I am a newbie trying to connect my HTC HD2 smartphone running Windows Mobile 6.5 to my office VPN. I have set up the VPN dialer ok using PPTP and the router is a Vigor2600 plus series annex A. I can connect to my office VPN ok using a Windows XP based machine but the phone just wont go in. The phone is connected to my home network wirelessly. Are there some other settings I need to enter into the router to enable a smartphone to connect?
