MAC address of the NIC (or router). Brain spasm.

Hey, it's all alphabet soup anyway, right? ;>)

BTW, one should note that the cloning of a MAC address (done via the router) is only necessary if you have a box on the inet side of the router, aka DMZ. Seems to be far more common for cable folks to need to clone the MAC.
