Smoothwall is a best-of-breed Internet firewall/router, designed to run on commodity hardware and to provide an easy-to-use administration interface to those using it. Built using open source and Free software, it's distributed under the GNU Public License.
A utility for detecting and resisting BIDIRECTIONAL ARP spoofing. It can anti-spoof for not only the local host, but also other hosts in the same subnet. It is as well a handy helper for gateways which don't work well with ARP.
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.
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:
Not developed actively anymore. Team might still be around. Some unreleased changes on git. Outdated technology.
Peerguardian OS X:
Not developed anymore. We've lost contact with the OS X developer.
PeerGuardian Windows:

The BACnet Firewall Router (BTR) is an application that combines BACnet routing capability with traffic management functions to carefully control access to building automation and control networks.
Debian packages for PeerGuardian Linux (including the GUI) and its precessor moblock/blockcontrol/mobloquer.

Easily turn a Ubuntu-based computer into a full linux router, complete with dhcpd, named/bind, iptables firewall, and packet inspection of the network traffic being routed.
Deep packet inspection for layer 2 (mac), layer 3 (ipv4, ipv6), layer 4 (icmp, tcp, udp), and layer 7 (application-specific). Summary of network flows and all layers of inspected traffic is stored in a database at 1-second intervals.
Creates true post-admission network access control by regulating network access to admitted users on an as needed basis. Users cannot escalate privileges between micro-perimeters. Manageable, efficient and scalable for complex security environments.
Sphirewall is a user centric analytical network firewall/router, its the only open source product that provides user/group and role based firewall rules with extensive reporting services
Deploy in 115+ regions with the modern database for every enterprise.
MongoDB Atlas gives you the freedom to build and run modern applications anywhere—across AWS, Azure, and Google Cloud. With global availability in over 115 regions, Atlas lets you deploy close to your users, meet compliance needs, and scale with confidence across any geography.
IPFIRE-wall is a framework that implements a network firewall. It can be used in desktop systems and in simple network configurations, providing a friendly graphical interface and a simple installation procedure. Also unprivileged users can personalize.
Net-Policy is a highly-scalable, role-and-policy based network management system. Net-Policy aims to be an easy-to-use, full-fledged management station capable of configuration, monitoring, and notification collection and aggregation via the use of SNMP
A simple NAT(network address translator) for IPv6 (Linux only). Make sure if you really need it before using it. Functions: 1. IPv6 auto configuration; 2. TCP, UDP and ICMP-Echo port forwarding; 3. static port mapping for TCP and UDP.
This project will serve as a central hosting/bug tracking center for modifications to the SmoothWall.org firewall distribution. Support and information for the "mods" posted here can be found on the SmoothWall.org forums, the SmoothWall.org IRC server, or
iplist is a list based packet handler which uses the netfilter netlink-queue library (kernel 2.6.14 or later). It filters by IP-address and is optimized for thousands of IP-address ranges.

GreenSQL is a database firewall engine used to protect Open Source Databases from SQL injection attacks. It works in proxy mode. Application logic is based on evaluating of SQL commands using risk score factors, as well as blocking of sensitive commands
Ptcap is a Unix daemon that captures traffic packet size, source, destination, and times and saves this data into a postgres (and now ODBC including mysql) database in near real time, from which traffic reports may be made.
This is a daemon that emulates Microsoft's Internet Connection Service (ICS). It implements the UPnP Internet Gateway Device specification (IGD) and allows UPnP aware clients, such as MSN Messenger to work properly from behind a Linux NAT firewall.
TRAP is a very innovative and advanced transparent proxy that verifies the integrity of your network communication. It offers a custom scripting language that allows the user full control over the decision making process.
l7f stands for "Layer7Firewall" which is a firewall-system, that protects your application on any protocol and fits its security needs flexibly. It can be used for example as web-application firewall.
Allows users of a Linux workstation to control which programs access the Internet. This can be done statically by listing them in a file or dynamically via a GUI dialog box that appears when a new program attempts to connect to the Internet.
HTTP Tunnel that works with ANY HTTP proxy: no CONNECT method required! You can use the port redirector or Socks 4/4a/5 to connect outside your (restricted) LAN. An external web server is required, to be used as gateway.
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, command line and interactive tools as well as X11 or HTML front-ends.
We have just released a new set of files.
This project will consist of a module for Firewall Builder. This module will be an add-on to Firewall Builder that will allow a user to create, compile, and apply firewall rules to a machine with Netnice Packe
SynAckFlood protect your linux box from portscan attacks, make a ficticious responce parallel to kernel, and portscanner show you that all ports are openned
