[Help request] How do I go about debugging my router? (lemmy.world)

Hi!

I am finally dabbling in some self-hosting and I'm having trouble on the very final steps.

The setup:

I have a simple NUC that's hosting caddy and a dynamic dns solution

I have port forwarded ports 443 and 80 to my local machine

I have a domain pointing towards my public ip

My router is a sercom 00200106 brought by my isp

The problem:

¿I can't seem to get past the router?

Whenever I try to get in through my local network I get an "intercept.hmtl" from the router and anyone to get from outside just gets a timeout.

If anyone has any idea how'd I go about moving forward the domains "https://gonzako.com/" I have managed to get caddy to show the "hello world" through localhost so I know the service is working

Many regards!

Gonzako

Edit: I am not behind NAT as I did a traceroute towards my public ip and it did only a single hop

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!
