No amount of claude can handle the key thing that Tailscale fixes about wireguard, all of the connection to connection logic is handled be it direct, via all sorts of weird hole punching or via relays. Wireguard itself is horrible to do this with, half the time you're just looking at `wg status` wondering why the packet counter isn't incrementing today. It can never achieve the magic that is a direct connection between plane wifi and a host that's behind NAT on the ground.
Functionally they are. Allow traffic aiming at this address and this port to arrive on this server.
Not that my WireGuard connection needs nat as it terminates on my router. And I use private ip ranges as I want to be sure that if WireGuard drops out for some reason traffic doesn’t route over the unencrypted path. Defence in depth.
