wireguard-proxy

Proxy wireguard UDP packets over TCP/TLS

wireguard-proxyd is a server-side daemon to accept TCP connections from multiple clients and pipe data to and from the specified UDP port
wireguard-proxy is a client-side daemon that accepts UDP packets on a local port from a single client, connects to a single remote TCP port, and pipes data between them

Testing:

udp-test is a utility to send a UDP packet and then receive a UDP packet and ensure they are the same, this verifies packets sent through proxy/proxyd are unmolested
test.sh runs udp-test against itself and then through proxyd/proxy
udp-test -s runs udp-test against itself through proxyd/proxy by spawning actual binaries udp-test -is runs udp-test against itself through proxyd/proxy in same executable by using library, so does not test command line parsing etc

Testing with GNU netcat:

  • nc -vulp 51820 listen on udp like wireguard would
  • nc -u -p 51821 127.0.0.1 51820 connect directly to local udp wireguard port to send data to 51820 from port 51821
  • nc -vlp 5555 listen on tcp like wireguard-proxy would
  • nc 127.0.0.1 5555 connect directly to local tcp wireguard-proxy port to send/recieve data
  • so to test through wireguard-proxy run first and last command while it's running, type in both places
