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.

. 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

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
.
Note:
For information about how to install ADSL filters, see the
Wireless-N ADSL2+
