hyper-nat/index.js

Securely tunnel UDP and TCP connections over peer-to-peer networks using hyperswarm for NAT traversal

#!/usr/bin/env node

/**
 * Hyper-NAT - A modern NAT traversal solution using hyperswarm DHT
 * 
 * This is the main entry point that delegates to modularized components:
 * - lib/cli.js - Command line interface and argument parsing
 * - lib/config.js - Configuration management and file handling
 * - lib/modes.js - Client/server mode implementations
 * - lib/dht-relay.js - Core DHT relay functionality for TCP/UDP/TCPUDP
 * - lib/key-utils.js - Key generation and cryptographic utilities
 * 
 * Usage:
 *   node index.js server -p 3000 -s mysecret
 *   node index.js client -l 8080 -r 80 -k <publickey>
 *   node index.js -c config.json
 * 
 * Features:
 * - TCP, UDP, and TCP-over-UDP protocol support
 * - Multi-port configurations with different protocols per port
 * - Configuration file support for complex setups
 * - Automatic key generation and management
 * - Connection timeout and error handling (10-15 seconds)
 * - HTTP-friendly TCP forwarding with proper connection lifecycle
