FIX: You Cannot Use Virtual Private Network (VPN) or Point-to-Point Tunneling Protocol (PPTP) Over Certain Networks (822160)


The information in this article applies to:

  • Microsoft Windows CE .NET 4.1

SYMPTOMS

After you establish a virtual private network (VPN) or Point-to-Point Tunneling Protocol (PPTP) (VPN/PPTP) connection to a network whose subnet includes the subnet of the base network, the client cannot communicate.

For example, if the base subnet is 10.20.x.x and the VPN/PPTP subnet is 10.x.x.x, you cannot reach any network destinations.

CAUSE

The client is incorrectly using a subnet mask that is provided by the VPN network (for example, 255.0.0.0). The client has to use a subnet mask of 255.255.255.255.
