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!

Buy a cheap VPS, setup a Wireguard or OpenVPN server (wg-easy is quite nice). Then something like Nginx Proxy Manager or plain nginx and expose your services over that.

Edit: if you need help, hit me up, love sharing my knowledge

I second this. I use a couple of dirt cheap VPSs from racknerd ($24/yr for 1 CPU/512Mb ram, but you can find coupons online to get them for $10/yr 1CPU/768mb ram) one does port forwarding over wireguard to my mail server so I can keep all my data in house, the other hosts an NGINX reverse proxy for all my web services. Works great. I use the reverse proxy for nextcloud and jellyfin for myself and 6 other users. Never had an issue. (Well, never had an issue I didn't cause myself at any rate.)

It's a little harder to set up than some of the other suggestions, but it's cheap, fully transparent to users, and doesn't expose your home network to the outside world.

As is tradition

Netcup is my favourite hoster in the EU, but I live in DE. 2€/m for 2c, 2/4gb ram, lots of traffic. They have coupons from time to time or xmas/easter/... deals. The whole front- and backend works like a charm too. Upload your own isos/qcow images, download backups, KVM is awesomely implemented too. Sadly they don't take crypto and you need a call verification or id via mail for your first purchase (understandable as a german hoster), besides that just wonderful :)

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 :)
