Hello community,
i want to use a specify port like 8080. Because on Hotel rooms they are blocking the default plex port. And the moment i use the default port 32400 with a port forwarding. That´s work fine. But when i want to change the default port. Plex Media Server gives me an error message. I create a new port forwarding rule. But there´s is no success.
Did everyone have an idea?
There is no way to change the internal port. Your port forward should go from 8080 -> 32400.
The specify port you are changing tell the plex.tv server what port is open for it to talk to your server.
I think the 32400 belongs into the fields “Port an Gerät”
If this is indeed the input mask to define a ‘Port Forwarding’.
It is really weird they call it “Freigabe”.
So to be a little clearer you want to adjust your router in your home.
You set it up to forward external port 8080 to port 32400 on the IP of your Plex Server.
THEN IN PLEX SETTINGS
go to SETTINGS/SERVER/REMOTE ACCESS and on that page check/enable the setting “Manually specify public port”. In that field input 8080 and click the apply button.
Test from external web browser.
This sets up your router to forward any 8080 traffic to the port the plex server is looking for it. Also ironically on the plex server it will fill in port 8080 on URLs even though it doesn’t listen on that port for them. Essentially the router forwards the request.
Sounds goofy but works quite well.
Thank you for your help. This works now
