I have 2 servers, 1 stays on all the time the other i need to disable from time to time to render video or game.
The issue i have is that i can only make 1 of the servers accessible to the outside world at a time as currently the only allowed port for Plex is 32400 and i can’t forward this port to more than 1 device.
My request is to allow more than 1 port for Plex, this would allow me to run 2 servers at the same time.
There is a difference between the internal LAN port and external WAN PORT.
The internal LAN Port can not be changed (32400).
But the External WAN PORT can.
So you have two PMS on two separate LAN IPs both using PORT 32400 which is fine (192.168.1.1:32400 & 192.168.1.2:32400 for example). You then need to assign two different external PORTS for these in your router
In order to forward a port for Plex Media Server, you’ll need three main pieces of information:
WAN/External Port: Port 32400 (TCP) is default, but you can generally use any available port in the 20,000 to 50,000 range.
LAN/Internal Port: This will always be 32400.
IP Address: The local IP Address of the computer running the Plex Media Server. This is what you did above. Important: While you can choose any valid WAN/external port number you desire, the mapping for the LAN/internal port must always be 32400 (TCP).
