I'm still having trouble with an exercise I'm trying to do to learn how to configure RRAS on Windows Server 2012.

The server in question has a single NIC. The local LAN is 192.168.1.X   If I use a static IP scope within that range or DHCP, the VPN works fine so long as the opposing network is not the same scope. The problem with this is that 192.168.1.X is VERY common ;)

I've been trying to create a different subnet for use with the VPN and have that scope translate over to the real internal LAN, but to no avail. For example, if I give the VPN a scope of 10.0.76.50-150, I can connect. I can also see the VPN server by it's internal IP address, but I CANNOT see anything else on the network.

Help?

   That is correct. It will not see them because they are in a different IP subnet.

  If you use the same IP subnet for the LAN and the remotes, the server looks after things and it just works. This is called on-subnet addressing. If the remotes and the LAN are in different IP subnets, you have to set up routing between the two subnets. This is called off-subnet addressing. This matter is well documented. you can start with this TechNet article.
