 # Changelog
 
+## 2025-05-15 - 17.0.0 - BREAKING CHANGE(smartproxy)
+Remove legacy migration utilities and deprecated forwarding helpers; consolidate route utilities, streamline interface definitions, and normalize IPv6-mapped IPv4 addresses
+
+- Deleted ts/proxies/smart-proxy/utils/route-migration-utils.ts and removed its re-exports
+- Removed deprecated helper functions (httpOnly, tlsTerminateToHttp, tlsTerminateToHttps, httpsPassthrough) from ts/forwarding/config/forwarding-types.ts
+- Updated ts/common/port80-adapter.ts to consistently normalize IPv6-mapped IPv4 addresses in IP comparisons
+- Cleaned up legacy connection handling code in route-connection-handler.ts by removing unused parameters and obsolete comments
+- Consolidated route utilities by replacing imports from route-helpers.js with route-patterns.js in multiple modules
+- Simplified interface definitions by removing legacy aliases and type checking functions from models/interfaces.ts
+- Enhanced type safety by replacing any remaining 'any' types with specific types throughout the codebase
+- Updated documentation comments and removed references to deprecated functionality
+
+## 2025-05-14 - 16.0.4 - fix(smartproxy)
+Update dynamic port mapping to support 'preserve' target port value
+
+- Refactored NetworkProxy to use a default port for 'preserve' values, correctly falling back to the incoming port when target.port is set to 'preserve'.
+- Updated RequestHandler and WebSocketHandler to check for 'preserve' target port instead of legacy preservePort flag.
+- Modified IRouteTarget type definitions to allow 'preserve' as a valid target port value.
+
+## 2025-05-14 - 16.0.4 - fix(smartproxy)
+Fix dynamic port mapping: update target port resolution to properly handle 'preserve' values across route configurations. Now, when a route's target port is set to 'preserve', the incoming port is used consistently in NetworkProxy, RequestHandler, WebSocketHandler, and RouteConnectionHandler. Also update type definitions in IRouteTarget to support 'preserve'.
+
+- Refactored port resolution in NetworkProxy to use a default port for 'preserve' and then correctly fall back to the incoming port when 'preserve' is specified.
+- Updated RequestHandler and WebSocketHandler to check if target.port equals 'preserve' instead of using a legacy 'preservePort' flag.
+- Modified RouteConnectionHandler to correctly resolve dynamic port mappings with 'preserve'.
+- Updated route type definitions to allow 'preserve' as a valid target port value.
+
+## 2025-05-14 - 16.0.3 - fix(network-proxy, route-utils, route-manager)
+Normalize IPv6-mapped IPv4 addresses in IP matching functions and remove deprecated legacy configuration methods in NetworkProxy. Update route-utils and route-manager to compare both canonical and IPv6-mapped IP forms, adjust tests accordingly, and clean up legacy exports.
+
+- Updated matchIpPattern and matchIpCidr to normalize IPv6-mapped IPv4 addresses.
+- Replaced legacy 'domain' field references with 'domains' in route configurations.
+- Removed deprecated methods for converting legacy proxy configs and legacy route helpers.
+- Adjusted test cases (event system, route utils, network proxy function targets) to use modern interfaces.
+- Improved logging and error messages in route-manager and route-utils for better debugging.
+
+## 2025-05-10 - 16.0.2 - fix(test/certificate-provisioning)
+Update certificate provisioning tests with updated port mapping and ACME options; use accountEmail instead of contactEmail, adjust auto-api route creation to use HTTPS terminate helper, and refine expectations for wildcard passthrough domains.
+
+- Changed portMap mapping: HTTP now maps 80 to 8080 and HTTPS from 443 to 4443
+- Replaced 'contactEmail' with 'accountEmail' in ACME configuration (set to 'test@bleu.de')
+- Updated auto-api route to use createHttpsTerminateRoute instead of createApiRoute for consistency
+- Adjusted expectations: passthrough domains are now included in certificate extraction when using terminate route with certificate 'auto'
+- Minor cleanup in test event handling and proxy stop routines

+# SmartProxy Port Handling
+
+This document covers all the port handling capabilities in SmartProxy, including port range specification, dynamic port mapping, and runtime port management.
+
+## Port Range Syntax
+
+SmartProxy offers flexible port range specification through the `TPortRange` type, which can be defined in three different ways:
+
+### 1. Single Port
+
+```typescript
+// Match a single port
+{
+  match: {
+    ports: 443
+  }
+}
+```
+
+### 2. Array of Specific Ports
+
+```typescript
+// Match multiple specific ports
+{
+  match: {
+    ports: [80, 443, 8080]
+  }
+}
+```
+
+### 3. Port Range
+
+```typescript
+// Match a range of ports
+{
+  match: {
+    ports: [{ from: 8000, to: 8100 }]
+  }
+}
+```
+
+### 4. Mixed Port Specifications
+
+You can combine different port specification methods in a single rule:
+
+```typescript
+// Match both specific ports and port ranges
+{
+  match: {
+    ports: [80, 443, { from: 8000, to: 8100 }]
+  }
+}
+```
+
+## Port Forwarding Options
+
+SmartProxy offers several ways to handle port forwarding from source to target:
+
+### 1. Static Port Forwarding
+
+Forward to a fixed target port:
+
+```typescript
+{
+  action: {
+    type: 'forward',
+    target: {
+      host: 'backend.example.com',
+      port: 8080
+    }
+  }
+}
+```
+
+### 2. Preserve Source Port
+
+Forward to the same port on the target:
+
+```typescript
+{
+  action: {
+    type: 'forward',
+    target: {
+      host: 'backend.example.com',
+      port: 'preserve'
+    }
+  }
+}
+```
+
+### 3. Dynamic Port Mapping
+
+Use a function to determine the target port based on connection context:
+
+```typescript
+{
+  action: {
+    type: 'forward',
+    target: {
+      host: 'backend.example.com',
+      port: (context) => {
+        // Calculate port based on request details
+        return 8000 + (context.port % 100);
+      }
+    }
+  }
+}
+```
+
+## Port Selection Context
+
+When using dynamic port mapping functions, you have access to a rich context object that provides details about the connection:
+
+```typescript
+interface IRouteContext {
+  // Connection information
+  port: number;          // The matched incoming port
+  domain?: string;       // The domain from SNI or Host header
+  clientIp: string;      // The client's IP address
+  serverIp: string;      // The server's IP address
+  path?: string;         // URL path (for HTTP connections)
+  query?: string;        // Query string (for HTTP connections)
+  headers?: Record<string, string>; // HTTP headers (for HTTP connections)
+
+  // TLS information
+  isTls: boolean;        // Whether the connection is TLS
+  tlsVersion?: string;   // TLS version if applicable
+
+  // Route information
+  routeName?: string;    // The name of the matched route
+  routeId?: string;      // The ID of the matched route
+
+  // Additional properties
+  timestamp: number;     // The request timestamp
+  connectionId: string;  // Unique connection identifier
+}
+```
+
+## Common Port Mapping Patterns
+
+### 1. Port Offset Mapping
+
+Forward traffic to target ports with a fixed offset:
+
+```typescript
+{
+  action: {
+    type: 'forward',
+    target: {
+      host: 'backend.example.com',
+      port: (context) => context.port + 1000
+    }
+  }
+}
+```
+
+### 2. Domain-Based Port Mapping
+
+Forward to different backend ports based on the domain:
+
+```typescript
+{
+  action: {
+    type: 'forward',
+    target: {
+      host: 'backend.example.com',
+      port: (context) => {
+        switch (context.domain) {
+          case 'api.example.com': return 8001;
+          case 'admin.example.com': return 8002;
+          case 'staging.example.com': return 8003;
+          default: return 8000;
+        }
+      }
+    }
+  }
+}
+```
+
+### 3. Load Balancing with Hash-Based Distribution
+
+Distribute connections across a port range using a deterministic hash function:
+
+```typescript
+{
+  action: {
+    type: 'forward',
+    target: {
+      host: 'backend.example.com',
+      port: (context) => {
+        // Simple hash function to ensure consistent mapping
+        const hostname = context.domain || '';
+        const hash = hostname.split('').reduce((a, b) => a + b.charCodeAt(0), 0);
+        return 8000 + (hash % 10); // Map to ports 8000-8009
+      }
+    }
+  }
+}
+```
+
+## IPv6-Mapped IPv4 Compatibility
+
+SmartProxy automatically handles IPv6-mapped IPv4 addresses for optimal compatibility. When a connection from an IPv4 address (e.g., `192.168.1.1`) arrives as an IPv6-mapped address (`::ffff:192.168.1.1`), the system normalizes these addresses for consistent matching.
+
+This is particularly important when:
+
+1. Matching client IP restrictions in route configurations
+2. Preserving source IP for outgoing connections
+3. Tracking connections and rate limits
+
+No special configuration is needed - the system handles this normalization automatically.
+
+## Dynamic Port Management
+
+SmartProxy allows for runtime port configuration changes without requiring a restart.
+
+### Adding and Removing Ports
+
+```typescript
+// Get the SmartProxy instance
+const proxy = new SmartProxy({ /* config */ });
+
+// Add a new listening port
+await proxy.addListeningPort(8081);
+
+// Remove a listening port
+await proxy.removeListeningPort(8082);
+```
+
+### Runtime Route Updates
+
+```typescript
+// Get current routes
+const currentRoutes = proxy.getRoutes();
+
+// Add new route for the new port
+const newRoute = {
+  name: 'New Dynamic Route',
+  match: {
+    ports: 8081,
+    domains: ['dynamic.example.com']
+  },
+  action: {
+    type: 'forward',
+    target: {
+      host: 'backend.example.com',
+      port: 9000
+    }
+  }
+};
+
+// Update the route configuration
+await proxy.updateRoutes([...currentRoutes, newRoute]);
+
+// Remove routes for a specific port
+const routesWithout8082 = currentRoutes.filter(route => {
+  const ports = proxy.routeManager.expandPortRange(route.match.ports);
+  return !ports.includes(8082);
+});
+await proxy.updateRoutes(routesWithout8082);
+```
+
+## Performance Considerations
+
+### Port Range Expansion
+
+When using large port ranges, SmartProxy uses internal caching to optimize performance. For example, a range like `{ from: 1000, to: 2000 }` is expanded only once and then cached for future use.
+
+### Port Range Validation
+
+The system automatically validates port ranges to ensure:
+
+1. Port numbers are within the valid range (1-65535)
+2. The "from" value is not greater than the "to" value in range specifications
+3. Port ranges do not contain duplicate entries
+
+Invalid port ranges will be logged as warnings and skipped during configuration.
+
+## Configuration Recipes
+
+### Global Port Range
+
+Listen on a large range of ports and forward to the same ports on a backend:
+
+```typescript
+{
+  name: 'Global port range forwarding',
+  match: {
+    ports: [{ from: 8000, to: 9000 }]
+  },
+  action: {
+    type: 'forward',
+    target: {
+      host: 'backend.example.com',
+      port: 'preserve'
+    }
+  }
+}
+```
+
+### Domain-Specific Port Ranges
+
+Different port ranges for different domain groups:
+
+```typescript
+[
+  {
+    name: 'API port range',
+    match: {
+      ports: [{ from: 8000, to: 8099 }]
+    },
+    action: {
+      type: 'forward',
+      target: {
+        host: 'api.backend.example.com',
+        port: 'preserve'
+      }
+    }
+  },
+  {
+    name: 'Admin port range',
+    match: {
+      ports: [{ from: 9000, to: 9099 }]
+    },
+    action: {
+      type: 'forward',
+      target: {
+        host: 'admin.backend.example.com',
+        port: 'preserve'
+      }
+    }
+  }
+]
+```
+
+### Mixed Internal/External Port Forwarding
+
+Forward specific high-numbered ports to standard ports on internal servers:
+
+```typescript
+[
+  {
+    name: 'Web server forwarding',
+    match: {
+      ports: [8080, 8443]
+    },
+    action: {
+      type: 'forward',
+      target: {
+        host: 'web.internal',
+        port: (context) => context.port === 8080 ? 80 : 443
+      }
+    }
+  },
+  {
+    name: 'Database forwarding',
+    match: {
+      ports: [15432]
+    },
+    action: {
+      type: 'forward',
+      target: {
+        host: 'db.internal',
+        port: 5432
+      }
+    }
+  }
+]
+```
+
+## Debugging Port Configurations
+
+When troubleshooting port forwarding issues, enable detailed logging:
+
+```typescript
+const proxy = new SmartProxy({
+  routes: [ /* your routes */ ],
+  enableDetailedLogging: true
+});
+```
+
+This will log:
+- Port configuration during startup
+- Port matching decisions during routing
+- Dynamic port function results
+- Connection details including source and target ports
+
+## Port Security Considerations
+
+### Restricting Ports
+
+For security, you may want to restrict which ports can be accessed by specific clients:
+
+```typescript
+{
+  name: 'Restricted port range',
+  match: {
+    ports: [{ from: 8000, to: 9000 }],
+    clientIp: ['10.0.0.0/8'] // Only internal network can access these ports
+  },
+  action: {
+    type: 'forward',
+    target: {
+      host: 'internal.example.com',
+      port: 'preserve'
+    }
+  }
+}
+```
+
+### Rate Limiting by Port
+
+Apply different rate limits for different port ranges:
+
+```typescript
+{
+  name: 'API ports with rate limiting',
+  match: {
+    ports: [{ from: 8000, to: 8100 }]
+  },
+  action: {
+    type: 'forward',
+    target: {
+      host: 'api.example.com',
+      port: 'preserve'
+    },
+    security: {
+      rateLimit: {
+        enabled: true,
+        maxRequests: 100,
+        window: 60 // 60 seconds
+      }
+    }
+  }
+}
+```
+
+## Best Practices
+
+1. **Use Specific Port Ranges**: Instead of large ranges (e.g., 1-65535), use specific ranges for specific purposes
+
+2. **Prioritize Routes**: When multiple routes could match, use the `priority` field to ensure the most specific route is matched first
+
+3. **Name Your Routes**: Use descriptive names to make debugging easier, especially when using port ranges
+
+4. **Use Preserve Port Where Possible**: Using `port: 'preserve'` is more efficient and easier to maintain than creating multiple specific mappings
+
+5. **Limit Dynamic Port Functions**: While powerful, complex port functions can be harder to debug; prefer simple map or math-based functions
+
+6. **Use Port Variables**: For complex setups, define your port ranges as variables for easier maintenance:
+
+```typescript
+const API_PORTS = [{ from: 8000, to: 8099 }];
+const ADMIN_PORTS = [{ from: 9000, to: 9099 }];
+
+const routes = [
+  {
+    name: 'API Routes',
+    match: { ports: API_PORTS, /* ... */ },
+    // ...
+  },
+  {
+    name: 'Admin Routes',
+    match: { ports: ADMIN_PORTS, /* ... */ },
+    // ...
+  }
+];
+```

+### 1.3 Remove Deprecated Forwarding Types and Helpers ✅
 
-## Clean Break Approach
+Legacy forwarding types and helper functions in forwarding-types.ts are marked as deprecated.
 
-To keep our codebase as clean as possible, we are taking a clean break approach with NO migration or compatibility support for domain-based configuration. We will:
+- **Action:** ✅ 
+  - ✅ Clean up `/ts/forwarding/config/forwarding-types.ts`
+  - ✅ Remove deprecated helper functions: `httpOnly`, `tlsTerminateToHttp`, `tlsTerminateToHttps`, `httpsPassthrough`
+  - ✅ Remove deprecated interfaces: `IDeprecatedForwardConfig`
+- **Impact:** Medium - May break code that still uses these helpers
+- **Dependencies:** ✅ Ensure route patterns provide equivalent functionality
 
-1. Completely remove all domain-based code
-2. Not provide any migration utilities in the codebase
-3. Focus solely on the route-based approach
-4. Document the route-based API as the only supported method
+## Phase 2: Consolidate and Simplify Code
 
-This approach prioritizes codebase clarity over backward compatibility, which is appropriate since we've already made a clean break in the public API with v14.0.0.
+### 2.1 Streamline Interface Definitions ✅
 
-## File Changes
+There are several redundant interfaces that could be simplified.
 
-### Files to Delete (Remove Completely)
-- [x] `/ts/forwarding/config/domain-config.ts` - Deleted with no replacement
-- [x] `/ts/forwarding/config/domain-manager.ts` - Deleted with no replacement
-- [x] `/ts/forwarding/config/forwarding-types.ts` - Updated with pure route-based types
-- [x] Any domain-config related tests have been updated to use route-based approach
+- **Action:** ✅
+  - ✅ Remove legacy type checking functions (`isLegacyOptions`, `isRoutedOptions`) in `/ts/proxies/smart-proxy/models/interfaces.ts`
+  - ✅ Update `ISmartProxyOptions` interface to remove obsolete properties
+  - ✅ Remove backward compatibility aliases like `IRoutedSmartProxyOptions`
+- **Impact:** Medium - May break code that relies on these interfaces
+- **Dependencies:** ✅ Update any code that references these interfaces
 
-### Files to Modify (Remove All Domain References)
-- [x] `/ts/certificate/providers/cert-provisioner.ts` - Complete rewrite to use routes only ✅
-- [x] `/ts/proxies/smart-proxy/network-proxy-bridge.ts` - Direct route processing implementation ✅
-- [x] `/ts/certificate/models/certificate-types.ts` - Updated with route-based interfaces ✅
-- [x] `/ts/certificate/index.ts` - Cleaned up domain-related types and exports
-- [x] `/ts/http/port80/port80-handler.ts` - Updated to work exclusively with routes
-- [x] `/ts/proxies/smart-proxy/smart-proxy.ts` - Removed domain references
-- [x] `test/test.forwarding.ts` - Updated to use route-based approach
-- [x] `test/test.forwarding.unit.ts` - Updated to use route-based approach
+### 2.2 Consolidate Route Utilities
 
-### New Files to Create (Route-Focused)
-- [x] `/ts/proxies/smart-proxy/utils/route-helpers.ts` - Created with helper functions for common route configurations
-- [x] `/ts/proxies/smart-proxy/utils/route-migration-utils.ts` - Added migration utilities from domains to routes
-- [x] `/ts/proxies/smart-proxy/utils/route-validators.ts` - Validation utilities for route configurations
-- [x] `/ts/proxies/smart-proxy/utils/route-utils.ts` - Additional route utility functions
-- [x] `/ts/proxies/smart-proxy/utils/route-patterns.ts` - Common route patterns for easy configuration
-- [x] `/ts/proxies/smart-proxy/utils/index.ts` - Central export point for all route utilities
+The route utilities are spread across multiple files with some overlapping functionality.

+
+# Remove the export from the index file
+# Edit ts/proxies/smart-proxy/utils/index.ts to remove the export line
+```
+
+### 2. Clean Up References to Deleted Files
+
+```bash
+# Update forwarding-types.ts to remove imports from route-helpers.js
+# Edit ts/forwarding/config/forwarding-types.ts
+
+# Remove or update imports in index.ts
+# Edit ts/proxies/smart-proxy/utils/index.ts
+```
+
+### 3. Remove Deprecated Forwarding Types
+
+```bash

+Ensure all IP matching functions consistently handle IPv6-mapped IPv4 addresses:
+
+```typescript
+// In all IP matching functions:
+const normalizeIp = (ip: string): string => {
+  return ip.startsWith('::ffff:') ? ip.substring(7) : ip;
+};
+```
+
+## Implementation Results ✅
+
+The cleanup implementation was successful, resulting in:
+
