You add static routes to your private network on the PPTP server by using the route command at the command prompt. The static entries can be added by using a .bat file that contains the routes or by using the route command with the -p (persistent) option.
The route command causes all subnets and computers on the private network to be known to the PPTP server. Without the necessary route commands, the PPTP server would broadcast for every address required by PPTP clients.
To add the static routes to the PPTP server, run route with the -p option at the command prompt, as shown in the following example:
C:\>route -p 172.16.48.10The route command must identify all the computers or networks you want PPTP clients to reach.
