 # Changelog

+## 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.
+
+- Unified the duplicate IRouteSecurity interfaces into a single definition using ipAllowList and ipBlockList.
+- Updated security checks (e.g. isClientIpAllowed) to use the new standardized property names.
+- Fixed the resolvePort function to properly handle 'preserve' mode and function-based port mapping.
+- Bumped dependency versions: @push.rocks/smartacme from 7.3.2 to 7.3.3 and @types/node to 22.15.18, and updated tsbuild from 2.3.2 to 2.4.1.
+- Revised documentation and changelog to reflect the interface consolidation and bug fixes.
+
+## 2025-05-15 - 18.0.0 - BREAKING CHANGE(IRouteSecurity)
+Consolidate duplicated IRouteSecurity interfaces by unifying property names (using 'ipAllowList' and 'ipBlockList' exclusively) and removing legacy definitions, updating security checks throughout the codebase to handle IPv6-mapped IPv4 addresses and cleaning up deprecated forwarding helpers.
+
+- Unified duplicate IRouteSecurity definitions into a single interface with consistent property names.
+- Replaced 'allowedIps' and 'blockedIps' with 'ipAllowList' and 'ipBlockList' respectively.
+- Updated references in security and route managers to use the new properties.
+- Ensured consistent IPv6-mapped IPv4 normalization in IP security checks.
+- Removed deprecated helpers and legacy code affecting port forwarding and route migration.
+
 ## 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

-# SmartProxy Codebase Cleanup Plan
+# NFTables-SmartProxy Integration Plan

 ## Overview

-This document outlines a comprehensive plan to clean up the SmartProxy codebase by removing deprecated and unused code, consolidating functionality, and reducing complexity. The goal is to make the codebase more maintainable, easier to understand, and better positioned for future enhancements.
+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.

-## Phase 1: Remove Deprecated Code
+## Current State

-### 1.1 Delete Legacy Migration Utilities ✅
+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.

-The route migration utilities were created to assist in transitioning from the legacy domain-based configuration to the new route-based configuration system. As this migration is now complete, these utilities can be safely removed.
+## Goals

- **Action:** ✅ Remove `/ts/proxies/smart-proxy/utils/route-migration-utils.ts`
- **Impact:** Low - This file is explicitly marked as temporary and for migration purposes only
- **Dependencies:** ✅ Update any imports of these utilities (check forwarding-types.ts)
+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.

-### 1.2 Clean Up References to Deleted Files ✅
+## Implementation Plan

-Several files are marked for deletion in the git status but are still referenced in the codebase.
+### Phase 1: Route Configuration Schema Extension

- **Action:** ✅ Remove references to deleted route-helpers files:
-  - ✅ Update `/ts/proxies/smart-proxy/utils/index.ts` to remove `export * from './route-helpers.js';`
-  - ✅ Update `/ts/forwarding/config/forwarding-types.ts` to remove imports and re-exports of route helper functions
- **Impact:** Medium - May break code that still relies on these helpers
- **Dependencies:** ✅ Ensure route-patterns.js provides equivalent functionality (moved helper functions from route-helpers.js to route-patterns.ts)
+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.

-### 1.3 Remove Deprecated Forwarding Types and Helpers ✅
+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
+   }

-Legacy forwarding types and helper functions in forwarding-types.ts are marked as deprecated.
+   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
+   }
+   ```

- **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
+### Phase 2: NFTablesManager Implementation

-## Phase 2: Consolidate and Simplify Code
+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.

-### 2.1 Streamline Interface Definitions ✅
+2. **Implementation**:
+   ```typescript
+   // In ts/proxies/smart-proxy/nftables-manager.ts
+   export class NFTablesManager {
+     private rulesMap: Map<string, NfTablesProxy> = new Map();
+

-There are several redundant interfaces that could be simplified.
+### Phase 3: SmartProxy Integration

- **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
+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.

-### 2.2 Consolidate Route Utilities
+2. **Implementation**:
+   ```typescript
+   // In ts/proxies/smart-proxy/smart-proxy.ts
+   import { NFTablesManager } from './nftables-manager.js';

-The route utilities are spread across multiple files with some overlapping functionality.
+   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);
+         }
+       }
+       
+       // Find new routes to add
+       for (const newRoute of newNfTablesRoutes) {
+         const oldRoute = oldNfTablesRoutes.find(r => r.name === newRoute.name);
+         
+         if (!oldRoute) {
+           // New route
+           await this.nftablesManager.provisionRoute(newRoute);
+         }
+       }
+       
+       // Update settings with the new routes
+       this.settings.routes = routes;
+       
+       // Update route manager with new routes
+       this.routeManager.updateRoutes(routes);
+     }
+     
+     /**
+      * Get NFTables status
+      */
+     public async getNfTablesStatus(): Promise<Record<string, NfTablesStatus>> {
+       return this.nftablesManager.getStatus();
+     }
+   }
+   ```

- **Action:**
-  - Consolidate route utilities into a single coherent structure
-  - Move common functions from route-utils.ts, route-patterns.ts into a single location
-  - Ensure consistent naming conventions for route utility functions
- **Impact:** Medium - Requires careful refactoring
- **Dependencies:** Update all references to these utilities
+### Phase 4: Routing System Integration

-### 2.3 Clean Up Legacy Connection Handling ✅
+1. **Extend the Route-Connection-Handler**:
+   - Modify to check if a route uses NFTables.
+   - Skip Node.js-based connection handling for NFTables routes.

-The route-connection-handler.ts file contains legacy code and parameters kept for backward compatibility.
+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
+     }
+   }
+   ```

- **Action:** ✅
-  - ✅ Remove unused parameters and legacy comments from `setupDirectConnection` method
-  - ✅ Simplify connection handling logic by removing special cases for legacy configurations
- **Impact:** Medium - Requires careful testing to ensure no regressions
- **Dependencies:** ✅ Test with all current route configurations
+### Phase 5: CLI and Configuration Helpers

-## Phase 3: Code Modernization
+1. **Add Helper Functions**:
+   - Create helper functions for easy route creation with NFTables.
+   - Update the route-helpers.ts utility file.

-### 3.1 Standardize on 'preserve' Port Handling ✅
+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: {

+       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

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

-Previously implemented changes to use `port: 'preserve'` instead of `preservePort: true` should be consistently applied.
+### Phase 6: Documentation and Testing

-
-## Detailed Implementation Steps
-
-### 1. Remove Legacy Migration Utilities
-
-```bash
-# Delete the file
-git rm ts/proxies/smart-proxy/utils/route-migration-utils.ts
-
-# 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
-# Edit ts/forwarding/config/forwarding-types.ts to remove deprecated helpers and interfaces
-```
-
-### 4. Streamline Interface Definitions
-
-```bash
-# Edit ts/proxies/smart-proxy/models/interfaces.ts to remove legacy functions and aliases
-```
-
-### 5. Normalize IPv6-Mapped IPv4 Addresses
-
-Ensure all IP matching functions consistently handle IPv6-mapped IPv4 addresses:
+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 all IP matching functions:
-const normalizeIp = (ip: string): string => {
-  return ip.startsWith('::ffff:') ? ip.substring(7) : ip;
-};
+// In test/test.nftables-integration.ts
+import { SmartProxy } from '../ts/proxies/smart-proxy/index.js';
+import { createNfTablesRoute } from '../ts/proxies/smart-proxy/utils/route-helpers.js';
+import { expect, tap } from '@push.rocks/tapbundle';
+import * as net from 'net';
+
+// Test server and client utilities
+let testServer: net.Server;
+let smartProxy: SmartProxy;
+
+const TEST_PORT = 4000;
+const PROXY_PORT = 5000;
+const TEST_DATA = 'Hello through NFTables!';
+
+tap.test('setup NFTables integration test environment', async () => {
+  // Create a test TCP server
+  testServer = net.createServer((socket) => {
+    socket.on('data', (data) => {
+      socket.write(`Server says: ${data.toString()}`);
+    });
+  });
+  
+  await new Promise<void>((resolve) => {
+    testServer.listen(TEST_PORT, () => {
+      console.log(`Test server listening on port ${TEST_PORT}`);
+      resolve();
+    });
+  });
+  
+  // Create SmartProxy with NFTables route
+  smartProxy = new SmartProxy({
+    routes: [
+      createNfTablesRoute('test-nftables', {
+        host: 'localhost',
+        port: TEST_PORT
+      }, {
+        ports: PROXY_PORT,
+        protocol: 'tcp'
+      })
+    ]
+  });
+  
+  // Start the proxy
+  await smartProxy.start();
+});
+
+tap.test('should forward TCP connections through NFTables', async () => {
+  // Connect to the proxy port
+  const client = new net.Socket();
+  
+  const response = await new Promise<string>((resolve, reject) => {
+    let responseData = '';
+    
+    client.connect(PROXY_PORT, 'localhost', () => {
+      client.write(TEST_DATA);
+    });
+    
+    client.on('data', (data) => {
+      responseData += data.toString();
+      client.end();
+    });
+    
+    client.on('end', () => {
+      resolve(responseData);
+    });
+    
+    client.on('error', (err) => {
+      reject(err);
+    });
+  });
+  
+  expect(response).toEqual(`Server says: ${TEST_DATA}`);
+});
+
+tap.test('cleanup NFTables integration test environment', async () => {
+  // Stop the proxy and test server
+  await smartProxy.stop();
+  
+  await new Promise<void>((resolve) => {
+    testServer.close(() => {
+      resolve();
+    });
+  });
+});
+
+export default tap.start();
 ```

-## Implementation Results ✅
+## Expected Benefits

-The cleanup implementation was successful, resulting in:
+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.

- **Reduced Codebase Size**: Successfully removed multiple deprecated files and functions
- **Improved Maintainability**: Cleaner, more focused code without legacy compatibility layers
- **Reduced Complexity**: Eliminated special cases for legacy config formats
- **Better Developer Experience**: Standardized on consistent patterns for port handling
- **Future-Proofing**: Removed deprecated code that would complicate future upgrades
- **Type Safety**: Fixed multiple TypeScript errors and improved type checking
+## Implementation Notes

-All changes successfully compile and the build process passes with no errors. The codebase is now simpler, more maintainable, and better positioned for future enhancements.
+- 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.
