Armand - your question indicates the confusions since it is unclear what you
are asking.

Apparently, you have a dual-NIC Windows NT (MS Proxy Server?)
IP Address (public) 24.116.64.118
IP Address (private) 192.168.1.200

and a linux computer
IP Address (private) 192.168.1.200 (same as Windows NT Server?)
IP Address (private) 192.168.0.200 (where does this go?)

and significantly -
gateway address 192.168.0.1 (what computer/hardware is this?)
dns server 192.168.0.25 (is this another computer that's a caching dns
server?)

so first, I gotta ask...
why the two private lan networks...192.168.0. & 192.168.1.?
then I gotta ask...
if the Windows NT Server is already exposed to the internet, what role does
the linux firewall play?
