STUN isn't something that runs on your router. You can disable UPnP in your router and still use Tailscale perfectly fine. https://tailscale.com/blog/how-nat-t

- aborsy 5y agoI thought STUN uses UDP packets, as the name suggests (Simple Traversal of User Datagram Protocol (UDP) through Network Address Translators), as well as standardized port numbers. I thought you could filter its traffic based on protocol and port number. Enterprise routers sometimes allow only 80/tcp and 443/tcp egress traffic. That’s why sometimes Tailscale falls back to relaying, which is pretty slow (unless in the future they deploy large number of relay servers around the world).
