Peter VágnerI'd like to create #wireguard tunnel between two natted machines. I'm fine with using an intermediate third machine for IP addresses and ports discovery.
The idea outlined in this article sounds verry appealing to me.
However I'm wondering is there something that is developed further beyond a proof of concept I might look at instead? I know there is #tailscale. That sounds too much for me unfortunatelly as I do need to register with them and similar. Thus I'm exploring if there is something I can self host.
WireGuard Endpoint Discovery and NAT Traversal using DNS-SD
In this post we will set out to establish a WireGuard tunnel between dynamically addressed peers that are both sitting behind a NAT. One of the primary goals for achieving this is to stick with WireGuard in its purest form, the code that now ships with the Linux Kernel.
