No, but our firewall is a BSD box.  I did "arp -a" on that and
got a list of IPs and MACs, but none of them match the MAC address
that is causing the problem.

AFAIK, the only thing on our network that is NATing is the firewall
and the firewall is the only way to get out of our network. So my
understanding is that it it is on our network and is going outside,
it MUST be seen by the firewall.  Is that right?
