+# 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.

-# SmartProxy Configuration Troubleshooting
+# NFTables-SmartProxy Integration Plan
 
-## IPv6/IPv4 Mapping Issue
+## Overview
 
-### Problem Identified
-The SmartProxy is failing to match connections for wildcard domains (like `*.lossless.digital`) when IP restrictions are in place. After extensive debugging, the root cause has been identified:
+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.
 
-When a connection comes in from an IPv4 address (e.g., `212.95.99.130`), the Node.js server receives it as an IPv6-mapped IPv4 address with the format `::ffff:212.95.99.130`. However, the route configuration is expecting the exact string `212.95.99.130`, causing a mismatch.
+## Current State
 
-From the debug logs:
-```
-[DEBUG] Route rejected: clientIp mismatch. Request: ::ffff:212.95.99.130, Route patterns: ["212.95.99.130"]
-```
+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.
 
-### Solution
+## Goals
 
-To fix this issue, update the route configurations to include both formats of the IP address. Here's how to modify the affected route:
+1. Create a unified configuration system where SmartProxy routes can specify NFTables-based forwarding.
+2. Allow SmartProxy to dynamically provision and manage NFTables rules based on route configuration.
+3. Support advanced filtering and security rules through NFTables for better performance.
+4. Ensure backward compatibility with existing setups.
+5. Provide metrics integration between the systems.
 
-```typescript
-// Wildcard domain route for *.lossless.digital
-{
-  match: {
-    ports: 443,
-    domains: ['*.lossless.digital'],
-    clientIp: ['212.95.99.130', '::ffff:212.95.99.130'],  // Include both formats
-  },
-  action: {
-    type: 'forward',
-    target: {
-      host: '212.95.99.130',
-      port: 443
-    },
-    tls: {
-      mode: 'passthrough'
-    },
-    security: {
-      allowedIps: ['212.95.99.130', '::ffff:212.95.99.130']  // Include both formats
-    }
-  },
-  name: 'Wildcard lossless.digital route (IP restricted)'
-}
-```
+## Implementation Plan
 
-### Alternative Long-Term Fix
+### Phase 1: Route Configuration Schema Extension
 
-A more robust solution would be to modify the SmartProxy codebase to automatically handle IPv6-mapped IPv4 addresses by normalizing them before comparison. This would involve:
+1. **Extend Route Configuration Schema**:
+   - Add new `forwardingEngine` option to IRouteAction to specify the forwarding implementation.
+   - Support values: 'node' (current NodeJS implementation) and 'nftables' (Linux NFTables).
+   - Add NFTables-specific configuration options to IRouteAction.
 
-1. Modifying the `matchIpPattern` function in `route-manager.ts` to normalize IPv6-mapped IPv4 addresses:
+2. **Update Type Definitions**:
+   ```typescript
+   // In route-types.ts
+   export interface IRouteAction {
+     type: 'forward' | 'redirect' | 'block';
+     target?: IRouteTarget;
+     security?: IRouteSecurity;
+     options?: IRouteOptions;
+     tls?: IRouteTlsOptions;
+     forwardingEngine?: 'node' | 'nftables';  // New field
+     nftables?: INfTablesOptions;             // New field
+   }
 
-```typescript
-private matchIpPattern(pattern: string, ip: string): boolean {
-  // Normalize IPv6-mapped IPv4 addresses
-  const normalizedIp = ip.startsWith('::ffff:') ? ip.substring(7) : ip;
-  const normalizedPattern = pattern.startsWith('::ffff:') ? pattern.substring(7) : pattern;
-  
-  // Handle exact match with normalized addresses
-  if (normalizedPattern === normalizedIp) {
-    return true;
-  }
-  
-  // Rest of the existing function...
-}
-```
-
-2. Making similar modifications to other IP-related functions in the codebase.
-
-## Wild Card Domain Matching Issue
-
-### Explanation
-
-The wildcard domain matching in SmartProxy works as follows:
-
-1. When a pattern like `*.lossless.digital` is specified, it's converted to a regex: `/^.*\.lossless\.digital$/i`
-2. This correctly matches any subdomain like `my.lossless.digital`, `api.lossless.digital`, etc.
-3. However, it does NOT match the apex domain `lossless.digital` (without a subdomain)
-
-If you need to match both the apex domain and subdomains, use a list:
-```typescript
-domains: ['lossless.digital', '*.lossless.digital']
-```
-
-## Debugging SmartProxy
-
-To debug routing issues in SmartProxy:
-
-1. Add detailed logging to the `route-manager.js` file in the `dist_ts` directory:
-   - `findMatchingRoute` method - to see what criteria are being checked
-   - `matchRouteDomain` method - to see domain matching logic
-   - `matchDomain` method - to see pattern matching
-   - `matchIpPattern` method - to see IP matching logic
-
-2. Run the proxy with debugging enabled:
-   ```
-   pnpm run startNew
+   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
+   }
    ```
 
-3. Monitor the logs for detailed information about the routing process and identify where matches are failing.
+### Phase 2: NFTablesManager Implementation
 
-## Priority and Route Order
+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.
 
-Remember that routes are evaluated in priority order (higher priority first). If multiple routes could match the same request, ensure that the more specific routes have higher priority.
+2. **Implementation**:
+   ```typescript
+   // In ts/proxies/smart-proxy/nftables-manager.ts
+   export class NFTablesManager {
+     private rulesMap: Map<string, NfTablesProxy> = new Map();

-When routes have the same priority (or none specified), they're evaluated in the order they're defined in the configuration.
+### Phase 3: SmartProxy Integration
+
+1. **Extend SmartProxy Class**:
+   - Add NFTablesManager as a property of SmartProxy.
+   - Hook into route configuration to provision NFTables rules.
+   - Add methods to manage NFTables functionality.
+
+2. **Implementation**:
+   ```typescript
+   // In ts/proxies/smart-proxy/smart-proxy.ts
+   import { NFTablesManager } from './nftables-manager.js';
+
+   export class SmartProxy {
+     // Existing properties
+     private nftablesManager: NFTablesManager;
+     
+     constructor(options: ISmartProxyOptions) {
+       // Existing initialization
+       
+       // Initialize NFTablesManager
+       this.nftablesManager = new NFTablesManager(options);
+     }
+     
+     /**
+      * Start the SmartProxy server
+      */
+     public async start(): Promise<void> {
+       // Existing initialization
+       
+       // If we have routes, provision NFTables rules for them
+       for (const route of this.settings.routes) {
+         if (route.action.forwardingEngine === 'nftables') {
+           await this.nftablesManager.provisionRoute(route);
+         }
+       }
+       
+       // Rest of existing start method
+     }
+     
+     /**
+      * Stop the SmartProxy server
+      */
+     public async stop(): Promise<void> {
+       // Stop NFTablesManager first
+       await this.nftablesManager.stop();
+       
+       // Rest of existing stop method
+     }
+     
+     /**
+      * Update routes
+      */
+     public async updateRoutes(routes: IRouteConfig[]): Promise<void> {
+       // Get existing routes that use NFTables
+       const oldNfTablesRoutes = this.settings.routes.filter(
+         r => r.action.forwardingEngine === 'nftables'
+       );
+       
+       // Get new routes that use NFTables
+       const newNfTablesRoutes = routes.filter(
+         r => r.action.forwardingEngine === 'nftables'
+       );
+       
+       // Find routes to remove, update, or add
+       for (const oldRoute of oldNfTablesRoutes) {
+         const newRoute = newNfTablesRoutes.find(r => r.name === oldRoute.name);
+         
+         if (!newRoute) {
+           // Route was removed
+           await this.nftablesManager.deprovisionRoute(oldRoute);
+         } else {
+           // Route was updated
+           await this.nftablesManager.updateRoute(oldRoute, newRoute);

+     }
+     
+     /**
+      * Get NFTables status
+      */
+     public async getNfTablesStatus(): Promise<Record<string, NfTablesStatus>> {
+       return this.nftablesManager.getStatus();
+     }
+   }
+   ```
+
+### Phase 4: Routing System Integration
+
+1. **Extend the Route-Connection-Handler**:
+   - Modify to check if a route uses NFTables.
+   - Skip Node.js-based connection handling for NFTables routes.
+
+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
+     }
+   }
+   ```
+
+### Phase 5: CLI and Configuration Helpers
+
+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(
+     nameOrDomains: string | string[],
+     target: { host: string; port: number | 'preserve' },
+     options: {
+       ports?: TPortRange;
+       protocol?: 'tcp' | 'udp' | 'all';
+       preserveSourceIP?: boolean;
+       allowedIps?: string[];
+       maxRate?: string;
+       priority?: number;
+       useTls?: boolean;
+     } = {}
+   ): IRouteConfig {
+     // Determine if this is a name or domain
+     let name: string;
+     let domains: string | string[];
+     
+     if (Array.isArray(nameOrDomains) || nameOrDomains.includes('.')) {
+       domains = nameOrDomains;
+       name = Array.isArray(nameOrDomains) ? nameOrDomains[0] : nameOrDomains;
+     } else {
+       name = nameOrDomains;
+       domains = []; // No domains
+     }
+     
+     const route: IRouteConfig = {
+       name,
+       match: {
+         domains,
+         ports: options.ports || 80
+       },
+       action: {
+         type: 'forward',
+         target: {
+           host: target.host,
+           port: target.port
+         },
+         forwardingEngine: 'nftables',
+         nftables: {
+           protocol: options.protocol || 'tcp',
+           preserveSourceIP: options.preserveSourceIP,
+           maxRate: options.maxRate,
+           priority: options.priority
+         }
+       }
+     };
+     
+     // Add security if allowed IPs are specified
+     if (options.allowedIps?.length) {
+       route.action.security = {
+         ipAllowList: options.allowedIps
+       };
+     }
+     
+     // Add TLS options if needed
+     if (options.useTls) {
+       route.action.tls = {
+         mode: 'passthrough'
+       };
+     }
+     
+     return route;
+   }
+   
+   /**
+    * Create an NFTables-based TLS termination route
+    */
+   export function createNfTablesTerminateRoute(
+     nameOrDomains: string | string[],
+     target: { host: string; port: number | 'preserve' },
+     options: {
+       ports?: TPortRange;
+       protocol?: 'tcp' | 'udp' | 'all';
+       preserveSourceIP?: boolean;
+       allowedIps?: string[];
+       maxRate?: string;
+       priority?: number;
+       certificate?: string | { cert: string; key: string };
+     } = {}
+   ): IRouteConfig {
+     const route = createNfTablesRoute(
+       nameOrDomains,
+       target,
+       {
+         ...options,
+         ports: options.ports || 443,
+         useTls: false
+       }
+     );
+     
+     // Set TLS termination
+     route.action.tls = {
+       mode: 'terminate',
+       certificate: options.certificate || 'auto'
+     };
+     
+     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.
+
+```typescript
+// In test/test.nftables-integration.ts

+      }, {
+        ports: PROXY_PORT,
+        protocol: 'tcp'
+      })
+    ]
+  });
+  
+  // Start the proxy
+  await smartProxy.start();
+});
+
+tap.test('should forward TCP connections through NFTables', async () => {

+    });
+

+  await new Promise<void>((resolve) => {
+    testServer.close(() => {
+      resolve();
+    });
+  });
+});
+
+export default tap.start();
+```
+
+## 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.
