Using Apple TV to connect your iPad to your Whiteboard or HD TV

Using Apple TV to connect your iPad to your Whiteboard or HD TV

Many teachers have been reporting to me that they are having issues with their Apple TV’s.

Usually the cause of this is that they are getting the devices delivered to their School and trying to set it up in their classrooms.

By default most U.K Schools have a p r o x y server filtering their Internet connection. Nine times out of Ten the Apple T.V cant bypass the P r o x y Server unless your technician has opened specific ports.

The trick to getting a perfect setup is to take the units home and set them up there.  Or alternatively, if your School has a direct internet connection that has no p r o x y server attached set it up using that connection.   Once ATV has been set up it will work fine on the connection with a p r o x y.  *NB Keep your ATV remotes nearby though just in case you need to reset the time/date.

Some colleagues of mine were discussing this problem recently. Neil Emery Suggested:

Either separate network or add the MAC address of the AppleTV to the P r o x y bypass meaning that it doesn’t need to go through the p r o x y server.

Separate network makes it harder as the neat sharing stuff (AirPlay) will only work with devices on the same network, unless they have a knowledgable network manager who understands how to configure WAN based Bonjour. 

A quick solution is to have a Mac connected to the internet via Ethernet then to use Internet Sharing to create a wifi network for the AppleTV to connect to. That way the mac is working with the P r o x y server and the AppleTV thinks it has a direct connection.

In addition to this Paul Parry added to the conversation

  • These network ports are used by Apple TV for communications on your network.
  •  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.
  • Some of these ports may already be open but their own network team will be able to arrange for the other ports to be opened up.

Thanks to Vanja Milovanovic who brought this issue back to my attention, and Neil Emmery and Paul Parry who helped provide the more detailed solutions.
