Paranoid Penguin - Linux Firewalls for Everyone

Need a personal firewall, an enterprise Internet gateway or something in between? iptables does it all!
Conclusions

A couple years ago, Linux Journal named iptables its Security Tool of the year. It really is a remarkable achievement. If you're serious about network security, you'll want to explore iptables' power in much greater detail than we've done in this article, starting with the iptables(8) man page and progressing through the how-tos available on the Netfilter home page (see Resources).

Whether you use iptables to protect your laptop or your entire enterprise network, I hope you've found this introduction useful. Be safe!

Mick Bauer (darth.elmo@wiremonkeys.org) is Network Security Architect for one of the US's largest banks. He is the author of the O'Reilly book Linux Server Security, 2nd edition (formerly called Building Secure Servers With Linux), an occasional presenter at information security conferences and composer of the “Network Engineering Polka”.

As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.
