Not sure if this is a question for here or serverfault, but here goes.
I am having issues connecting to exchange via my CISCO VPN over 3G wireless; it simply won't connect. This works perfectly fine over a wired connection or via WiFi.
Summary:
Wired / WiFi -> VPN = Network access + Exchange connectivity
3G wireless -> VPN = Network access, No Exchange connectivity
Anyone have any ideas?
edit: I have seen this question asked a few times in a few different forums with no answers. (Except in experts-exchange, where I don't have an account).
