Configuring connectivity Once you have determined which kind of connection you have, you can configure the appliance to connect to the Internet or intranet using the settings appropriate for that connection. DHCP Dynamic Host Configuration Protocol (DHCP) automates the network configuration of computers. It enables a network with many clients to extract configuration information from a single server (DHCP server). In the case of a dedicated Internet account, the users are the clients extracting information from the ISP's DHCP server, and IP addresses are only assigned to connected accounts. The account you have with your ISP may use DHCP to allocate IP addresses to you. Account types that frequently use DHCP are broadband cable and DSL. ISPs may authenticate broadband cable connections using the MAC address or physical address of your computer or gateway. See "Configuring connectivity" on page 30 for information on configuring DHCP to allocate IP addresses to your nodes. Before configuring DHCP for your WAN ports, you must select DHCP (Auto IP) as your connection type on the Main Setup window.
