Disable NAT only if you plan to set up the wireless modem router in a setting where you will be manually
administering the IP address space on the LAN side of the router.

ADSL Settings

ADSL settings of your wireless 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).
Note: You must use the Setup Wizard to select the correct country for the
default ADSL settings to work.
Description
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 you do not need it. When NAT is disabled,
only standard routing is performed by this router. Classical routing
lets you directly manage the IP addresses that the wireless modem
router uses. Classical routing should be selected only by
1
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 used by the wireless modem router on
the Internet port. Some ISPs register the 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 wireless modem router to use
your computer's MAC address (this is also called cloning).
• Use Default Address. Use the default MAC address.
• Use Computer MAC Address. The wireless 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.
