I´ve got the same problem.
I can access to endian management but I can´t connect to a server on the LAN using terminal server. When I do an ipconfig it not appears default Gateway.
My Endian is 2.5.1
I always have problem with these 2 situations, so you check that:
1. your lan and remote lan are different
2. you launch vpn as administrator (in log you can see error adding route)
