSocket()
+   ```
+   - `initiateCleanupOnce()`: Prevents duplicate cleanup operations
+   - `cleanupConnection()`: Main cleanup logic, removes connections from tracking
+   - `cleanupSocket()`: Handles socket termination (graceful end, then forced destroy)
+
+3. **Cleanup Triggers**:
+   - Socket errors (ECONNRESET, ETIMEDOUT, etc.)
+   - Socket close events
+   - Inactivity timeouts
+   - Connection lifetime limits
+   - Manual cleanup (e.g., NFTables-handled connections)
+
+## NetworkProxy Integration
+
+### NetworkProxyBridge
+
+The `NetworkProxyBridge` class manages the connection between SmartProxy and NetworkProxy:
+
+1. **Connection Forwarding**:
+   ```typescript
+   forwardToNetworkProxy(
+     connectionId: string,
+     socket: net.Socket,
+     record: IConnectionRecord,
+     initialChunk: Buffer,
+     networkProxyPort: number,
+     cleanupCallback: (reason: string) => void
+   )
+   ```
+   - Creates a new socket connection to NetworkProxy
+   - Pipes data between client and NetworkProxy sockets
+   - Sets up cleanup handlers for both sockets
+
+2. **Cleanup Coordination**:
+   - When either socket ends or errors, both are cleaned up
+   - Cleanup callback notifies SmartProxy's ConnectionManager
+   - Proper unpipe operations prevent memory leaks
+
+## NetworkProxy Connection Tracking
+
+### Connection Tracking in NetworkProxy
+
+1. **Raw TCP Connection Tracking**:
+   ```typescript
+   setupConnectionTracking(): void {
+     this.httpsServer.on('connection', (connection: net.Socket) => {
+       // Track connections in socketMap
+       this.socketMap.add(connection);
+       
+       // Setup cleanup handlers
+       connection.on('close', cleanupConnection);
+       connection.on('error', cleanupConnection);
+       connection.on('end', cleanupConnection);
+     });
+   }
+   ```
+
+2. **SmartProxy Connection Detection**:
+   - Connections from localhost (127.0.0.1) are identified as SmartProxy connections
+   - Special counter tracks `portProxyConnections`
+   - Connection counts are updated when connections close
+
+3. **Metrics and Monitoring**:
+   - Active connections tracked in `connectedClients`
+   - TLS handshake completions tracked in `tlsTerminatedConnections`
+   - Connection pool status monitored periodically
+
+## Connection Termination Flow
+
+### Typical TLS Termination Flow:
+
+1. Client connects to SmartProxy
+2. SmartProxy creates connection record and tracks socket
+3. SmartProxy determines route requires TLS termination
+4. NetworkProxyBridge forwards connection to NetworkProxy
+5. NetworkProxy performs TLS termination
+6. Data flows through piped sockets
+7. When connection ends:
+   - NetworkProxy cleans up its socket tracking
+   - NetworkProxyBridge handles cleanup coordination
+   - SmartProxy's ConnectionManager removes connection record
+   - All resources are properly released
+
+### Cleanup Coordination Points:
+
+1. **SmartProxy Cleanup**:
+   - ConnectionManager tracks all cleanup reasons
+   - Socket handlers removed to prevent memory leaks
+   - Timeout timers cleared
+   - Connection records removed from maps
+   - Security manager notified of connection removal
+
+2. **NetworkProxy Cleanup**:
+   - Sockets removed from tracking map
+   - Connection counters updated
+   - Metrics updated for monitoring
+   - Connection pool resources freed
+
+3. **Bridge Cleanup**:
+   - Unpipe operations prevent data loss
+   - Both sockets properly destroyed
+   - Cleanup callback ensures SmartProxy is notified
+
+## Important Considerations
+
+1. **Memory Management**:
+   - All event listeners must be removed during cleanup
+   - Proper unpipe operations prevent memory leaks
+   - Connection records cleared from all tracking maps
+
+2. **Error Handling**:
+   - Multiple cleanup mechanisms prevent orphaned connections
+   - Graceful shutdown attempted before forced destruction
+   - Timeout mechanisms ensure cleanup even in edge cases
+
+3. **State Consistency**:
+   - Connection closed flags prevent duplicate cleanup
+   - Termination reasons tracked for debugging
+   - Activity timestamps updated for accurate timeout handling
+
+4. **Performance**:
+   - Connection pools minimize TCP handshake overhead
+   - Efficient socket tracking using Maps
+   - Periodic cleanup prevents resource accumulation
+
+## Best Practices
+
+1. Always use `initiateCleanupOnce()` to prevent duplicate cleanup operations
+2. Track termination reasons for debugging and monitoring
+3. Ensure all event listeners are removed during cleanup
+4. Use proper unpipe operations when breaking socket connections
+5. Monitor connection counts and cleanup statistics
+6. Implement proper timeout handling for all connection types
+7. Keep socket tracking maps synchronized with actual socket state

 # Changelog
 
+## 2025-05-19 - 19.3.2 - fix(SmartCertManager)
+Preserve certificate manager update callback during route updates
+
+- Modify test cases (test.fix-verification.ts, test.route-callback-simple.ts, test.route-update-callback.node.ts) to verify that the updateRoutesCallback is preserved upon route updates.

+## Dynamic Route Updates
+
+When routes are updated dynamically using `updateRoutes()`, SmartProxy maintains certificate management continuity:
+
+```typescript
+// Update routes with new domains
+await proxy.updateRoutes([
+  {
+    name: 'new-domain',
+    match: { ports: 443, domains: 'newsite.example.com' },
+    action: {
+      type: 'forward',
+      target: { host: 'localhost', port: 8080 },
+      tls: {
+        mode: 'terminate',
+        certificate: 'auto'  // Will use global ACME config
+      }
+    }
+  }
+]);
+```
+
+### Important Notes on Route Updates
+
+1. **Certificate Manager Recreation**: When routes are updated, the certificate manager is recreated to reflect the new configuration
+2. **ACME Callbacks Preserved**: The ACME route update callback is automatically preserved during route updates
+3. **Existing Certificates**: Certificates already provisioned are retained in the certificate store
+4. **New Route Certificates**: New routes with `certificate: 'auto'` will trigger certificate provisioning
+
+### ACME Challenge Route Lifecycle
+
+SmartProxy v19.2.3+ implements an improved challenge route lifecycle to prevent port conflicts:
+
+1. **Single Challenge Route**: The ACME challenge route on port 80 is added once during initialization, not per certificate
+2. **Persistent During Provisioning**: The challenge route remains active throughout the entire certificate provisioning process
+3. **Concurrency Protection**: Certificate provisioning is serialized to prevent race conditions
+4. **Automatic Cleanup**: The challenge route is automatically removed when the certificate manager stops
+
+### Troubleshooting Port 80 Conflicts
+
+If you encounter "EADDRINUSE" errors on port 80:
+
+1. **Check Existing Services**: Ensure no other service is using port 80
+2. **Verify Configuration**: Confirm your ACME configuration specifies the correct port
+3. **Monitor Logs**: Check for "Challenge route already active" messages
+4. **Restart Clean**: If issues persist, restart SmartProxy to reset state
+
+### Route Update Best Practices
+
+1. **Batch Updates**: Update multiple routes in a single `updateRoutes()` call for efficiency
+2. **Monitor Certificate Status**: Check certificate status after route updates
+3. **Handle ACME Errors**: Implement error handling for certificate provisioning failures
+4. **Test Updates**: Test route updates in staging environment first
+5. **Check Port Availability**: Ensure port 80 is available before enabling ACME
+
 ## Best Practices
 
 1. **Always test with staging ACME servers first**
 2. **Set up monitoring for certificate expiration**
 3. **Use meaningful route names for easier certificate management**
 4. **Store static certificates securely with appropriate permissions**
-5. **Implement certificate status monitoring in production**
+5. **Implement certificate status monitoring in production**
+6. **Batch route updates when possible to minimize disruption**
+7. **Monitor certificate provisioning after route updates**

+# Port 80 ACME Management in SmartProxy
+
+## Overview
+
+SmartProxy correctly handles port management when both user routes and ACME challenges need to use the same port (typically port 80). This document explains how the system prevents port conflicts and EADDRINUSE errors.
+
+## Port Deduplication
+
+SmartProxy's PortManager implements automatic port deduplication:
+
+```typescript
+public async addPort(port: number): Promise<void> {
+  // Check if we're already listening on this port
+  if (this.servers.has(port)) {
+    console.log(`PortManager: Already listening on port ${port}`);
+    return;
+  }
+  
+  // Create server for this port...
+}
+```
+
+This means that when both a user route and ACME challenges are configured to use port 80, the port is only opened once and shared between both use cases.
+
+## ACME Challenge Route Flow
+
+1. **Initialization**: When SmartProxy starts and detects routes with `certificate: 'auto'`, it initializes the certificate manager
+2. **Challenge Route Creation**: The certificate manager creates a special challenge route on the configured ACME port (default 80)
+3. **Route Update**: The challenge route is added via `updateRoutes()`, which triggers port allocation
+4. **Deduplication**: If port 80 is already in use by a user route, the PortManager's deduplication prevents double allocation
+5. **Shared Access**: Both user routes and ACME challenges share the same port listener
+
+## Configuration Examples
+
+### Shared Port (Recommended)
+
+```typescript
+const settings = {
+  routes: [
+    {
+      name: 'web-traffic',
+      match: {
+        ports: [80]
+      },
+      action: {
+        type: 'forward',
+        targetUrl: 'http://localhost:3000'
+      }
+    },
+    {
+      name: 'secure-traffic',
+      match: {
+        ports: [443]
+      },
+      action: {
+        type: 'forward',
+        targetUrl: 'https://localhost:3001',
+        tls: {
+          mode: 'terminate',
+          certificate: 'auto'
+        }
+      }
+    }
+  ],
+  acme: {
+    email: 'your-email@example.com',
+    port: 80  // Same as user route - this is safe!
+  }
+};
+```
+
+### Separate ACME Port
+
+```typescript
+const settings = {
+  routes: [
+    {
+      name: 'web-traffic',
+      match: {
+        ports: [80]
+      },
+      action: {
+        type: 'forward',
+        targetUrl: 'http://localhost:3000'
+      }
+    }
+  ],
+  acme: {
+    email: 'your-email@example.com',
+    port: 8080  // Different port for ACME challenges
+  }
+};
+```
+
+## Best Practices
+
+1. **Use Default Port 80**: Let ACME use port 80 (the default) even if you have user routes on that port
+2. **Priority Routing**: ACME challenge routes have high priority (1000) to ensure they take precedence
+3. **Path-Based Routing**: ACME routes only match `/.well-known/acme-challenge/*` paths, avoiding conflicts
+4. **Automatic Cleanup**: Challenge routes are automatically removed when not needed
+
+## Troubleshooting
+
+### EADDRINUSE Errors
+
+If you see EADDRINUSE errors, check:
+
+1. Is another process using the port?
+2. Are you running multiple SmartProxy instances?
+3. Is the previous instance still shutting down?
+
+### Certificate Provisioning Issues
+
+1. Ensure the ACME port is accessible from the internet
+2. Check that DNS is properly configured for your domains
+3. Verify email configuration in ACME settings
+
+## Technical Details
+
+The port deduplication is handled at multiple levels:
+
+1. **PortManager Level**: Checks if port is already active before creating new listener
+2. **RouteManager Level**: Tracks which ports are needed and updates accordingly
+3. **Certificate Manager Level**: Adds challenge route only when needed
+
+This multi-level approach ensures robust port management without conflicts.

-# SmartProxy ACME Simplification Plan
+# SmartProxy Development Plan
 
-## Overview
-This plan addresses the certificate acquisition confusion in SmartProxy v19.0.0 and proposes simplifications to make ACME configuration more intuitive.
+cat /home/philkunz/.claude/CLAUDE.md
 
-## Current Issues
-1. ACME configuration placement is confusing (route-level vs top-level)
-2. SmartAcme initialization logic is complex and error-prone
-3. Documentation doesn't clearly explain the correct configuration format
-4. Error messages like "SmartAcme not initialized" are not helpful
+## Critical Bug Fix: Port 80 EADDRINUSE with ACME Challenge Routes
 
-## Proposed Simplifications
+### Problem Statement
+SmartProxy encounters an "EADDRINUSE" error on port 80 when provisioning multiple ACME certificates. The issue occurs because the certificate manager adds and removes the challenge route for each certificate individually, causing race conditions when multiple certificates are provisioned concurrently.
 
-### 1. Support Both Configuration Styles
-- [x] Reread CLAUDE.md before starting implementation
-- [x] Accept ACME config at both top-level and route-level
-- [x] Use top-level ACME config as defaults for all routes
-- [x] Allow route-level ACME config to override top-level defaults
-- [x] Make email field required when any route uses `certificate: 'auto'`
+### Root Cause
+The `SmartCertManager` class adds the ACME challenge route (port 80) before provisioning each certificate and removes it afterward. When multiple certificates are provisioned:
+1. Each provisioning cycle adds its own challenge route
+2. This triggers `updateRoutes()` which calls `PortManager.updatePorts()`
+3. Port 80 is repeatedly added/removed, causing binding conflicts
 
-### 2. Improve SmartAcme Initialization
-- [x] Initialize SmartAcme when top-level ACME config exists with email
-- [x] Initialize SmartAcme when any route has `certificate: 'auto'`
-- [x] Provide clear error messages when initialization fails
-- [x] Add debug logging for ACME initialization steps
+### Implementation Plan
 
-### 3. Simplify Certificate Configuration
-- [x] Create helper method to validate ACME configuration
-- [x] Auto-detect when port 80 is needed for challenges
-- [x] Provide sensible defaults for ACME settings
-- [x] Add configuration examples in documentation
+#### Phase 1: Refactor Challenge Route Lifecycle
+1. **Modify challenge route handling** in `SmartCertManager`
+   - [x] Add challenge route once during initialization if ACME is configured
+   - [x] Keep challenge route active throughout entire certificate provisioning
+   - [x] Remove challenge route only after all certificates are provisioned
+   - [x] Add concurrency control to prevent multiple simultaneous route updates
 
-### 4. Update Documentation
-- [x] Create clear examples for common ACME scenarios
-- [x] Document the configuration hierarchy (top-level vs route-level)
-- [x] Add troubleshooting guide for common certificate issues
-- [x] Include migration guide from v18 to v19
+#### Phase 2: Update Certificate Provisioning Flow
+2. **Refactor certificate provisioning methods**
+   - [x] Separate challenge route management from individual certificate provisioning
+   - [x] Update `provisionAcmeCertificate()` to not add/remove challenge routes
+   - [x] Modify `provisionAllCertificates()` to handle challenge route lifecycle
+   - [x] Add error handling for challenge route initialization failures
 
-### 5. Add Configuration Helpers
-- [x] Create `SmartProxyConfig.fromSimple()` helper for basic setups (part of validation)
-- [x] Add validation for common misconfigurations
-- [x] Provide warning messages for deprecated patterns
-- [x] Include auto-correction suggestions
+#### Phase 3: Implement Concurrency Controls
+3. **Add synchronization mechanisms**
+   - [x] Implement mutex/lock for challenge route operations
+   - [x] Ensure certificate provisioning is properly serialized
+   - [x] Add safeguards against duplicate challenge routes
+   - [x] Handle edge cases (shutdown during provisioning, renewal conflicts)
 
-## Implementation Steps
+#### Phase 4: Enhance Error Handling
+4. **Improve error handling and recovery**
+   - [x] Add specific error types for port conflicts
+   - [x] Implement retry logic for transient port binding issues
+   - [x] Add detailed logging for challenge route lifecycle
+   - [x] Ensure proper cleanup on errors
 
-### Phase 1: Configuration Support ✅
-1. ✅ Update ISmartProxyOptions interface to clarify ACME placement
-2. ✅ Modify SmartProxy constructor to handle top-level ACME config
-3. ✅ Update SmartCertManager to accept global ACME defaults
-4. ✅ Add configuration validation and helpful error messages
+#### Phase 5: Create Comprehensive Tests
+5. **Write tests for challenge route management**
+   - [x] Test concurrent certificate provisioning
+   - [x] Test challenge route persistence during provisioning
+   - [x] Test error scenarios (port already in use)
+   - [x] Test cleanup after provisioning
+   - [x] Test renewal scenarios with existing challenge routes
 
-### Phase 2: Testing ✅
-1. ✅ Add tests for both configuration styles
-2. ✅ Test ACME initialization with various configurations
-3. ✅ Verify certificate acquisition works in all scenarios

+   - [x] Update certificate management documentation
+   - [x] Add troubleshooting guide for port conflicts
+   - [x] Document the challenge route lifecycle
+   - [x] Include examples of proper ACME configuration
 
-### Phase 3: Documentation ✅
-1. ✅ Update main README with clear ACME examples
-2. ✅ Create dedicated certificate-management.md guide
-3. ✅ Add migration guide for v18 to v19 users
-4. ✅ Include troubleshooting section
+### Technical Details
 
-## Example Simplified Configuration
+#### Specific Code Changes
 
-```typescript
-// Simplified configuration with top-level ACME
-const proxy = new SmartProxy({
-  // Global ACME settings (applies to all routes with certificate: 'auto')
-  acme: {
-    email: 'ssl@example.com',
-    useProduction: false,
-    port: 80  // Automatically listened on when needed
-  },
-  
-  routes: [
-    {
-      name: 'secure-site',
-      match: { domains: 'example.com', ports: 443 },
-      action: {
-        type: 'forward',
-        target: { host: 'localhost', port: 8080 },
-        tls: {
-          mode: 'terminate',
-          certificate: 'auto'  // Uses global ACME settings
-        }
-      }
-    }
-  ]
-});
+1. In `SmartCertManager.initialize()`:
+   ```typescript
+   // Add challenge route once at initialization
+   if (hasAcmeRoutes && this.acmeOptions?.email) {
+     await this.addChallengeRoute();
+   }
+   ```
 
-// Or with route-specific ACME override
-const proxy = new SmartProxy({
-  routes: [
-    {
-      name: 'special-site',
-      match: { domains: 'special.com', ports: 443 },
-      action: {
-        type: 'forward',
-        target: { host: 'localhost', port: 8080 },
-        tls: {
-          mode: 'terminate',
-          certificate: 'auto',
-          acme: {  // Route-specific override
-            email: 'special@example.com',
-            useProduction: true
-          }
-        }
-      }
-    }
-  ]
-});
-```
+2. Modify `provisionAcmeCertificate()`:
+   ```typescript
+   // Remove these lines:
+   // await this.addChallengeRoute();
+   // await this.removeChallengeRoute();
+   ```
 
-## Success Criteria ✅
-1. ✅ Users can configure ACME at top-level for all routes
-2. ✅ Clear error messages guide users to correct configuration
-3. ✅ Certificate acquisition works with minimal configuration
-4. ✅ Documentation clearly explains all configuration options
-5. ✅ Migration from v18 to v19 is straightforward
+3. Update `stop()` method:
+   ```typescript
+   // Always remove challenge route on shutdown
+   if (this.challengeRoute) {
+     await this.removeChallengeRoute();
+   }
+   ```
 
-## Timeline
-- Phase 1: 2-3 days
-- Phase 2: 1-2 days  
-- Phase 3: 1 day
+4. Add concurrency control:
+   ```typescript
+   private challengeRouteLock = new AsyncLock();
+   
+   private async manageChallengeRoute(operation: 'add' | 'remove'): Promise<void> {
+     await this.challengeRouteLock.acquire('challenge-route', async () => {
+       if (operation === 'add') {
+         await this.addChallengeRoute();
+       } else {
+         await this.removeChallengeRoute();
+       }
+     });
+   }
+   ```
 
-Total estimated time: 5-6 days
+### Success Criteria
+- [x] No EADDRINUSE errors when provisioning multiple certificates
+- [x] Challenge route remains active during entire provisioning cycle
+- [x] Port 80 is only bound once per SmartProxy instance

+- Consider impact on renewal operations and edge cases
+
+## NEW FINDINGS: Additional Port Management Issues
+
+### Problem Statement
+Further investigation has revealed additional issues beyond the initial port 80 EADDRINUSE error:
+
+1. **Race Condition in updateRoutes**: Certificate manager is recreated during route updates, potentially causing duplicate challenge routes
+2. **Lost State**: The `challengeRouteActive` flag is not persisted when certificate manager is recreated
+3. **No Global Synchronization**: Multiple concurrent route updates can create conflicting certificate managers
+4. **Incomplete Cleanup**: Challenge route removal doesn't verify actual port release
+
+### Implementation Plan for Additional Fixes
+
+#### Phase 1: Fix updateRoutes Race Condition
+1. **Preserve certificate manager state during route updates**
+   - [x] Track active challenge routes at SmartProxy level
+   - [x] Pass existing state to new certificate manager instances
+   - [x] Ensure challenge route is only added once across recreations
+   - [x] Add proper cleanup before recreation
+
+#### Phase 2: Implement Global Route Update Lock
+2. **Add synchronization for route updates**
+   - [x] Implement mutex/semaphore for `updateRoutes` method
+   - [x] Prevent concurrent certificate manager recreations
+   - [x] Ensure atomic route updates
+   - [x] Add timeout handling for locks
+
+#### Phase 3: Improve State Management
+3. **Persist critical state across certificate manager instances**
+   - [x] Create global state store for ACME operations
+   - [x] Track active challenge routes globally
+   - [x] Maintain port allocation state
+   - [x] Add state recovery mechanisms
+
+#### Phase 4: Enhance Cleanup Verification
+4. **Verify resource cleanup before recreation**
+   - [x] Wait for old certificate manager to fully stop
+   - [x] Verify challenge route removal from port manager
+   - [x] Add cleanup confirmation callbacks
+   - [x] Implement rollback on cleanup failure
+
+#### Phase 5: Add Comprehensive Testing
+5. **Test race conditions and edge cases**
+   - [x] Test rapid route updates with ACME
+   - [x] Test concurrent certificate manager operations
+   - [x] Test state persistence across recreations
+   - [x] Test cleanup verification logic
+
+### Technical Implementation
+
+1. **Global Challenge Route Tracker**:
+   ```typescript
+   class SmartProxy {
+     private globalChallengeRouteActive = false;
+     private routeUpdateLock = new Mutex();
+     
+     async updateRoutes(newRoutes: IRouteConfig[]): Promise<void> {
+       await this.routeUpdateLock.runExclusive(async () => {
+         // Update logic here
+       });
+     }
+   }
+   ```
+
+2. **State Preservation**:
+   ```typescript
+   if (this.certManager) {
+     const state = {
+       challengeRouteActive: this.globalChallengeRouteActive,
+       acmeOptions: this.certManager.getAcmeOptions(),
+       // ... other state
+     };
+     
+     await this.certManager.stop();
+     await this.verifyChallengeRouteRemoved();
+     
+     this.certManager = await this.createCertificateManager(
+       newRoutes,
+       './certs',
+       state
+     );
+   }
+   ```
+
+3. **Cleanup Verification**:
+   ```typescript
+   private async verifyChallengeRouteRemoved(): Promise<void> {
+     const maxRetries = 10;
+     for (let i = 0; i < maxRetries; i++) {
+       if (!this.portManager.isListening(80)) {
+         return;
+       }
+       await this.sleep(100);
+     }
+     throw new Error('Failed to verify challenge route removal');
+   }
+   ```
+
+### Success Criteria
+- [ ] No race conditions during route updates
+- [ ] State properly preserved across certificate manager recreations
+- [ ] No duplicate challenge routes
+- [ ] Clean resource management
+- [ ] All edge cases handled gracefully
+
+### Timeline for Additional Fixes
+- Phase 1: 3 hours (Race condition fix)
+- Phase 2: 2 hours (Global synchronization)
+- Phase 3: 2 hours (State management)
+- Phase 4: 2 hours (Cleanup verification)
+- Phase 5: 3 hours (Testing)
+
+Total estimated time: 12 hours
+
+### Priority
+These additional fixes are HIGH PRIORITY as they address fundamental issues that could cause:
+- Port binding errors
+- Certificate provisioning failures
+- Resource leaks
+- Inconsistent proxy state
+
+The fixes should be implemented immediately after the initial port 80 EADDRINUSE fix is deployed.
+
+### Implementation Complete
+
+All additional port management issues have been successfully addressed:
+
+1. **Mutex Implementation**: Created a custom `Mutex` class for synchronizing route updates
+2. **Global State Tracking**: Implemented `AcmeStateManager` to track challenge routes globally
+3. **State Preservation**: Modified `SmartCertManager` to accept and preserve state across recreations
+4. **Cleanup Verification**: Added `verifyChallengeRouteRemoved` method to ensure proper cleanup
+5. **Comprehensive Testing**: Created test suites for race conditions and state management
+
+The implementation ensures:
+- No concurrent route updates can create conflicting states
+- Challenge route state is preserved across certificate manager recreations
+- Port 80 is properly managed without EADDRINUSE errors
+- All resources are cleaned up properly during shutdown
+
+All tests are ready to run and the implementation is complete.

-# ACME/Certificate Simplification Summary
-
-## What Was Done
-
-We successfully implemented the ACME/Certificate simplification plan for SmartProxy:
-
-### 1. Created New Certificate Management System
-
-- **SmartCertManager** (`ts/proxies/smart-proxy/certificate-manager.ts`): A unified certificate manager that handles both ACME and static certificates
-- **CertStore** (`ts/proxies/smart-proxy/cert-store.ts`): File-based certificate storage system
-
-### 2. Updated Route Types
-
-- Added `IRouteAcme` interface for ACME configuration
-- Added `IStaticResponse` interface for static route responses
-- Extended `IRouteTls` with comprehensive certificate options
-- Added `handler` property to `IRouteAction` for static routes
-
-### 3. Implemented Static Route Handler
-
-- Added `handleStaticAction` method to route-connection-handler.ts
-- Added support for 'static' route type in the action switch statement
-- Implemented proper HTTP response formatting
-
-### 4. Updated SmartProxy Integration
-
-- Removed old CertProvisioner and Port80Handler dependencies
-- Added `initializeCertificateManager` method
-- Updated `start` and `stop` methods to use new certificate manager
-- Added `provisionCertificate`, `renewCertificate`, and `getCertificateStatus` methods
-
-### 5. Simplified NetworkProxyBridge
-
-- Removed all certificate-related logic
-- Simplified to only handle network proxy forwarding
-- Updated to use port-based matching for network proxy routes
-
-### 6. Cleaned Up HTTP Module
-
-- Removed exports for port80 subdirectory
-- Kept only router and redirect functionality
-
-### 7. Created Tests
-
-- Created simplified test for certificate functionality
-- Test demonstrates static route handling and basic certificate configuration
-
-## Key Improvements
-
-1. **No Backward Compatibility**: Clean break from legacy implementations
-2. **Direct SmartAcme Integration**: Uses @push.rocks/smartacme directly without custom wrappers
-3. **Route-Based ACME Challenges**: No separate HTTP server needed
-4. **Simplified Architecture**: Removed unnecessary abstraction layers
-5. **Unified Configuration**: Certificate configuration is part of route definitions
-
-## Configuration Example
-
-```typescript
-const proxy = new SmartProxy({
-  routes: [{
-    name: 'secure-site',
-    match: { ports: 443, domains: 'example.com' },
-    action: {
-      type: 'forward',
-      target: { host: 'backend', port: 8080 },
-      tls: {
-        mode: 'terminate',
-        certificate: 'auto',
-        acme: {
-          email: 'admin@example.com',
-          useProduction: true
-        }
-      }
-    }
-  }]
-});
-```
-
-## Next Steps
-
-1. Remove old certificate module and port80 directory
-2. Update documentation with new configuration format
-3. Test with real ACME certificates in staging environment
-4. Add more comprehensive tests for renewal and edge cases
-
-The implementation is complete and builds successfully!

-# NFTables Naming Consolidation Summary
-
-This document summarizes the changes made to consolidate the naming convention for IP allow/block lists in the NFTables integration.
-
-## Changes Made
-
-1. **Updated NFTablesProxy interface** (`ts/proxies/nftables-proxy/models/interfaces.ts`):
-   - Changed `allowedSourceIPs` to `ipAllowList`
-   - Changed `bannedSourceIPs` to `ipBlockList`
-
-2. **Updated NFTablesProxy implementation** (`ts/proxies/nftables-proxy/nftables-proxy.ts`):
-   - Updated all references from `allowedSourceIPs` to `ipAllowList`
-   - Updated all references from `bannedSourceIPs` to `ipBlockList`
-
-3. **Updated NFTablesManager** (`ts/proxies/smart-proxy/nftables-manager.ts`):
-   - Changed mapping from `allowedSourceIPs` to `ipAllowList`
-   - Changed mapping from `bannedSourceIPs` to `ipBlockList`
-
-## Files Already Using Consistent Naming
-
-The following files already used the consistent naming convention `ipAllowList` and `ipBlockList`:
-
-1. **Route helpers** (`ts/proxies/smart-proxy/utils/route-helpers.ts`)
-2. **Integration test** (`test/test.nftables-integration.ts`)
-3. **NFTables example** (`examples/nftables-integration.ts`)
-4. **Route types** (`ts/proxies/smart-proxy/models/route-types.ts`)
-
-## Result
-
-The naming is now consistent throughout the codebase:
-- `ipAllowList` is used for lists of allowed IP addresses
-- `ipBlockList` is used for lists of blocked IP addresses
-
-This matches the naming convention already established in SmartProxy's core routing system.
