Here is my issue, I currently have a 2504 with 3 access points. Now, I enabled multicast on it so that Apple TV and Airplay work fine, my printer communicates via Bonjour, so it that respect everything seems good. I can Airplay all day long to my hearts content. First, I couldn't use the Remote app to control Apple Tv or iTunes on the computer. I found the bug report about mDNS snooping causing this to fail. So I turned it off, now the Remote app controls my iTunes app on my computer, but the Apple TV still doesn't see the iPhone as a pair-able device. Has anyone experienced this? I am running 126.96.36.199 on the 2504. The appletv and iphones are latest os'es.
