I believe (someone correct me) that there will only be an entry in the
ARP table if a connection was established between the client and the
m0n0wall. A UDP Broadcast is not a connection. The entry shows up in the
logs, but that is just because something unusual has occurred (a machine
is broadcasting on a different subnet than the m0n0wall LAN subnet)
