NETGEAR MBR814X Reference Manual page 29

Classical routing lets you directly manage the IP addresses the MBR814 uses. Classical
routing should be selected only by experienced users.
Note: Disabling NAT will reboot the router and reset all the MBR814X configuration
settings to the factory default. Disable NAT only if you plan to install the
MBR814X in a setting where you will be manually administering the IP address
space on the LAN side of the router.
4. Router MAC Address:
This section determines the Ethernet MAC address that will be used by the router on the
Internet port. Some ISPs will register the Ethernet MAC address of the network interface card
in your computer when your account is first opened. They will then only accept traffic from
the MAC address of that computer. This feature allows your router to masquerade as that
computer by "cloning" its MAC address.
To change the MAC address, select "Use this Computer's MAC address". The router will then
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. Alternatively, select "Use this MAC address" and
enter it.
