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.

Check my blog for an iptables and webmin tutorial:

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.

Works like a charm. Safe, secure, reliable.

IPCop, ClarkConnect can be used for this.
ClarkConnect is based on RedHat.

Please use the Shorewall. It is good firewall to protect your network from outside hackers. here are some links of shorewall

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"

More info: http://smoothwall.org
