Question: How can I configure Plex Media Server (PMS) to listen on a specific interface?
Scenario: My Synology DS214+ (running DSM 6.0.2-8451 Update 1) is connected via CAT 5 directly into my PC. The DS214+ also has a USB wireless adaptor that's connected to my home network and my intention is to use the iOS Plex app to connect in remotely to the wireless interface (as the physical isn't connected to the router since its in another room).
Problem: When I install PMS (1.1.4.2757-24ffd60) it discovers my public IP okay but in the Server > Remote Access tab within PMS it has the "wrong" mapping. It maps to the physical interface rather than the wireless adaptor, hence I get a red cross since I can't have the router port-forward as it isn't physically connected to the NAS:
Please see relevant PMS log below:

If anybody can point me in the right direction please it would be greatly appreciated as I really want to get this working on wireless.
