PeerGuardian - a privacy oriented firewall application
PeerGuardian is a privacy oriented firewall application. It blocks connections to and from hosts specified in huge blocklists (thousands or millions of IP ranges). Its origin seeds in targeting aggressive IPs while you use P2P. PeerGuardian Linux: Actively developed. However the team is very small and with few spare time. Contributors are welcome! Peerguardian OS X: Not developed anymore. We've lost contact with the OS X developer. New contributors are welcome! PeerGuardian Windows: Not developed anymore. It's highly recommended to use PeerBlock instead, which is a continuation of PeerGuardian's development in Windows, with bug fixes and support for Windows Vista and Windows 7. New contributors and/or collaboration with peerblock.com are welcome! PeerGuardian is an open project. Not only is its source code open for you to read, use, and modify - but the project is open for you to join and contribute in any form (code, documentation, bug reports, web and support).
A powerful network security tool, easy, safe and totally free.
BrazilFW is a mini Linux distribution designed to be used as a Firewall and Router that runs easily on older computers. An old PC running BrazilFW is much more powerful and efficient than commercial software for routing in offices and residences running on a "powerful" computer. BrazilFW is based on Coyote Linux, which was designed by Joshua Jackson who discontinued Coyote Linux in version 2.24 in August 2005. In that same month comes on the scene BrazilFW Firewall and Router (BFW) with version 2.24, which is led by "Claudio" and "Marcelo - Brazil", running only on floppy disks, and being 2.30.1 the last version with this support . The following versions, as well having automatic detection of network cards, only run on large capacity media, such as hard disk (HD). Versions in Development: * 2.33.x: Uses kernel 2.4.x and is developed by Marcinho Samurai. * 3.x: Uses kernel 4.x and is developed by WoshMan

360-FAAR Analyze FW1 Cisco Netscreen Policy Offline Using Config/Logs
360-FAAR (Firewall Analysis Audit and Repair) is an offline, command line, firewall policy manipulation tool to filter, compare to logs, merge, translate and output firewall commands for new policies, in Checkpoint dbedit, Cisco ASA or ScreenOS commands, and its one file! Read Policy and Logs for: Checkpoint FW1 (in odumper.csv / logexport format), Netscreen ScreenOS (in get config / syslog format), Cisco ASA (show run / syslog format), 360-FAAR compares firewall policies and uses CIDR and text filters to split rulebases / policies into target sections and identify connectivity for further analysis. 360-FAAR supports, policy to log association, object translation, rulebase reordering and simplification, rule moves and duplicate matching automatically. Allowing you to move rules to where you need them. Build new rulebases from scratch with a single 'any' rule and log files, with the 'res' and 'name' options. Switch into DROPS mode to analyse drop log entries.

Easy to use firewall for linux beginners.
New improved iptables tool, based on my earlier project Easy Linux Firewall, but rewritten from scratch using Perl. It's a simple rewrite for now, but i am working on adding some new features like. Some of the improvements will be web administration panel, automatic filtering daemon, TCP listener providing easy to use API so you can integrate it on many servers and centralize them in to one Web interface to control all of them. I am open to new ideas and also any kind of contributors, because I'm working on this alone and it isn't easy, so you are welcome to help.

Network Firewall Linux Kernel Module with Conflict Resolution Engine
We implement an open source conflict resolution framework that consists of a user-space C application that automatically resolves firewall rules anomalies, and b) a generic tree (called policy tree), implemented as a Linux kernel module which maintains the resolved firewall rules and enables the necessary hooks to netfilter for matching incoming (or outgoing) network packets. Tree-based data structures offer improved efficiency compared to traditional access control lists (e.g. iptables or nftable maps), especially for large systems with a huge number of rules. Preliminary analysis from our implementation on ARM-based embedded systems examines efficiency and scalability of our framework.
