I am trying install a software firewall in our lab. How I am planning to do this is by, installing a firewall application on a computer. There are two network adapters attached to this pc, one is connected to the internet router and the other is connected to the router wan port, and then it goes to the switch for 120 pc's.
I have Bridged two network adapters and I can access the internet via the client pc's. When I set some rules on the firewall, its working with the server, but not with the client pcs. I tried to block all internet from client router ip, and it's not working.
This is a small setup, so I tried with Comodo free firewall as well as Windows firewall, neither are working correctly.
