Can't open port 80

hello, I've been looking to opening a site just for fun. The problem is, is when I open port 80 and set the right ipv4 it opens my routers gateway! Which is horrible, I don't want that. I also get a message when I open port 80, though I'm not really sure what it means...

I don't even want to use port 80, I want to use 443 for Let's Encrypt (https) though it seems like I need to have 80 open for Let's Encrypt to verify that I "own the site"

I can open port 8080 just fine though. But I don't want people to have to type:8080 at the end...

Does anyone know what's going on?

OS: Debian 10.2
