# 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[];
|
||||

}
|
||||
|

return result;
|

} else if ('from' in ports && 'to' in ports) {
|
||||
return { from: ports.from, to: ports.to };
|
||||
}
|
||||
|
||||
// Fallback
|
||||
return 80;
|
||||
}
|
||||
|
||||
/**
|
||||
* Get status of all managed rules
|
||||
*/
|
||||
public async getStatus(): Promise<Record<string, NfTablesStatus>> {
|
||||
const result: Record<string, NfTablesStatus> = {};
|
||||
|
||||
for (const [routeId, proxy] of this.rulesMap.entries()) {
|
||||
result[routeId] = await proxy.getStatus();
|
||||
}
|
||||
|
||||
return result;
|
||||
}
|
||||
|
||||
/**
|
||||
* Stop all NFTables rules
|
||||
*/
|
||||
public async stop(): Promise<void> {
|
||||
// Stop all NFTables proxies
|
||||
const stopPromises = Array.from(this.rulesMap.values()).map(proxy => proxy.stop());
|
||||
await Promise.all(stopPromises);
|
||||
|
||||
this.rulesMap.clear();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
This duplication with inconsistent naming (`allowedIps` vs `ipAllowList` and `blockedIps` vs `ipBlockList`) caused routing issues when IP security checks were used, particularly with port range configurations.
|
||||
### Phase 3: SmartProxy Integration
|
||||
|
||||
## Implementation Plan (COMPLETED)
|
||||
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.
|
||||
|
||||
### Phase 1: Interface Consolidation ✅
|
||||
2. **Implementation**:
|
||||
```typescript
|
||||
// In ts/proxies/smart-proxy/smart-proxy.ts
|
||||
import { NFTablesManager } from './nftables-manager.js';
|
||||
|
||||
1. **Create a unified interface definition:** ✅
|
||||
- Created one comprehensive `IRouteSecurity` interface that includes all properties
|
||||
- Standardized on `ipAllowList` and `ipBlockList` property names
|
||||
- Added proper documentation for each property
|
||||
- Removed the duplicate interface definition
|
||||
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();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 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
|
||||

```
|
||||
|
||||
### Phase 2: Code and Documentation Updates ✅
|
||||
### Phase 6: Documentation and Testing
|
||||
|
||||
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**:
|
||||

|
||||
- 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
|
||||
// In test/test.nftables-integration.ts
|
||||
import { SmartProxy } from '../ts/proxies/smart-proxy/index.js';

|
||||
}, {
|
||||
ports: PROXY_PORT,
|
||||

|
||||
})
|
||||
]
|

});
|
||||
|

|
||||
// Start the proxy
|

await smartProxy.start();
|
||||
});
|
||||
|
||||
tap.test('should forward TCP connections through NFTables', async () => {

const client = new net.Socket();
|
||||
|
||||
// Authentication methods
|
||||
basicAuth?: {
|

});
|
||||
|
||||
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();
|
||||
```
|
||||
|
||||
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.
