      Think of a firewall/router such as the dlink model I referred to as a
border between what I think of as the "outside world" and the
"inside world". The outside world see's the spoofed (duplicated)
MAC address, while the inside world sees the true MAC address.  Thus
neither identical MAC address sees itself.

      Make sense now?
