Subject: Windows NT servers in different networks and firewall

Just when we are all getting a warm snug feeling with TCP/IP, Windows NT 
jumps out to hit us over the head with its TCP/IP - IPX - NetBios 
multiple stack.   

Given the ease with which it is possible to do IP spoofing with 
commercially available software and a publicly available sniffer, 
I wonder what can be done to effectively firewall two Windows NT servers 
that each live in a different network but share a common user population 
between the two networks.

The firewall would have to handle authentication, file and print services 
and rpc calls.

Which vendors, if any, supply a firewall with these capabilities for 
Windows NT servers?
