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.
