Plex multiple network interfaces

Plex Media Server Desktops & Laptops

Hi all,
I have an issue with configuration of plex server.
I have 2 network card with this configuration

  • lan: ip 192.168.1.10 subnet 255.255.255.0 gateway 192.168.1.1 (router adsl connection nr.1)
  • wifi: ip 192.168.0.10 subnet 255.255.255.0 gateway 192.168.0.1 (router adsl connection nr2)
    From this computer I can reach all devices in this 2 network.
    When I open plex server sometimes use lan interfaces and sometimes wifi interfaces.
    There’s any way to allow Plex server to listen in all interfaces?
    Now I use 2 virtual machine whit plex server. the first have a bridge with lan interfaces and the second bridge with wifi interfaces. Media is in shared folder. Work, but I don’t like this setting, waste of memory and cpu performance.
    I’m sorry for my bad english. I hope you can understand me and help me with this problem.
    Thank you

Plex does not support multi-homing.
You can not expect it to work with more than 1 WAN connections.

Thanks for reply. I’m not interested for remote connection but only for use it on 2 lan

Even then it is not possible. Plex can only handle one local network - its own.
All others are treated as WAN.
You need to rethink your routing, I’m afraid.

Tip: if you build a custom routing from LAN1 to LAN2, you can declare LAN 2 as ‘local’ to Plex.
(Settings - Server - Network - ‘Show Advanced’ - “LAN Networks”)
However, some function still won’t work, like Plex Companion casting between the LANs.

I realise this is an old topic, but for completeness (and my interest) I believe this is now possible? You can tell Plex what your local network addresses are under settings, LAN Networks. Technically this is about bandwidth, nevertheless, if the routing is set up right, I don’t see why you’d need anything else. Probably also adding the list of IP addresses / subnets allowed without auth would be good too.

You would just need to forward port 32400 from both routers to Plex on their respective local IP addresses and ensure the operating system Plex is installed on knows how to get to both of those networks with it’s routing. I can’t think of any other reason why that wouldn’t work. It’s really a network routing question, rather than a Plex one.
