I have done some limited testing on this subject. They way I got 
around it was this:
1) set a rule on the masq box that looks like this (1.2.3.4 is 
"public" subnet):
   ipfwadm -F -a accept -S 1.2.3.4/24 -D 192.168.1.0/24
This allows any connections from the public subnet back across to 
the masq'd network without any masquerading. 
2) manually add a route to the route tables on the PDC and/or BDC 
(which are on the public subnet) to the 192.168.1.0 net with the 
gateway being the public address of the masq box.

Of course, using a wins server is required, as others have 
suggested. This allowed me to do domain logins.

I would think you could also add the route back to the masq'd 
network at your main router or firewall, to keep from having to put 
manual routes in on your PDC/BDC's, and other machines.

HTH,
Doug
