I am trying to set up a branch office, with a VPN connection via RRAS into our head office. The head office uses a 172.16.x.x range, while NIC of the branch office uses a 10.1.0.x. Both RRAS servers are running Windows 2003 Server, all updates applied. I have configured the head office as an RRAS server, and created a VPN PPTP dialup connection in the branch office. The VPN works OK, I can connect, and get 172.16.0.16 on the branch office VPN. I can ping & connect to any port accross the VPN. No problems creating a route to allow packets from 10.1.0.x to be send up the VPN pipe to the head office.
The problem I am having is configuring a route at the head office to route packets bound for 10.1.0.x down the VPN link to the remote office. RRAS will only let me add a route to either of the NICs. The "Route Add" command is much the same.
How do I add a route to the head office RRAS server routing 10.1.0.x packets out through the VPN tunnel?
Is there another way I should be doing this?
