Subsonic Assigned IP Address

[mcleanap]

So I have Subsonic running on an unRAID server. I have had this running for a few years now. I just upgraded my unRAID server, and thus installed the latest version of Subsonic.

Things are running OK, but something odd is happening. My internal IP address for Subsonic is 192.168.1.200:4040

First, when I went to connect to Sonos, I get the following log entry:

Enabling Sonos music service, using Sonos controller IP 192.168.1.110, SID 242, and Subsonic URL http://192.168.122.1:4040/ws/Sonos

Note that the IP address that Subsonic is trying to register with Sonos is 192.168.122.1:4040. I would expect this to be the same as the IP address I am using for accessing Subsonic GUI. 192.168.122.1 is not even in my IP range on the router.

In addition, I have this setup to access externally using the custom URL. It works fine when I am not connected to my own network. When I am though, it fails to resolve and it ends up trying to resolve to http://192.168.122.1:4040

Any ideas what is happening here?
