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
According to this article, it looks like port 8088 is also used along side port 80 for software updates.
Hello Zane W,
Thank you very much for the comment! I will check the port.
