LogCop is a set of turn-key bash/firewall/awk scripts for enhancing an IDS. It monitors system logs and blocks IP addresses based on such criteria as illegal user names from repeated attacks. In production under Linux, FreeBSD, OS X, Solaris.
The goal of WallFire is to build a very general and modular firewalling application based on netfilter or any kind of low-level framework. It will provide a multi-language API, commandline and interactive tools as well as X11 or HTML front-ends.
This project wants to provide useful tools for routing simple small private networks using a dial-up or broadband link. These tools consist of firewall and traffic shaping tools currently. Any feedback is welcome.
...The binding allows direction manipulation of the iptables through an object oriented and transaction based manner.
The binding removes the need to call iptable on the commandline in python applications.
Frankenwall is a bash shell script intended to create a highly secure IPTables based linux firewall/router with QOS/traffic shaping/bandwidth management. Be certain you know EXACTLY what your network needs before using Frankenwall. Wimps need not apply.
Simple-to-use, dynamic, rule-based firewall addition. Uses QUEUE/userspace to dynamically approve or drop packets based on custom rules. With frequency caching, friend/foe indication, loose IP matching, and customizable logging.
IP Blocker is an incident response tool that automatically updates access control lists on Cisco routers and other devices. Web and commandline interfaces are both supported, as is logging, email notification, and automatic expiration of blocks.

Green Screen: A Linux based Advanced Syslog Server for Juniper NetScreen Firewalls - Can be expanded later to support other products. It can capture syslog messages, parse them, store them in a MySQL database. A Web GUI interface is also included.
A simple port-relaying program written in Java; sits on specified ports for either TCP or UDP, re-sends packets to the given IP. Doesn't forward packets, actually receives and re-sends them. Could be handy to learn Java Sockets/networking. Public Domain.
A replacement firmware distribution for the 3com 3CRADSL72 a.k.a 3com wireless 11g (distributed by Ya.com) and its identical twin, the SMC7804WBRA, with an ucLinux kernel based system and associated system tools.
Development area for GNU/Linux 2.6.x for the KS8695 ARM SoC. Covers kernel patches, drivers for serial, Ethernet, PCI, GPIO, watchdog subsystems, and drivers for optional PCI based devices such as USB, WiFi, WiMAX, IPSec, SSL, and RSA devices.
A dynamic Firewall (using the iptables netfilter) which can alter its is rules on detection of certain attacks/events. Very easily modified and expendable, with mySQL back-end and dynamically loaded user-space filters.
The Nemesis Project is designed to be a commandline based, portable human
IP stack for UNIX-like and Windows systems. The suite is broken down by
protocol, and should allow for useful scripting of injected packets from
simple shell scripts.
