I have no need for a LAN.  The firewall is at a datacenter and is protecting my web and mail
servers.  There is nothing else there.

The only reason I use the LAN port at all is because the PPTP in m0n0wall shows up on the LAN
side.... which cannot communicate with the DMZ (because it is bridged to the WAN)... so the servers
need to be on the LAN port as well for me to talk to them.

Keep it coming guys... I know we can figure something out.  And I really do appreciate the help!

Not addressing the question at hand, but dual homing all your hosts on
your DMZ and LAN, whether it's 2 NIC's or two IP's on one NIC, negates
one of the main purposes of having a DMZ in the first place -
protecting your LAN if a publicly accessible hosts gets compromised. 
I wouldn't recommend doing that under most any circumstance.  2 NIC's
is better than two IP's on one NIC, but not by a whole lot.
