title: Port Number for Incoming Apple Push Notifications
body: <p>What network services, port numbers, outgoing incoming or both, need to be open on a network for an ipod touch to receive Apple Push Notifications?</p>
  
  <p>I know the outgoing port number to set when sending the apns. The only thing is, in my school practically every outgoing (and incoming) port is blocked and as a result APNs do not work. I am sure that if I talked to my network administrator and told him which port to unblock, he would do so. So my question is: What network services, port numbers, outgoing incoming or both, need to be open on a network for an ipod touch to receive Apple Push Notifications?</p>
