So to start off I am trying to get all my internal websites working on a SSL cert. Thus meaning I need a domain to easily make this work, but what I am running into is loopback... at least I think that's the right term. So on the "internal" webhost machine is running apache2. It also runs docker that has been setup that I can get standard 192.168.1.* addresses for example. (not my actual subnet.) The webserver has 192.168.1.3 for example and the service I'm trying to reverse proxy is on 192.168.1.4 that is a docker container running on the same NIC. How do I get the two IP's to talk to each other? I would rather not have to keep typing the IP.
