Required ports for iOS updating

We introduced iPhones to our company. The iPhones get iOS update notice.

It was successful to update when I used 3G connection. However, the update failes at verification step under our WLAN.

We have opened following ports to 17.0.0.0/8 already.


80, 443, 2195, 2196, 5223


I suspect that we need to open adittional ports.


Could you give any advice?


Thank you for your help in advance.

iPhone 5, iOS 6.0.2
