Im just wondering, Im trying to make the office lan more secure so I was thinking of setting up a box running red hat linux and making that box serve as a firewall for the server? the server is running windows 2003 server but will be soon upgraded to Small Business Server 2003..there are about 24 clients connected to the server running windows XP,
So can i setup a box running linux that will protect the windows 2003 server? make it act like a router?
Any information on how I can do this would be great,
