RangeMax Wireless-N DSL Gigabit Modem Router DGN3500 User Manual Table 1-1. Basic Settings screen fields Settings Description Domain Name Server (DNS) Address NAT (Net Address Translation) These fields Router MAC Address appear only if no login is required. The DNS server is used to look up site addresses based on their names. • Get Automatically from ISP. Your ISP uses DHCP to assign your DNS servers. Your ISP automatically assigns this address. • Use These DNS Servers. If you know that your ISP does not automatically transmit DNS addresses to the modem router during login, select this option, and enter the IP address of your ISP's primary DNS server. If a secondary DNS server address is available, enter it also. NAT automatically assigns private IP addresses (10.1.1.x) to LAN-connected devices. • Enable. Usually NAT is enabled. • Disable. This disables NAT, but leaves the firewall active. Disable NAT only if you are sure that you do not require it. When NAT is disabled, only standard routing is performed by this router. Classical routing lets you directly manage the IP addresses that the modem router uses. Classical routing should be selected only by experienced users* • Disable firewall. This disables the firewall in addition to disabling NAT. With the firewall disabled, the protections usually provided to your network are disabled. The Ethernet MAC address that will be used by the modem router on the Internet port. Some ISPs register the Ethernet MAC address of the network interface card in your computer when your account is first opened. They will then accept traffic only from the MAC address of that computer. This feature allows your modem router to masquerade as that computer by "cloning" its MAC address. • Use Default Address. Use the default MAC address. • Use Computer MAC Address. The modem router will capture and use the MAC address of the computer that you are now using. You must be using the one computer that is allowed by the ISP. • Use This MAC Address. Enter the MAC address that you want to use. *. Disabling NAT reboots the modem router and resets its configuration settings to the factory defaults. Disable NAT only if you plan to install the modem router in a setting where you will be manually administering the IP address space on the LAN side of the router. 1-7 Connecting Your Router to the Internet v1.0, November 2009
