|
Domain Name Server (DNS) Address | 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 (Net Address Translation) | NAT automatically assigns private IP addresses (10.1.1.x) to | |
|
| |
|
| • 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. |

|
These fields | Router MAC Address | The Ethernet MAC address that will be used by the modem |
appear only if no |
| router on the Internet port. Some ISPs register the Ethernet |
login is required. |
| 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.
