Hi!
I often read suggestions to use something like Tailscale to create a tunnel between a home server and a VPS because it is allegedly safer than opening a port for WireGuard (WG) or Nginx on my router and connecting to my home network that way.
However, if my VPS is compromised, wouldn’t the attacker still be able to access my local network? How does using an extra layer (the VPS) make it safer?
How can you ever learn the risks of exposing ports if all answers are “if you don’t know you shouldn’t do it”?
The post explicitly recommends ONLY exposing the wireguard port, not 80/443/22 which one should usually not do anyways. Very different things!
Yes, and to be fair the OP doesn’t even need to expose a port on his home network. He can do the opposite and have the port exposed on the VPS and have the local router / server connect to the VPS endpoint instead. This will also remove the issues caused by having dynamic IPs at home as well.
