A C++ command-line tunnel that converts UDP traffic into encrypted FakeTCP, UDP, or ICMP traffic using raw sockets, helping bypass UDP firewalls and unstable UDP environments. It supports AES-128-CBC encryption, anti-replay protection, connection recovery, and pairs well with UDP-based VPNs like OpenVPN.
Use cases
- bypass UDP blocking or QOS by my ISP
- tunnel OpenVPN over TCP-looking traffic to avoid TCP-over-TCP
- disguise UDP traffic as ICMP to pass restrictive firewalls
- keep VPN connection alive when switching WiFi or replugging network cable
- encrypt and protect UDP traffic from replay attacks
- run a tunnel on an OpenWRT router or Raspberry Pi
When to choose
- you need to traverse firewalls or ISPs that block, throttle, or mishandle UDP
- you want to run OpenVPN or another UDP-based VPN without TCP-over-TCP performance issues
- you need a lightweight, dependency-free tunnel on Linux, Android, or OpenWRT with root access
When to avoid
- you cannot get root or cap_net_raw capability on the host
- your platform is Windows or macOS and you don't want to use the separate multiplatform fork
- you need a general-purpose VPN rather than a UDP traffic tunnel
