I'm gonna be a noob for life but managed to get connection to office Exchange server via VPN on cellular connection but when I got home and tried to connect via wifi (I live out of 3G area) I get a long wait and "Could not negotiate connection w remote PPP server" - which I thought looked like some kind of time out cos it might still be connecting via GPRS. And can't see anywhere in VPN settings to use wifi connection.
But apple support says "VPN works over both Wi-Fi and cellular data network connections" (http://support.apple.com/kb/HT1424)
So, anyone know do I use VPN over wifi?
NB: Saw this which looked ominous... http://saunderslog.com/2008/08/06/configuring-iphone-for-vpn/
It reads: "Now for the bad news. Having done this [[getting VPN to work over cellular]] , you may find (as I have) that you’re no longer able to set up a VPN connection over WiFi."
