Network ports to open to allow Airplay to work correctly?

I'm trying to get Apple TV working on a WiFi network that is heavily locked down. Which ports do i need to open for Airplay/Bonjour to speak to my iPad and Apple TV? I've unblocked the following list

TCP port 123 is used to communicate with a network time server.

TCP port 3689 is used to communicate with iTunes while using the iTunes Library Sharing feature.

UDP port 5353 is used by Apple TV for automatically finding computers with iTunes on your network using Bonjour.

TCP port 80 is used for communicating with podcast servers.

TCP port 80 and 443 are used for basic and secure communications with the iTunes Store via the Internet.

TCP port 53 is used for regular DNS.

Thanks,

Jason
