[IDEA] BBC Sounds via upmpdcli?

The script should select the correct interface automatically. Do you use both wired and wifi?
Anyway you can specify the network adapter using the variable UPNPIFACE.
Let me know if this helps.

It's working on my test pi4, which is only used on the wireless network.

I was using docker rootless, which has a different network configuration for some reason. 
Removed the rootless part and all's working now.

Many Thanks GioF_71

Moving on to the 'production' pi5 which uses both wired and wireless networks, the UPnP media server only appears on the wired network.

Almost there!

Where do you want the media server to appear?
An instance can only appear on one network, but nothing stops you from instancing two containers, each on a different network interface using the variable I mentioned earlier.
You might need to use different port offsets (not sure considering you would be using two networks).
Let me know if this helps.
