RE: NT Authentication over Debian Firewall/Router

	I'm just going to throw out some random guesses that might actually hit the
right thing.  I would look at forwarding traffic from port 139 (+/-, netbios
anyway) from your PDC through the firewall to your now rouge NT box (you
probably want to be VERY specific and careful about it).  You might also
want to think about doing something with the broadcast address traffic on
that same port (Windows loves to broadcast).  How many users will access the
box?  Have you thought about removing the NT box from the domain (making it
only accountable to a workgroup), and making it a stand-alone server using
it's own security?

Random guesses free of charge,
