I was able to play Internet radio directly on Squuezebox (Boom) or from Squeezecenter to Squeezebox, after upgrading to 2.27 can not do that any more, it says "Connecting" then "Connection Timed Out" on the squeezebox, it is the same on 2.28 & 2.29 releases.
I can play regular MP3 music on the squeezebox no problem only Internet radio???
someone did mention something about ipforwarding not working in a recent release and having to enable it manually.. that would certainly cause what you are seeing, but if you were experiencing that issue, you also wouldn't be able even to browse the Internet from your internal LAN, either. Have you tried that?
Colin,
Yes, I can browse the Internet from the internal network.
