Well, after having spent 3 days pounding on this, I finally found a bad
ethernet cable that was causing all sorts of funky behavior.  Replacing
the cable and rebooting the m0n0wall fixed the DMZ issues I was having.
Server NAT is working fine.  The cutover to the m0n0wall setup from
the old linksys NAT box was otherwise painless.  Network downtime for
clients was less than 2 minutes.

The client is extremely pleased with the result.
