address.

Password

The password that you use to log in to your ISP.

Idle Timeout (In minutes)

If you want to change the login time-out, enter a new value in

minutes. This determines how long the modem router keeps

the Internet connection active after there is no Internet activity

from the LAN. Entering an Idle Timeout value of 0 (zero)

means never log out.

Internet IP

Address

•

Get Dynamically from ISP

. Your ISP uses DHCP to assign

your IP address. Your ISP automatically assigns these

addresses.

•

Use Static IP Address

. Enter the IP address that your ISP

assigned. Also enter the IP subnet mask and the gateway IP

address. The gateway is the ISP’s modem router to which

your modem router will connect.

This field appears only if

no login is required.

•

Use IP Over ATM (IFoA)

. Your ISP uses Classical IP

addresses (RFC 1577). Enter the IP address, IP subnet

mask, and gateway IP addresses that your ISP assigned.

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

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.

These fields

appear only if no

login is required.

Router MAC Address

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.

ADSL Settings

The default ADSL settings of your modem router work fine for most ISPs. However, some ISPs

use a specific multiplexing method and virtual circuit number for the virtual path identifier (VPI)

and virtual channel identifier (VCI).

If your ISP provided you with a multiplexing method or VPI/VCI number, then enter the setting:

1.

From the main menu, select ADSL Settings.The ADSL Settings screen displays.

2.

In the

Multiplexing Method

drop-down list, select

LLC-based

or

VC-based

.

3.

For the VPI, type a number between 0 and 255. The default is 8.

4.

For the VCI, type a number between 32 and 65535. The default is 35.

5.

Click

Apply

.
