Quick question - if we were to change the external port from 32400 to say 4431, would this change be pushed to existing users that Plex is ‘shared’ with?
Do clients have the port hardcoded to 32400? Or is the traffic proxied through plex.tv?
Yes. That is what the input field for the remote port is for: https://support.plex.tv/articles/200289506-remote-access/
