Firewall by Jim 1.23Alpha (Development)
Saturday, September 14th 2002

Developer: Jim Gifford
License: Freely distributable.

About :
This is a firewall that takes advantage of tcp_wrappers information to block users. It also uses separate files for configuration ease. It is designed to work out of the box with eth0 for internet and eth1 for the LAN.

Changes :
Support for the ECN TCP Flag was added. Blocking and logging of OS footprints was added.


Purpose :
I got tired of all the firewall scripts out there that did not do what I wanted them to. I wanted a firewall that was flexible to use, but did it's job. I wanted one that can be configured to any circumstance easily without changing the script itself. That is why my Firewall was designed with separate text files for ease of configuration.

Protection :
I have built in multiple means of protection into the firewall itself. Of the most most notable is the hacker, trojan, spam, and blacklist capabilities.

Hacker :
The hacker protection will prevent the outsite world from running commands. If you choose to enable this function.

Trojan :
The trojan protection has two different levels. Standard and Intensive. The standard only protects from known linux and unix trojans. Where as, the intensive will protect from all known trojans, windows, linux, and unix based.

Spam :
The Spam protection will block any IP address that is listed from sending to your SMTP server.

Blacklist :
The blacklist protection will block total communications to a site. I have also included a blacklist update script which will pull blacklist information from Dshield.
