    Enabling the DHCP Server The Multi-Tech DHCP (Dynamic Host Configuration Protocol) server feature manages all IP address assignments within a local/private LAN. The DHCP Server maintains a list of available IP addresses and when a client computer asks for one, the DHCP Server sends the IP Address to the client. The client computer, configured with that information, can then participate in the TCP/IP network.

    The virtual server feature of the ProxyServer allows you to have multiple servers on your local area network (LAN) with one static IP address (from your ISP or Multi-Tech’s Global Dynamic WAN Addressing) assigned to each WAN port. A normal internet connection requires a static IP address for each server on your LAN.

    First, choose a domain name for your company. A domain name is the unique Internet name, usually the name of your business, that identifies your company. For example, Multi-Tech’s domain name is multitech.com (where .com indicates this is a commercial organization; .edu denotes educational organizations, .gov denotes government organizations).
