SonicWall Blocking Access To AppStore
We are using a SonicWall firewall at work and no user cannot access the AppStore using iOS 6 or AppleTV. iOS 7 devices seem to work fine. The only common denominator is the SonicWall. I could not even activate a newly purchased AppleTV within the network, had to connect to my mobile hotspot to activate.
I have whitelisted all 4 of Apple's servers within the firewall and the 2 ports were already opened from other internal applications. What am I missing that needs to be done to allow access for activations and the downloading and using of apps?
iPhone 4S, iOS 6.1.3
