I’m connected via a 4G modem. Got this setup about 3 years ago. In the beginning it was enough to look for the public IP (what’s my IP). The modem showed some sort of private ip in the ui. I’m running stuff at home (Homeassistant, Gitea,) and bought a domain and pointed it to my home IP via Cloudflare. After some time I’ve noticed my modem shows the public IP also internally. For about 2 years now it ran flawlessly, the IP changed from time to time, but not really more than once in several weeks.
For about a week all stopped working and the modem shows IP 100.xxxx and outside 85.something
I guess I’m behind NAT now.
Normal port forwarding on the modem is useless now.
Is it possible to open the ports via UPNP? I’ve tried via miniupnp from my Ubuntu server, but it just throws an error.
Personally I would strongly recommend learning how to do all of this. And then abandoning it for tailscale or something similar once you know what they’re doing behind the scenes. It’s incredibly useful knowledge but it’s also nice to have so much of the process automated and best practices like key rotation done for you. Plus unless your network is hugely crazy or enterprise, you can manage for the really great price of $0.
And if you really really want to self host (which I understand) there’s headscale for a lot of the features.

Thanks for the tip. Haven’t used tailscale (or sth similar) yet. But I’ll take a look into it :)
