Hi,
If you are connected, that basically means the authentication part is good and you are having issues routing the encrypted traffic across the VPN Tunnel.
Where are you connecting the VPN Client from. Is the VPN client behind a PAT device.
Once you are connected, Try pinging a valid ip address on the remote side and right click on the VPN Icon and look up the connection status. Do you see packets encrypted ?
And also, do you know what kind of VPN Server you are terminating the VPN Tunnel.
I hope it helps.
Regards,
Arul
