Yeah, thanks to u/postnataldrip@lemmy.world I contacted my ISP and found out that in fact they were blocking my port forwarding capabilities. I gave them a call and I had to pay for a public IP address plan and now it’s just a matter of testing again.
Thank you very much to everyone involved. I love you.
It was Megacable by the way. If anyone from my country ever encounters the same problem I hope this post is useful to you.
Here’s the original post:
Hey!
Ok, so I’m trying to figure this internet thing out. I may be stupid, but I want to learn.
So, what I’m essentially doing is trying to host my own raw html website on my own hardware and get it out to the internet for everyone to see (temporarily of course, I don’t want to get in trouble with hackers and bots) I just want to cross that out of my bucket list.
What I’ve done so far:
I set up a qemu/kvm virtual machine with debian as my server
I configured a bridge so that it’s available to my local network
I got my raw html document
I’m serving it locally with nginx
I tried to set up port forwarding (I get stuck here)
Right now everyone in my home can see my ugly website if they go to 192.168.1.114:8080 (since I’m serving it through port 8080).
However, I want to be able to go outside (I’m testing it with my mobile network using mobile data) to see my website.
I’ve configured port forwarding on my ZTE router (ISP-issued) with the following parameters:
But now, if I search for my public IP address on my phone I don’t get anything. Even if I go to
my.public.ip.address:8080
(did you think I was gon-give you my public ip?)
I don’t get anything. I’ve tried ping and curl.
ping doesn´t even transmit the packages, curl says “Could not connect to server”.
So, If you guys would be so kind as to point me in the right direction, I pose the following questions :
How do I even diagnose this?
What am I missing?
Am I being too stupid?
What do I do now?
(Here’s a preview of my ugly website)
I also own a domain (with cloudflare) so, next step is getting that set-up with a DNS or something.
Your ISP might make you go through another layer of NAT. Can you find the WAN IP address of your router and compare it to your public IP address from a website such as ipinfo.io ?
If they do not match, you’re probably out of luck and will need to forward your port from an actually public IP in order to achieve what you want
More details : CGNAT (Carrier Grade Network Address Translation) is basically a second router between your router and the public internet. This second router is configured in the same way as your personal one, the main difference being that your ISP fully manages it. From the viewpoint of this second router, your WAN IP is a private IP, and you share one actual public IP with several other customers (the same way all devices on you LAN share one single WAN IP)
Performing port forwarding from the public internet to your LAN, when behind a CGNAT, would require you to be able to configure a forwarding rule in the ISP’s NAT, which you usually cannot do.

Yess!!! Thank you so much! I gave them a call and got the “public ip service” for some extra 5 dollars (in my country’s currency)
Glad I could help :)
