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.

upnpc -a ifconfig enp1s0| grep "inet addr" | cut -d : -f 2 | cut -d " " -f 1 22 22 TCP

Can I use this to somehow open the ports via UPNP on my modem and bypass the blocking? I can’t even OpenVPN to my modem anymore.

EDIT: i also run AdguardHome, that I use as Private DNS on my Android phone

UPDATE: everything except Adguard Home used as Private DND on my Android works! I’ve used this: https://github.com/mochman/Bypass_CGNAT/wiki/Oracle-Cloud-(Automatic-Installer-Script) - free Oracle VPS + automated well described script. Even HTTPS works fine!

    So I am wrong for saying water is water and not fire?

      Except you keep claiming it’s fire. It’s not fire, so stop calling it such.

        You are extremly confused, sorry to say. Please look up the difference between “Internet” and “Intranet”.

          No, I don’t think I am. You’re just wrong and don’t want to admit it. Some self reflection will do you good.

            There is nothing to admit. You are simply not willing to concede that the original definition of “internet” is still valid and watering that down serves no purpose other that muddling the waters and allowing huge corporations to increase their profits by cheating on their customers.

              See above comment for reply then sprinkle a bit of irony for the projection coming from you.

                Well, if you insist on stanning for multi billion dollar companies that are cheating on their customers then I guess all we can do is to disagree.

                  No, just disagreeing the bullshit of a clueless internet stranger.
