Some version of iTunes (or Mac OS X?) introduced that bug. AFAIK it has been fixed. I certainly haven't seen it happen in ages (iTunes 8.2.1 under 10.5.8), but it is possible that I only achieved that by tinkering with "something"... Shouldn't be too hard to find discussion of that bug through a search engine. And it shouldn't be too hard to ensure that your OS and iTunes versions are up to date ;) > So I click in that window in the "Open Firewall Settings". But I don't > know what to alter there. Nor does anyone else, if you don't say what your settings are :) Still, my bet is on that bug, not your firewall settings (if the firewall would be blocking AirTunes, it would be doing that all the time, not now and then). -- Sander Tekelenburg, <http://www.euronet.nl/~tekelenb/> Mac user: "Macs only have 40 viruses, tops!"

Thanks, Sander. I found this page: http://discussions.apple.com/thread.jspa?threadID=1788066 with this hint: "Aha. Just solved my own problem. Turned out the problem was my main wireless router (Netgear), which creates the wireless network that the Airport Express then joins. The netgear's firewall was blocking ports 5000 & 6000. I created a custom service (under Port Forwarding/Port Triggering, then Add Custom Service) which I gave ports 5000-6000, UDP mode, and pointed it at the Airport Express's IP address." On my Imac I looked up "Port Forwarding" and "Port Forwarding" with the computer's Help search engine but there's nothing. So I don't know how to do this.

Forget that. I see no reason to expect your problem to have anything to do with port forwarding at all. You haven't told us how you have configured your Airport Express. Is it only doing AirTunes? Or are you also letting it be a wireless access point, router, dhcp server, or whatever? > My Sharing control panel > Internet settings say "Share your connection > from > Built-in Ethernet" and "To computers using > Airport."

IIRC, you need to make sure that "Block UDP Traffic" and "Stealth mode" or not checked. (Only relevant if your Firewall is on. But you shouldn't have it off anyway, so...) -- Sander Tekelenburg, <http://www.euronet.nl/~tekelenb/> Mac user: "Macs only have 40 viruses, tops!" PC user: "SEE!

How can I determine that? Thanks. Every day I have to fiddle around with the settings to get the music to emanate again from the Express box and I have to keep walking between the two rooms to hear if the music working on the Express box, and usually it's not. Usually the music comes from the computer, but not the Express. >> My Sharing control panel > Internet settings say "Share your connection >> from > Built-in Ethernet" and "To computers using > Airport."
