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!
You say that as if most don’t hold a monopoly in their available regions. At least in America, you typically have the choice of one, maybe more if you’re in a largeish city, and I suppose you have the option of a 5G hub but that’s terrible for running services.
Ouch, I was not aware of that. Here in scandinavialand we have a few local or regional ones in each area, plus a few big ones that cover the entire country.
Once the fiber is in the ground, “any” ISP can use them, regardless who buried it. I think it’s a remnant from 20ish years ago when the default was ADSL over copper, and the telecom cables were considered public infrastructure.
Dude I’d kill for that availability. Here, the companies own the infrastructure, and can offer to let others use it if they’d like but that doesn’t usually happen.
Yeah, the US is very limited in ISP options. In my area there is one massive provider, and two or three small providers. The massive provider does up to 1Gb but it’s cable and speeds fluctuate. The other providers can manage 250Mb and that’s it. Also, upload on ALL plans available in my area caps out at 20Mb/s. It’s a joke and the city won’t let any fiber companies in because of an exclusivity contract with the big cable provider. It’s baaaaaad
I’ve had plenty of rants about Norwegian broadband (or lack thereof) over the past 25 years. It’s a bit of a long story, but the gist of it is that during the 90’s there was this one company (Telenor) which had practical monopoly on telecom (it was the private remnant of what used to be part of the government), and of course they didn’t want to develop broadband 8nfrastructure as the made shitloads of money by selling ISDN at the time. Broadband was available in the biggest cities only, and even there it was limited. And the punchline of that joke was that when I was on dialup I had to pay by the minute. During that time, hearing about not having to pay by the minute in the US sounded like paradise to me.
But luckily competition happened, and Telenor realized they had to allow modernization or be left out of the market entirely. Small communities could sign up to have broadband “delivered”, and once enough people had signed up for an ISP to considet it profitable, digging would start. Today, twenty years later, I’m pretty satisfied with how it turned out. I live practically in the middle of nowhere, in a tiny industrial town sqeezed to fit into the terrain, where three of the cardinal directions are blocked by mountains and the fourth being a fjord. And I have 1gbit both up and down.
