udptunnel is a small program which can tunnel UDP packets bi-directionally over a TCP connection. Its primary purpose (and original motivation) is to allow multi-media conferences to traverse a firewall which allows only outgoing TCP connections.
# udptunnel -s 443 127.0.0.1/51820
# udptunnel -c [SERVER PUBLIC IP]/443 127.0.0.1 50001
- Remember to open TCP port 443 on the server's firewall
- In the WireGuard client config file, replace the server's public IP (endpoint) with
127.0.0.1:50001
Sounds good.. would be nice to find a solution.
https://manpages.ubuntu.com/manpages/focal/man1/udptunnel.1.html shows that IPv6 is not supported, maybe due to this or even bigger problems..
