FC2 comes with a firewall. It uses what is called IPtables (which is how you build a firewall in Linux).

If you want to modify your firewall you can learn IPtables or download Webmin (www.webmin.com). There is also a tool called Firewall Builder that may help you out.

Good luck!

Also Bastille Linux helps you to harden your box, but it is a little hard to install.

The linux kernel has an excelent firewall built in. Fedora has a graphical config utility in th emenu under System settings - Security level.

For steps to configure the firewall from the command line, see http://www.dummies.com/WileyCDA/DummiesArticle/id-2597.html

That page gives you a firewall which allows all traffic out from your computer, but doesn't allow any in to it except what is required to use the Internet. I believe the highest security setting on Fedora CORE 2 gives you basically the same level of security.

Shorewall is definitely a good choice of firewall, though you have to understand how it all comes together if you are new to Linux and IPtables. However there is a pretty secure and simple to setup firewall script I use, which sets up IPtables by just editing a single configuration file. you can get it at http://www.malibyte.net/iptables/scripts/fwscripts.html

I used to 'roll my own' with RedHat 8 and iptables on a Pentium II PC with two extra network cards, supporting DMZ. However, now I have used Smoothwall Express in production for a couple of years, on the same hardware, with DMZ, without having to use vi at the command level.

"SmoothWall includes a hardened subset of the GNU/Linux operating system, so there is no separate OS to install. Designed for ease of use, SmoothWall is configured via a web-based GUI, and requires absolutely no knowledge of Linux to install or use"
