+# 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, /* ... */ },
+    // ...
+  }
+];
+```

-## Migration to v16.0.0
+## NFTables Integration
 
-Version 16.0.0 completes the migration to a fully unified route-based configuration system with improved helper functions:
+SmartProxy v18.0.0 includes full integration with Linux NFTables for high-performance kernel-level packet forwarding. NFTables operates directly in the Linux kernel, providing much better performance than user-space proxying for high-traffic scenarios.
+
+### When to Use NFTables
+
+NFTables routing is ideal for:
+- High-traffic TCP/UDP forwarding where performance is critical
+- Port forwarding scenarios where you need minimal latency
+- Load balancing across multiple backend servers
+- Security filtering with IP allowlists/blocklists at kernel level
+
+### Requirements
+
+NFTables support requires:
+- Linux operating system with NFTables installed
+- Root or sudo permissions to configure NFTables rules
+- NFTables kernel modules loaded
+
+### NFTables Route Configuration
+
+Use the NFTables helper functions to create high-performance routes:
+
+```typescript
+import { SmartProxy, createNfTablesRoute, createNfTablesTerminateRoute } from '@push.rocks/smartproxy';
+
+const proxy = new SmartProxy({
+  routes: [
+    // Basic TCP forwarding with NFTables
+    createNfTablesRoute('tcp-forward', {
+      host: 'backend-server',
+      port: 8080
+    }, {
+      ports: 80,
+      protocol: 'tcp'
+    }),
+
+    // NFTables with IP filtering
+    createNfTablesRoute('secure-tcp', {
+      host: 'secure-backend',
+      port: 8443
+    }, {
+      ports: 443,
+      ipAllowList: ['10.0.0.*', '192.168.1.*'],
+      preserveSourceIP: true
+    }),
+
+    // NFTables with QoS (rate limiting)
+    createNfTablesRoute('limited-service', {
+      host: 'api-server',
+      port: 3000
+    }, {
+      ports: 8080,
+      maxRate: '50mbps',
+      priority: 1
+    }),
+
+    // NFTables TLS termination
+    createNfTablesTerminateRoute('https-nftables', {
+      host: 'backend',
+      port: 8080
+    }, {
+      ports: 443,
+      certificate: 'auto',
+      useAdvancedNAT: true
+    })
+  ]
+});
+
+await proxy.start();
+```
+
+### NFTables Route Options
+
+The NFTables integration supports these options:
+
+- `protocol`: 'tcp' | 'udp' | 'all' - Protocol to forward
+- `preserveSourceIP`: boolean - Preserve client IP for backend
+- `ipAllowList`: string[] - Allow only these IPs (glob patterns)
+- `ipBlockList`: string[] - Block these IPs (glob patterns)
+- `maxRate`: string - Rate limit (e.g., '100mbps', '1gbps')
+- `priority`: number - QoS priority level
+- `tableName`: string - Custom NFTables table name
+- `useIPSets`: boolean - Use IP sets for better performance
+- `useAdvancedNAT`: boolean - Enable connection tracking
+
+### NFTables Status Monitoring
+
+You can monitor the status of NFTables rules:
+
+```typescript
+// Get status of all NFTables rules
+const nftStatus = await proxy.getNfTablesStatus();
+
+// Status includes:
+// - active: boolean
+// - ruleCount: { total, added, removed }
+// - packetStats: { forwarded, dropped }
+// - lastUpdate: Date
+```
+
+### Performance Considerations
+
+NFTables provides significantly better performance than application-level proxying:
+- Operates at kernel level with minimal overhead
+- Can handle millions of packets per second
+- Direct packet forwarding without copying to userspace
+- Hardware offload support on compatible network cards
+
+### Limitations
+
+NFTables routing has some limitations:
+- Cannot modify HTTP headers or content
+- Limited to basic NAT and forwarding operations
+- Requires root permissions
+- Linux-only (not available on Windows/macOS)
+- No WebSocket message inspection
+
+For scenarios requiring application-level features (header manipulation, WebSocket handling, etc.), use the standard SmartProxy routes without NFTables.
+
+## Migration to v18.0.0
+
+Version 18.0.0 continues the evolution with NFTables integration while maintaining the unified route-based configuration system:
 
 ### Key Changes
 
-1. **Pure Route-Based API**: The configuration now exclusively uses the match/action pattern with no legacy interfaces
-2. **Improved Helper Functions**: Enhanced helper functions with cleaner parameter signatures
-3. **Removed Legacy Support**: Legacy domain-based APIs have been completely removed
-4. **More Route Pattern Helpers**: Additional helper functions for common routing patterns

-# SmartProxy Complete Route-Based Implementation Plan
+# NFTables-SmartProxy Integration Plan
 
-## Project Goal
-Complete the refactoring of SmartProxy to a pure route-based configuration approach by:
-1. Removing all remaining domain-based configuration code with no backward compatibility
-2. Updating internal components to work directly and exclusively with route configurations
-3. Eliminating all conversion functions and domain-based interfaces
-4. Cleaning up deprecated methods and interfaces completely
-5. Focusing entirely on route-based helper functions for the best developer experience
+## Overview
 
-## Current Status
-The major refactoring to route-based configuration has been successfully completed:
-- SmartProxy now works exclusively with route-based configurations in its public API
-- All test files have been updated to use route-based configurations
-- Documentation has been updated to explain the route-based approach
-- Helper functions have been implemented for creating route configurations
-- All features are working correctly with the new approach
+This document outlines a comprehensive plan to integrate the existing NFTables functionality with the SmartProxy core to provide advanced network-level routing capabilities. The NFTables proxy already exists in the codebase but is not fully integrated with the SmartProxy routing system. This integration will allow SmartProxy to leverage the power of Linux's NFTables firewall system for high-performance port forwarding, load balancing, and security filtering.
 
-### Completed Phases:
-1. ✅ **Phase 1:** CertProvisioner has been fully refactored to work natively with routes
-2. ✅ **Phase 2:** NetworkProxyBridge now works directly with route configurations
-3. ✅ **Phase 3:** Legacy domain configuration code has been removed
-4. ✅ **Phase 4:** Route helpers and configuration experience have been enhanced
-5. ✅ **Phase 5:** Tests and validation have been completed
+## Current State
 
-### Project Status:
-✅ COMPLETED (May 10, 2025): SmartProxy has been fully refactored to a pure route-based configuration approach with no backward compatibility for domain-based configurations.
+1. **NFTablesProxy**: A standalone implementation exists in `ts/proxies/nftables-proxy/` with its own configuration and API.
+2. **SmartProxy**: The main routing system with route-based configuration.
+3. **No Integration**: Currently, these systems operate independently with no shared configuration or coordination.

+   export interface IRouteAction {
+     type: 'forward' | 'redirect' | 'block';
+     target?: IRouteTarget;
+     security?: IRouteSecurity;
+     options?: IRouteOptions;
+     tls?: IRouteTlsOptions;
+     forwardingEngine?: 'node' | 'nftables';  // New field
+     nftables?: INfTablesOptions;             // New field
+   }
 
-## Clean Break Approach
+   export interface INfTablesOptions {
+     preserveSourceIP?: boolean;
+     protocol?: 'tcp' | 'udp' | 'all';
+     maxRate?: string;                // QoS rate limiting
+     priority?: number;               // QoS priority
+     tableName?: string;              // Optional custom table name
+     useIPSets?: boolean;             // Use IP sets for performance
+     useAdvancedNAT?: boolean;        // Use connection tracking
+   }
+   ```
 
-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:
+### Phase 2: NFTablesManager Implementation
 
-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
+1. **Create NFTablesManager Class**:
+   - Create a new class to manage NFTables rules based on SmartProxy routes.
+   - Add methods to create, update, and remove NFTables rules.
+   - Design a rule naming scheme to track which rules correspond to which routes.
 
-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. **Implementation**:
+   ```typescript
+   // In ts/proxies/smart-proxy/nftables-manager.ts
+   export class NFTablesManager {

-   - Easier to maintain and extend
+1. **Extend the Route-Connection-Handler**:
+   - Modify to check if a route uses NFTables.
+   - Skip Node.js-based connection handling for NFTables routes.
 
-2. **Performance Improvements**:
-   - Remove conversion overhead
-   - More efficient route matching
-   - Reduced memory footprint
+2. **Implementation**:
+   ```typescript
+   // In ts/proxies/smart-proxy/route-connection-handler.ts
+   export class RouteConnectionHandler {
+     // Existing methods
+     
+     /**
+      * Route the connection based on match criteria
+      */
+     private routeConnection(
+       socket: plugins.net.Socket, 
+       record: IConnectionRecord,
+       serverName: string,
+       initialChunk?: Buffer
+     ): void {
+       // Find matching route
+       const routeMatch = this.routeManager.findMatchingRoute({
+         port: record.localPort,
+         domain: serverName,
+         clientIp: record.remoteIP,
+         path: undefined,
+         tlsVersion: undefined
+       });
+       
+       if (!routeMatch) {
+         // Existing code for no matching route
+         return;
+       }
+       
+       const route = routeMatch.route;
+       
+       // Check if this route uses NFTables for forwarding
+       if (route.action.forwardingEngine === 'nftables') {
+         // For NFTables routes, we don't need to do anything at the application level
+         // The packet is forwarded at the kernel level
+         
+         // Log the connection
+         console.log(
+           `[${record.id}] Connection forwarded by NFTables: ${record.remoteIP} -> port ${record.localPort}`
+         );
+         
+         // Just close the socket in our application since it's handled at kernel level
+         socket.end();
+         this.connectionManager.initiateCleanupOnce(record, 'nftables_handled');
+         return;
+       }
+       
+       // Existing code for handling the route
+     }
+   }
+   ```
 
-3. **Better Developer Experience**:
-   - Consistent API throughout
-   - Cleaner documentation
-   - More intuitive configuration patterns
+### Phase 5: CLI and Configuration Helpers
 
-4. **Future-Proof Design**:
-   - Clear foundation for new features
-   - Easier to implement advanced routing capabilities
-   - Better integration with modern web patterns
+1. **Add Helper Functions**:
+   - Create helper functions for easy route creation with NFTables.
+   - Update the route-helpers.ts utility file.
+
+2. **Implementation**:
+   ```typescript
+   // In ts/proxies/smart-proxy/utils/route-helpers.ts
+   
+   /**
+    * Create an NFTables-based route
+    */
+   export function createNfTablesRoute(

+     }
+     
+     return route;
+   }
+   
+   /**

+    */
+   export function createNfTablesTerminateRoute(

+     
+     return route;
+   }
+   ```
+
+### Phase 6: Documentation and Testing
+
+1. **Update Documentation**:
+   - Add NFTables integration documentation to README and API docs.
+   - Document the implementation and use cases.
+
+2. **Test Cases**:
+   - Create test cases for NFTables-based routing.
+   - Test performance comparison with Node.js-based forwarding.
+   - Test security features with IP allowlists/blocklists.

+
+## Expected Benefits
+
+1. **Performance**: NFTables operates at the kernel level, offering much higher performance than Node.js-based routing.
+2. **Scalability**: Handle more connections with less CPU and memory usage.
+3. **Security**: Leverage kernel-level security features for better protection.
+4. **Integration**: Unified configuration model between application and network layers.
+5. **Advanced Features**: Support for QoS, rate limiting, and other advanced networking features.
+
+## Implementation Notes
+
+- This integration requires root/sudo access to configure NFTables rules.
+- Consider adding a capability check to gracefully fall back to Node.js routing if NFTables is not available.
+- The NFTables integration should be optional and SmartProxy should continue to work without it.
+- The integration provides a path for future extensions to other kernel-level networking features.
+
+## Timeline
+
+- Phase 1 (Route Configuration Schema): 1-2 days
+- Phase 2 (NFTablesManager): 2-3 days
+- Phase 3 (SmartProxy Integration): 1-2 days
+- Phase 4 (Routing System Integration): 1 day
+- Phase 5 (CLI and Helpers): 1 day
+- Phase 6 (Documentation and Testing): 2 days
+
+**Total Estimated Time: 8-11 days**

+# 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.
