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

Traceroute can be a good hint but try to do one to an IP like 1.1.1.1 and see the initial jumps, another way to confirm is on your router config interface, there should be an IP address it has assigned, subnet and gateway it connects to, with these values you could also verify it depending on what IP ranges it shows, and see if the assigned IP or Router's WAN IP is the same as shown when you search for "what is my IP" online.

If you can confirm that your router assigned WAN IP is the same as your public IP, then it could be a misconfiguration of the port forwarding on the router or a firewall block either on the router or the computer
