Hello all. I'm bouncing around ideas in my head right now, and I want to take the next step in my home infrastructure. As it stands, I have my main docker server that hosts a variety of stacks and containers, and of course my nginx proxy manager as well.

Basically all the containers have the ports open that they need, and the proxy is just hairpinning back into the same VM. So DNS for my friendly name stuff points 10.178.200.4, and then the proxy points to 10.178.200.4:8787 or 8989 or whatever for the individual apps.

I feel like, at least in my mind with the docker virtual networks, that I should be able to close all the ports except 80 and 443, and route traffic to the virtual IPs that come from docker, and the networking can be done internally. Is my brain working, or is this stupid?
