Watchguard XTM 5 + iTunes Store
Don't know if anyone else has experienced this, but we have a Watchguard Firewall in place and I'm having trouble getting the iTunes store to work through the staff HTTP(S) Proxy. Traffic monitor is showing nothing being blocked/stripped and I have exceptions in for *apple.com and *iTunes.com. There's no weblocker policy or application control policy in place to prevent this either. The store seems to load but I just get a blank white page, can login to iTunes fine but still the same. If I click on the tabs above (Music, Movie) the background colour changes like it should, but zero content. Can anyone offer any suggestions? It works fine when using our non-filtered HTTP(S) policy, but I'm reluctant to stick people on this outside of the server room.
Thanks in advance.
