I don't know if this is an AT&T issue or what.
I've got a VPN set up using the Cisco VPN to connect with an iPhone 4S with iOS 5.
If I connect to the internet via a WiFi connection the VPN works fine. If I connect using the 3G connection from AT&T, VPN doesn't work. Any ideas? Is AT&T blocking or is there something else going on?
Thanks,
John S
