One Host "Karate" Firewall Howto |
|
This document describes how to secure your Linux machine that is placed in an untrusted environment and has to fare on its own for its protection. Examples may include an unfirewalled network , a poorly firewalled network, or a well firewalled network that is so poorly managed inside, that you do not trust the insiders. |

The unofficial Linux ipchains-HOWTO |
|
This (unofficial) HOWTO was written in order to help clarify the use of the new ipchains program, which is used for IP
firewalling/packet filtering under Linux 2.1 and 2.2. I found the official HOWTO very theoretical, giving few concrete examples. This HOWTO will not focus on theory, it will instead focus on getting things done. |

IP Filter Based Firewalls HOWTO |
|
IP Filter is a neat little firewall package. It does just about everything other free firewalls (ipfwadm, ipchains, ipfw) do, but it's also portable and does neat stuff the others don't. This document is intended to make some cohesive sense of the sparse documentation presently available for ipfilter. |

T.REX: Open Source Firewall |

The T.REX Open Source Firewall was released to provide users with a cheap (or free if downloaded) security suite. With all the features of a high-end firewall (such as: load balancing, high availibility, web caching, etc), as well as the availibility of commercial support (from per-incident, to full-year support contracts), T.REX is a useful tool for a wide range of users. |

Mason Firewall Builder |
|
Mason is a tool that interactively builds a firewall using Linux' ipfwadm or ipchains firewalling. You leave mason running on the firewall machine while you are making all the kinds of connections that you want the firewall to support (and want it to block). Mason gives you a list of firewall rules that exactly allow and block those connections. |

Falcon Firewall Project |
|
The Falcon (Free Application Level CONnection) project is a project to design a free, secure and OS independent firewall. Falcon consists of different modules: their own proxies, SQUID for web access, BIND 8 for nameservice, Qmail for mail handling and a certain amount of OS hardening (which has not yet been implemented). |
