ufw

ufw (Uncomplicated Firewall)
Create a tool for host-based iptables firewall configuration. This tool should provide an easy to use interface to the user, as well as support package integration and dynamic-detection of open ports.

除了firestarter外，另一款沒腦設定iptables的方式

這是在Ubuntu相關的介紹看到的套件

使用Debian時，卻發現另一個套件nufw(per-user firewalling daemon that interfers with libipq)
用法大不同，ufw算是不用gui介面(firestarter)也能輕易寫出防火牆規則的方法之一
