The second step in setting up a Vista VPN is to configure the server to act as a Dynamic Host Configuration Protocol (DHCP) server. This enables the server to assign IP addresses to VPN clients when they connect to the network. During the configuration process, you will have to create a DHCP scope. The IP addresses within the scope must not be in use anywhere on your customer's network and must fall into the same address range that is currently used.
