Dear all, I have a wireless network connecting through TMG to a DSL line, all wireless clients are working properly, the problem is with the iPad and iPhone users, the https traffic is being blocked, and a nagging authentication window keeps appearing to the users. The rule at the ISA that passes the traffic is set to allow all traffic, and the OS at the iPhone/iPad is 5.0.1, The problem specifically appears when gmail is configured on the iphone a window keeps popping up for https authentication, Any help is greatly appreciated, Thanks, Ruba
