A firewall does not guarantee security but it is in most environments the first line of defense against network based attacks.
You can use Firestarter on your…

… desktop or laptop. Our philosophy of simplicity has made Firestarter the most widely used Linux desktop firewall software available today.

… server. Firestarter can be installed onto individual servers and managed graphically over SSH or using the shell.
