Question : Vpn assign address, Windows

I have a 2003 r2
I have enabled the VPN Service, from the server manager wizard.
and the service is working.

I can VPN in and access the server.
But I want to have the VPN hand me one of 8 address and gateways
right now it iis handing me a 168.xxx.xxx.xxx address

I want it to had me a 192.168.1.12-192.168.11.20 address with the gateway
begin 192.168.1.1

I tried emableing the this from the wizard but I was then disconneced from the server.

How do I setup so the VPN user get this address range and this gateway.

Answer : Vpn assign address, Windows

Just to clarify...did you really want to say 192.168.1.12-192.168.11.20   or did you mean 192.168.1.12-192.168.1.20

You should be able to go to Adminstrative Tools, Routing and Remote Access,  

In the left window right click on the Server Name > Properties > Click on the IP tab

Change from Dynamic to Static and enter in the address range you want to use.
