 # Changelog
 
+## 2025-05-15 - 18.1.1 - fix(network-proxy/websocket)
+Improve WebSocket connection closure and update router integration
+
+- Wrap WS close logic in try-catch blocks to ensure valid close codes are used for both incoming and outgoing WebSocket connections
+- Use explicit numeric close codes (defaulting to 1000 when unavailable) to prevent improper socket termination
+- Update NetworkProxy updateRoutes to also refresh the WebSocket handler routes for consistent configuration
+
+## 2025-05-15 - 18.1.0 - feat(nftables)
+Add NFTables integration for kernel-level forwarding and update documentation, tests, and helper functions
+
+- Bump dependency versions in package.json (e.g. @git.zone/tsbuild and @git.zone/tstest)
+- Document NFTables integration in README with examples for createNfTablesRoute and createNfTablesTerminateRoute
+- Update Quick Start guide to reference NFTables and new helper functions
+- Add new helper functions for NFTables-based routes and update migration instructions
+- Adjust tests to accommodate NFTables integration and updated route configurations
+
+## 2025-05-15 - 18.0.2 - fix(smartproxy)
+Update project documentation and internal configuration files; no functional changes.
+
+- Synchronized readme, hints, and configuration metadata with current implementation
+- Updated tests and commit info details to reflect project structure
+
 ## 2025-05-15 - 18.0.1 - fix(smartproxy)
 Consolidate duplicate IRouteSecurity interfaces to use standardized property names (ipAllowList and ipBlockList), fix port preservation logic for 'preserve' mode in forward actions, and update dependency versions in package.json.

-## 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

-# SmartProxy Interface Consolidation Plan
+# NFTables-SmartProxy Integration Plan
 
 ## Overview
 
-This document outlines a plan to consolidate duplicate and inconsistent interfaces in the SmartProxy codebase, specifically the `IRouteSecurity` interface which is defined twice with different properties. This inconsistency caused issues with security checks for port forwarding. The goal is to unify these interfaces, use consistent property naming, and improve code maintainability.
+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.
 
-## Problem Description (RESOLVED)
+## Current State
 
-We had two separate `IRouteSecurity` interfaces defined in `ts/proxies/smart-proxy/models/route-types.ts` which have now been consolidated into a single interface:
+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.
 
-1. **First definition** (previous lines 116-122) - Used in IRouteAction:
+## Goals
+
+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.
+
+## Implementation Plan
+
+### Phase 1: Route Configuration Schema Extension
+
+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.
+
+2. **Update Type Definitions**:
    ```typescript
-   export interface IRouteSecurity {
-     allowedIps?: string[];
-     blockedIps?: string[];
-     maxConnections?: number;
-     authentication?: IRouteAuthentication;
+   // 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
+   }
+
+   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
    }
    ```
 
-2. **Second definition** (previous lines 253-272) - Used directly in IRouteConfig:
+### Phase 2: NFTablesManager Implementation
+
+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.
+
+2. **Implementation**:
    ```typescript
-   export interface IRouteSecurity {
-     rateLimit?: IRouteRateLimit;
-     basicAuth?: {...};
-     jwtAuth?: {...};
-     ipAllowList?: string[];
-     ipBlockList?: string[];

+     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
    
-2. **Update references to use the unified interface:** ✅
-   - Updated all code that references the old interface properties
-   - Updated all configurations to use the new property names
-   - Ensured implementation in `route-manager.ts` uses the correct property names
+   /**
+    * Create an NFTables-based route
+    */
+   export function createNfTablesRoute(

+     return route;
+   }
+   
+   /**

+     } = {}
+   ): IRouteConfig {
+     const route = createNfTablesRoute(
+       nameOrDomains,
+       target,
+       {
+         ...options,
+         ports: options.ports || 443,
+         useTls: false
+       }
+     );
+     
+     // Set TLS termination

+       certificate: options.certificate || 'auto'
+     };
+     
+     return route;
+   }
+   ```

-1. **Update type usages and documentation:** ✅
-   - Updated all code that creates or uses security configurations
-   - Updated documentation to reflect the new interface structure
-   - Added examples of the correct property usage
-   - Documented the changes in this plan
+1. **Update Documentation**:
+   - Add NFTables integration documentation to README and API docs.
+   - Document the implementation and use cases.
 
-2. **Fix TypeScript errors:** ✅
-   - Fixed TypeScript errors in http-request-handler.ts
-   - Successfully built the project with `pnpm run build`
+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.
 
-## Implementation Completed ✅
-
-The interface consolidation has been successfully implemented with the following changes:
-
-1. **Unified interface created:**
 ```typescript
-// Consolidated interface definition
-export interface IRouteSecurity {
-  // Access control lists
-  ipAllowList?: string[];        // IP addresses that are allowed to connect
-  ipBlockList?: string[];        // IP addresses that are blocked from connecting

+      resolve();
+    });
+  });

+
+export default tap.start();
 ```
 
-2. **Updated isClientIpAllowed method:**
-```typescript
-private isClientIpAllowed(route: IRouteConfig, clientIp: string): boolean {
-  const security = route.action.security;
-  
-  if (!security) {
-    return true; // No security settings means allowed
-  }
-  
-  // Check blocked IPs first
-  if (security.ipBlockList && security.ipBlockList.length > 0) {
-    for (const pattern of security.ipBlockList) {
-      if (this.matchIpPattern(pattern, clientIp)) {
-        return false; // IP is blocked
-      }
-    }
-  }
-  
-  // If there are allowed IPs, check them
-  if (security.ipAllowList && security.ipAllowList.length > 0) {
-    for (const pattern of security.ipAllowList) {
-      if (this.matchIpPattern(pattern, clientIp)) {
-        return true; // IP is allowed
-      }
-    }
-    return false; // IP not in allowed list
-  }
-  
-  // No allowed IPs specified, so IP is allowed
-  return true;
-}
-```
+## Expected Benefits
 
-3. **Fixed port preservation logic:**
-```typescript
-// In base-handler.ts
-protected resolvePort(
-  port: number | 'preserve' | ((ctx: any) => number), 
-  incomingPort: number = 80
-): number {
-  if (typeof port === 'function') {
-    try {
-      // Create a minimal context for the function that includes the incoming port
-      const ctx = { port: incomingPort };
-      return port(ctx);
-    } catch (err) {
-      console.error('Error resolving port function:', err);
-      return incomingPort; // Fall back to incoming port
-    }
-  } else if (port === 'preserve') {
-    return incomingPort; // Use the actual incoming port for 'preserve'
-  } else {
-    return port;
-  }
-}
-```
+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.
 
-4. **Fixed TypeScript error in http-request-handler.ts:**
-```typescript
-// Safely check for host property existence 
-if (options.headers && 'host' in options.headers) {
-  // Only apply if host header rewrite is enabled or not explicitly disabled
-  const shouldRewriteHost = route?.action.options?.rewriteHostHeader !== false;
-  if (shouldRewriteHost) {
-    // Safely cast to OutgoingHttpHeaders to access host property
-    (options.headers as plugins.http.OutgoingHttpHeaders).host = `${destination.host}:${destination.port}`;
-  }
-}
-```
+## Implementation Notes
 
-## Achieved Benefits ✅
+- 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.
 
-- **Improved Consistency**: Single, unified interface with consistent property naming
-- **Better Type Safety**: Eliminated confusing duplicate interface definitions
-- **Reduced Errors**: Prevented misunderstandings about which property names to use
-- **Forward Compatibility**: Clearer path for future security enhancements
-- **Better Developer Experience**: Simplified interface with comprehensive documentation
-- **Fixed Issues**: Port preservation with port ranges now works correctly with security checks
+## Timeline
 
-## Verification ✅
+- 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
 
-- The project builds successfully with `pnpm run build`
-- The unified interface works properly with all type checking
-- The port range forwarding with `port: 'preserve'` now works correctly with IP security rules
-- The security checks consistently use the standardized property names throughout the codebase
+**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.
