We prevent ANY packets to or from our network with a broadcast
address. We don't filter on a per-machine basis for address
spoofing, but ALL packets leaving our network must have a valid
address on our network. Basically, one user on our network can spoof
another user on our network, but no users can spoof addresses that
are not on our network.
