Ok, I’ll share the ultimate guerilla-selfhosting challenge I can’t figure out yet: what if my internet connection is G5 prepaid sim card in the middle of the woods (it actually is)? Apparently, I do have IPv6 more or less stable (undocumented), but that’s kind of limiting at times. Seems barely possible, but!
The https://homebrewserver.club/low-tech-website-howto.html#network states:
The fiber connection itself is not necessary, especially if you keep your data footprint small, but a fixed IP adress is very handy.
which kind of implies someone figured out a way to get around it. Would someone share the trick?
Assuming reliability is the priority I would suggest going with Tailscale Funnels or a cheap VPS acting as intermediary.
I don’t have a lot of experience with dealing with GCNAT, but perhaps you could look into some solution with UPnP or RFC 6887.
