Traceroute can be a good hint, another way to confirm is on your router config interface, there should an IP address, subnet and gateway it connects to, with these values you could also verify it depending on what IP ranges it shows.
Comment on [Help request] How do I go about debugging my router?
Gonzako@lemmy.world 1 week agoOh! I am actually not behind Nat as I did a traceroute towards my public ip and it only did one hop. So it’s seems to be the port forwarding in itself not working

To add some more info to what the others are saying, if your public IP address is in the range
100.64.0.0/10(so between 100.64.0.0 and 100.127.255.255) then it is a CGNAT IP and you will not be able to make port forwarding/NAT work to/from the public internet because your public IP is not actually a publicly routable IP on the internet no matter what your ISP calls it. Hope that helps!
