Because you’re only ‘exposing’ the port on the peer to peer network.

You “publish” a port to holesail, then clients have to create a local proxy via holesail before they can access it.

I agree, It’s a dumb pointless claim. But I don’t think it’s misleading.

It looks like holesail is just tailscale, but on a much smaller scale. It’s not networks, it’s just ports.

I used to have Gentoo running a Libvirt hypervisor, which would then run multiple short lived isolated windows and Linux machines with GPU passthrough for all the different companies and projects I was working on.

Spent far too much time keeping the guest machine images up to date, and all the configs and stuff managed and synchronised.

Then my laptop died that I was using to manage everything so I gave up.
