The Gallery server

[tonibm19]

The Gallery server may need to go offline for some time, starting probably on Dec 31st. There's no internet yet in my new house and I don't know if I can get a public IPv4 address once I do get internet there. I'll keep the server running in my old house for as long as possible, but on year's end the internet here will be turned off.

Any suggestions on what to do if I can't get a public IPv4? I was thinking of renting a really small VPS that comes with a public IPv4 address (AWS EC2 has a free trial for a year), and using SSH from the Gallery server to it, with reverse-port-forwarding. Not sure about the stability of this solution, though, and it would add a bit more lag to the game.

I don't really know if that can help but there's a tool called ngrok (https://ngrok.com/) that can "expose" your localhost without the need of port forwarding.
It's compatible with TCP so it should work for a minecraft server. See https://yiddish.ninja/sharing-your-local-minecraft-server-over-the-internet/
It has an ARM version so you could try to run it on the Pi.
