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.
in m limited sample size of one avm fritz.box, yes. What ivp6 address did you use to try and connect? a device typically has multiple - i.e. dont use fd00::, fe80::

Yeah I set it up to forward 80:80 and 443:443 but it didn’t seem to have any effect. Does port forward work on ipv6 the same way it does on ipv4?

I’d need to check it out, it’s been a while. But I tried pretty much all addresses that are printed out with “ip address” command on linux
