Thanks. Xfinity (my ISP) supports only TCP and UDP for Xfi Gateway and not HTTP/HTTPS.

The thing which I don't know is how to remove Xfi Gateway and use my own gateway/router.

HTTP and HTTPS are layer 7 protocols that both go inside the layer 4 protocol TCP.

So port forward TCP and you'll be good.

Perfect. Thanks. That was my doubt. Will try it out.

Yeah, most routers have a predefined list of "Applications" but you can add a custom application with custom port.

Back in the day, DynDNS actually allowed the IP to DNS as a free service.

Oh, I forgot to mention HTTP uses TCP port 80, and HTTPS uses TCP port 443.
