Centralization is bad for everyone everywhere.
That bring said… I just moved my homeserver to another city… and I plugged in the power, then I plugged in the ethernet, and that was the whole shebang.
Tunnels made it very easy. No port forwarding no dns configuration no firewall fiddling no nothing.
Why do they have to make it so so easy…
I have a similar setup and I just have the reverse proxy on the VPS. It then proxies back to the home server on whatever port the service is on. And yes you can forward the original client IP if you wish.
