NAT busting is a minus. If apps can create holes in your network and “bust your NAT,” your network is not well secured; you should disable UPnP and filter egress. Also, you gain simplicity but give up to coordination servers, that can be a privacy and security problem.

Tailscale isn't using UPnP. See https://tailscale.com/blog/how-nat-traversal-works/ https://tailscale.com/blog/how-nat-traversal-works/

  That was an interesting read. Turns out they do use UPnP, but it's just one of many tools they turn to when other techniques fail.
