I am trying to setup a wireguard VPN between two servers that are on tailscale. Server A is running Ubuntu with tailscale installed and server B is a Windows 10 system with tailscale installed. Server A and server B can ping each other over the tailscale IP (100.x.y.z). I have installed wireguard (PiVPN) on the ubuntu system and when when I connect using Windows 10 I can see data is sent but nothing comes back. Now I understand tailscale is already a VPN but I am trying to get to the internet through server A. Is this possible to do with tailscale and wireguard?
