Status: Beta 🚧

An AI-driven VPN tunnel written in Rust with automatic path selection: IPv6 direct → STUN hole punching → relay fallback.

• Dual-Path P2P — IPv6 direct + STUN hole punching with auto-fallback to relay
• Smart Routing — automatic path selection, no manual configuration needed
• Multi-Tenant — cluster-based isolation for teams and environments
• Encryption — ChaCha20-Poly1305 (default), AES-256-GCM, XOR
• CIDR Mapping — resolve overlapping subnets (Linux only)
• Cross-Platform — Linux, macOS, Windows

curl -fsSL https://raw.githubusercontent.com/smartethnet/rustun/main/install.sh | sudo bash
sudo vim /etc/rustun/server.toml
sudo vim /etc/rustun/routes.json
sudo systemctl enable --now rustun-server

sudo ./client -s SERVER_IP:8080 -i client-identity

1. Login at rustun.beyondnetwork.cn and create a client identity
2. Download the binary from GitHub Releases
3. Connect:

   sudo ./client -s rustun.demo.beyondnetwork.cn:18080 -i <your-identity> -c xor:rustun@smartethnet.github.io
