We have two Windows Server 2008 R2 machines, one in our main office and one in a new office which we have just moved offsite. The main office has previously been handling client-to-server PPTP VPN connections.
Now that we have moved our second server out of office, we want to set up a demand-dial or persistent VPN connection from the second server to the primary. Using a custom setting RRAS profile, we have successfully managed to set up a site-to-site VPN connection so that from the second server itself, it can access any of the devices in the main office and communicate back. However, any connected machines in the second office cannot use this connection, even when using the second server as gateway.
The demand-dial interface is setup from the Second Server dialing into Main Server and a static route set up on RRAS for 192.168.0.0 with subnet mask 255.255.0.0 pointing down this network interface.
The main office has the network of 192.168.0.0/16 (subnet mask 255.255.0.0).
The second office has the network of 172.16.100.0/24 (subnet mask 255.255.255.0).
What steps do we need to take to ensure traffic from the second office PCs going towards 192.168.x.x addresses use the VPN route? Many Thanks in advance for any help the community can offer.
