There are couple of free and open source firewall which are  so good to protect your home or office network from any kind of attacks which may be a virus attack or human initiated one.  Here we are going to discuss about an open source firewall called smoothwall which is very easy to install and configure.

What is smoothwall ?

The SmoothWall Open Source Project was set up in 2000 to develop and maintain SmoothWall Express – a Free firewall that includes its own security-hardened.SmoothWall Express is an open source firewall distribution based on the GNU/Linux operating system. Designed for ease of use, SmoothWall Express is configured via a web-based GUI and requires absolutely no knowledge of Linux to install or use.

SmoothWall Express enables you to easily build a firewall to securely connect a network of computers to the Internet

Almost any Pentium-class PC can be used, for example, an old low specification PC long redundant as a user workstation or server. SmoothWall Express creates a dedicated hardware firewall, offering the facilities and real security associated with hardware devices.
SmoothWall Express comes pre-configured to stop all incoming traffic that is not the result of an outgoing request. The rules files that implement this policy are part of the system configuration and should not normally be edited by other than the configuration procedure.
