I removed lines 1 & 4.  I don't recall why I thought they were 
necessary.

Right on both ends.

I fixed both workstation and laptop arp tables using the arp -s 
command, but still no joy.  I do notice that both machines are
correct in the firewall's arp table.  Also, both now have M set
the flags column for the other machine.

I'm running an ethernet (Cat 5, RJ45), with a hub, which should be 
totally transparent.
