Specifing a specific IP in Plex

Plex Media Server Remote Access
1

Server Version#:1.18.4.2171
Player Version#:4.12.3

Hi

I am having a small issue were if I have a power blackout, my Plex server reverts to an IP address that is an internal and not the external I want.

My plex is running on a Synology NAS and I am using to both network connections.
The 1st network connection (192.168.1…) is behind a Unifi Secure gateway and the other (192.168.0…) is plug directly into a Technicolor TG789vac V2 Modem.
I have tried port forwarding but cant seem to get it to work.
At the moment after a power loss I have to disconnect the NAS from the internal network for Plex to connect to the correct address.
Is there a way in plex to specify a specific IP address to allow it to be “Fully accessible outside your network”

It sounds like you have double NAT:

192.168.1.x -> 192.168.0.x -> modem.

If this is correct, only you can make PMS report correctly by making the port forwarding manually in the reverse direction:

modem -> 192.168.0.z Unify -> Synology on 192.168.1.x

In Settings - Server - Network - Show Advanced you can tell Plex.tv which IP / URL to publish but that is all.

Actually I think you have a routing problem because you have two default gateways with the same cost (directly connected).

I’ve never used this option, but maybe specifying the correct network interface name at Settings > Network > Preferred network interface can solve your problem.

The command ifconfig will give you a list of the available network intefaces

What’s the output of the command netstat -an | grep 32400 ?
