Hello again,
To clarify, specifically I am trying to use my Plex docker image outside of my network. Because Plex uses port 32400 to access any given Plex server from outside, I;ve forwarded the ports via Sophos. However, upon testing open ports on my plex server from outside my network ... (by simply using the native Plex "server --> Remote Access --> retry" button). I receieve the response "Not available outside your network" when it totally should be becuase all the necessary ports are forwarded!
Likewise... when i try to forward torrent traffic on a specific port in Transmission, Transmission consistently reports that the designated port is Closed.
So... thanks for your input. I'm just going to keep plugging away until I get something sorted.
Port forwarding in your firewall doesn't have anything to do with your internal network.
So for docker containers to speak to each other you have to use the ports you configured the containers to use.
If you want one container to speak to another you use the IP of unraid and the port of the container you want to connect to.
I haven't set up any apps to talk to plex, so don't know how to do it. I didn't think any one could talk to plex, but plex only looks for changes in your library and then adds the new content.
So what are you trying to do? You said that transmission and other containers couldn't talk to plex, but now you say they can talk to each other?
Are you trying to get the containers to talk to a plex server outside your network?
Or simply trying to access your containers from outside your network?
