I have my Windows Mobile 6.1 Device connecting to my home router via PPTP VPN. I am able to RDP into a machine at home and see the screen. This will last for no more than a minute. The VPN connection will drop for no apparent reason.
Connecting to the RDP session via wifi @home works fine and never disconnects. Connecting via VPN and RDP from a regular windows machine is fine. It is something Windows Mobile and VPN related.
How can I keep my VPN connection alive when using Windows Mobile?
