Yeah the IP:s are there for the world to see, but you won’t easily know they belong to me unless I point to them from my domain.

I’m running a server at home without portforwarding. I connect to it using Nebula on VPS, which is like Tailscale without having to trust anyone.

I wouldn’t expose ports like that.

If security is a concern I would go with something like Nebula.
