@Arnie97 this helped me out two years later. Thank you very much!

For anyone (or me) looking at this in the future: Compile the patched version on both sides. Keep the AllowedPorts string on the config, it doesn't matter what port to specify.

Why need this? We need access to all the ports if we're routing internet via the tunnel.

I recommend checking out https://tailscale.com/. It's free for personal users and does what this project does, but much better and with far more features.

[arinc9]

Does tailscale use wg(8) to configure the tunnel interfaces? I want to run it on a network where the UDP packets including the WireGuard header, which the header is constructed by wg(8), are blocked.

This is why I currently use your project here.

heh this seems to break for me slightly - connections just drop every n minutes or so. Doesn't happen if I just specify a big array of ports allowed (but that's not practical and sometimes a "bad one" gets hit)

hmmmmm
