IP routing RRAS style
Below is a Technet blog entry I found quite helpfull First the basics on IP address/routing on RRAS perspective: Broadly there are two set of machines (or subnets) which needs IP address - one is the LAN machines (which may be obtaining IP address through DHCP Server) and other is the remote access client or VPN client machines (which gets IP address through RRAS server - via IPCP). For the second case, the RRAS server may be configured with a static address pool OR may be obtaining the IP addresses from a DHCP server (on behalf of VPN client). RRAS server creates a virtual interface (called as Internal interface or RAS Dial-in adapter) which is also assigned one IP address. This IP address is taken from the pool configured for VPN clients. The IP address pool (or subnet) can be shared between LAN machines as well as VPN clients OR can have different pool. For example, all LAN + VPN clients can have a shared pool as 192.168.1.1 to 192.168.1.254 OR LAN machines may have pool as 192.168....
