So I was looking into getting port forwarding set up and I realized just how closed-off the internet has gotten since the early days. It's concerning. It used to be you would buy your own router and connect it to the internet, and that router would control port-forwarding and what-have-you.

Now, your ISP provides your router, which runs their firmware, which (in my case) doesn't even have the option to enable port forwarding.

It gets worse - because ISPs are choosing NATs over IPv6, so even if you install a custom firmware on your router without it getting blacklisted by your ISP, you still can't expose your server to the internet because the NAT refuses to forward traffic your way. They even devise special NAT schemes like symmetric NAT to thwart hole punching.

Basically this all means that I have to purchase my web hosting separately. Or relay all the traffic through an unnecessary third party, introducing a point of failure.

It's frustrating.

I like to control my stuff. I don't like to depend on other people or be in a position where I have to trust someone not to fuck with my shit. Like, if the only thing outside my apartment that mattered to my website was a DNS record, I'd be really happy with that.

Edit: TIL ISPs in the US don't have NATs

Edit 2: OMG so much advice. My knowledge about computers is SO clearly outdated, I have a lot of things to read up on.

Edit 3: There's definitely a CGNAT involved since the WAN ip in the router config is not the same as the one I get when I use a website that echos my IP address. Far as I can tell ~~my devices don't get unique IPv6 addresses either~~. (funnily enough, if I check my IP address on my phone using roaming data, there's no IPv6 address at all). It's a router/modem combo, at least I think since there's only one device in my apartment (maybe there's a modem managing the whole complex or something?). And it doesn't have a bridge mode, except for OTT. Might try plugging my own router into it, but it feels like a waste of time and money from what I'm seeing. Probably best to just host services over a VPN or smth.

Edit 4: Devices do get unique IPv6 addresses, but it's moot since I can't do anything but ping them. I guess it wouldn't be port forwarding but something else that I would have to do that my router doesn't support

Here in Germany I get a "real" (non-shared) IPv4 address and a /48 IPv6 subnet I think. With Telekom at least. Vodafone is another story. I think the user must be able to use their own router because of some EU law.

Can't switch ISPs? I'd tell them exactly why I'm switching.

Did you contact your ISP about this? Most of them can adjust a setting for you to remove the NAT part, the feature is usually called dual-stack. If you are in the EU, you even have a fundamental right to use your own router, you just have to register your MAC with them.

Is your service fiber? Is your router a combined ONT and router? If its not and you have an ONT serving ethernet to the router, you can just plug your own router in.

You said it's through china mobile so is it a cell modem/router?

Just checked, it looks like it's fiber. Definitely has something plugged into the wall anyway - I'm kinda afraid of unplugging it and ruining my internet access.
