firewall server routing setup
Thanks for the input. I have a difficult situation that needs all help.
currently setup is WAN router connect to a switch, then all workstations connect to switch, router and workstation are using same subnet, like 168.1.X.X
What I want is to setup a firewall server (2 NIC cards) between Router and swith.
how do I setup this firewall without changing WAN router configuration? Another word, if this case, two NIC cards will have same IP subnet, but how is routing going to work?
