Exposing game servers over Tailscale

I'm quite happy to read that this approach performs well. I've experimented with tailscale funnel recently in front of FoundryVTT, and found it performed pretty badly — I assume due to the bandwidth limits. The main advantage was that it didn't require every player to have Tailscale installed/configured/running. It's certainly nice either way to be able to easily host something from a server with no accessible IP address.
