Wireguard IS a VPN. He has somehow through his challenges of exposing services to the internet, exposed wireguard from his home to the internet for him to connect to. Then he can connect to his internal services from there.

It’s honestly the best option and how I operate as well. I only have a handful of items exposed and even those flow through a DMZ proxy before hitting their destination servers.

What instance did you go to then? I don’t keep up on “the best” instances, or those that defederate or block certain things. I was part of kbin.social at first, then moved to .world.
