Asked by dance1bb in iPhone, Proxy/Firewall Anti-Virus
Basically All Active Sync Testers Internal and external of our network work indicating everything is working as intended. Firewall ports 443 are open on our GTA GB-OS firewall. We are using Intrusion Prevention. For whatever reason the iphone has intermittent access to activesync whether you connect to the wifi on the internal network or utilize the 3G network. It will connect connect to the server, download messages on an intermittent basis. It will have an excessive amount traffic passing. If you utilize the activesync tester on the iphone the test will indiciate failed to connect to the sever, timeout. Basically what I think is happening is for whatever reason the iphone is taking an excessive amount of time to interact via ActiveSync, it takes so much time that the tester will fail, however the iphone must try much longer and is eventually successfully synching via activesync but takes a very long time and passes an excessive amount of data draining the battery quite quickly. These are my initial observations.
