I didn't get any flame for stating; a dual-subnet attached NT webserver
was an O.K. solution, where one can't get past the TCP/IP NT system 
onto a NETBEUI/IPX network unless the webserver had access to internal 
systems.  Hmm.

Let me make another statement:
"If systems in a company's network use challenge/response authentication 
and password encryption for all connections (such as where NT is headed), 
there isn't justification for a firewall anymore.  Traditional Firewalls 
are designed for UNIX environments where plaintext or unprotected 
applications live, such as telnet/ftp/smtp/popmail/xwindows."

Hmm.  Maybe next-generation firewalls will need to look at application/
RPC transactions that desktop/server PCs use instead of just network port
number traffic.
