What it sound like you need to do to have the firewall only see the server is
set-up ISA server, install a 2nd network card, and completly redo the network
set-up, that way all internet requests would be processed through the server.
 Right now the server is redirecting the clients to the firewall because (I
assume.) that the server's gateway is the ip for the firewall, (10.0.0.250).
Quite honestly it would be easier and less time consuming to buy the licenses
for the firewall.
