It is a ASUS 500g Delux and i think it schould support multicast
mt-daapd is able to access the mp3 dir and it add the songs to the database. So far it works fine. The web-interface does not work. After logging in I only get error pages. I think this is a conflict with the native web interface of openWRT but I’m not sure about that. I can live without the web interface thats not the problem.
The bigger problem is that the server does not show up in iTunes. When the client comes up I can see the client packages with tcp-dump. But it looks like the server does not answer.
