NAT allows computers on your home network to share the modem router Internet connection. NAT is
enabled by default because it is required in most situations. Select the NAT setting:
• Enable. NAT is enabled. This is the default setting. Leave this setting if no reason to disable NAT
• Disable. NAT is disabled.
Router MAC Address
The Ethernet MAC address that the modem router uses 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 accept
traffic only from the MAC address of that computer. This feature allows your modem router to use your
computer’s MAC address (also called cloning).
Use Default Address Use the default MAC address.
Use Computer MAC Address The modem router captures and uses the MAC address of the computer
that you are now using. You must use the one computer that is registered
by the ISP.
Use This MAC Address Enter the MAC address that you want to use. By default, the field displays
the MAC address of the Internet port.
