If a network or host route is needed to enable communications between the user’s workstation and the OnBoard, the user must manually add the route on the user’s workstation before creating the PPTP VPN tunnel.In addition, the user must manually create a static route after the PPTP connection is established to inform the workstation that the device to be contacted is at the other end of the point-to-point link. The route must include the PPTP address assigned to the OnBoard, which the user can discover by running the ifconfig or ipconfig command.The following screen example shows the PPTP interface IP address output from the ipconfig command on an Windows NT operating system when PPTP has assigned an IP address of 192.168.2.1.If the user needs to communicate with devices on two separate private subnets, the user must create a route to each private subnet or to each device.For example, to communicate with all devices on a private subnet whose IP address is 192.168.4.0, when the network mask is 255.255.255.0, and the PPTP-assigned OnBoard IP address is 192.168.2.1, the following route would be needed:If additional devices must be accessed on additional private subnets, additional routes must be created to each of the subnets.To communicate with three devices on a virtual network whose IP address is 172.20.0.0, whose network mask is 255.255.0.0 via the OnBoard, and PPTP has assigned the OnBoard the IP address 192.168.2.1, the user would need to configure a route like the one shown in the following screen example:If a virtual network is configured, the user needs to only add a single network route to the virtual network. Check with the OnBoard administrator for which routes you need to configure to connect to the devices for which you are authorized.Creating a default route on the user’s workstation to the OnBoard would work, but it would result in loss of DNS and other local services (such as Internet and mail service) for the user’s workstation.
