Best Linux Firewalls

According to Wikipedia, A firewall is a part of a computer system or network that is designed to block unauthorized access while permitting authorized communications. It is a device or set of devices which is configured to permit or deny computer applications based upon a set of rules and other criteria. In this post, I am going to talk about the software firewalls

1. IPCop – http://sourceforge.net/apps/trac/ipcop/wiki

The best, but could be better if they improve the interface a bit

2. ClearOS Enterprise – http://www.clearfoundation.com/Software/overview.html

It is a well-balanced and appropriately featured firewall.

3. eBox Platform – http://www.ebox-platform.com/

The interface is dull, but offers so much more than an ordinary firewall

4. Monowall – http://m0n0.ch/wall/

Nifty if you use embedded systems. Not brimming with heaps of features, but gets the job done.

5. PfSense – http://www.pfsense.org/

Just serious firewall. Nothing else

Special mention – Smoothwall Advanced 2 – Great, but is its 1250 pound price tag worth it?
