NAT traversal built with Rust and Tokio
A lightweight, high-performance, and secure intranet penetration tool with a binary size of around 5MB.
Features
- High performance: high performance, packet-loss resilient, high throughput, no GC pauses, and low memory usage
- Tunnel protocols: TCP, UDP, HTTP, HTTPS,SOCKS5 and more
- Transport protocols: TCP, KCP, WebSocket, QUIC, with TCP multiplexing support
- Security: Token-based tunnel authentication, TLS and mTLS encryption; HTTPS supports transparent forwarding and client-side TLS termination
- Cross-platform: Windows, Linux, macOS, FreeBSD, and more
- Operations: lightweight Web admin UI and cross-platform desktop client for easy configuration and monitoring
