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 Outdated technology.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:
Not developed...

Firewall Builder is a GUI firewall management application for iptables, PF, Cisco ASA/PIX/FWSM, Cisco router ACL and more. Firewall configuration data is stored in a central file that can scale to hundreds of firewalls managed from a single UI.
A message from project maintainers:
After working on Firewall Builder for many years it is with some sadness that Vadim and I are announcing that we have suspended all development activity for this project. Firewall Builder has been a great...
New customers can spin up VMs, build with AI, and query data at no cost.
Put your $300 in credit toward real workloads, then keep building with free monthly usage for 20+ products. No commitment and no charge until you upgrade.
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.
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.
Anoubis is a Security Suite which implements a secured environment for applications. The core of the suite is an Application Firewall alongside with a Sandbox. Mechanisms to assure the authenticity of files, directories and applications are provided.
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.
BrFW is an application firewall, the user will specify what programs are able to open sockets (RAW / IP / UDP / TCP...).
BrFW alerts when another program try to access the network.
The WRT54GL Tarifa enhanced firmware. Linksys WRT54G/WRT54GS models V1 to V4 and the WRT54GL V1.x This Third Party Firmware is functionaly the same as the original, the improvements are to make this router more scaleable, by increasing the capacity.
sshh allows you to make a persistent tcp connection (tunnel) over an http proxy. Once you have it set up, you can make new connections from either end. Similar in concept to httptunnel but more versatile and scalable.
KMyFirewall is a KDE/Qt Programm that tries to provide an easy to use and comfortable GUI for the Linux "iptables" command. An easy to use plugin architecture allows fast and easy development of rule option extentions.
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.
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.
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
SmartDog is anti-spam,intrution detection software for windows/linux. And, it contains many features that are all requried by a normal user to network administrator.

Live Security/Forensics Linux Distribution, built from scratch and packed full of tools useful for vulnerability analysis, penetration tests, and forensic analysis.
Firewall-Rulegenerator creates automatically iptables-scrips from XML-Files containing Information
on your network-topology and your required services.
The SWAP (Secure Wireless Access Point) project is intended for use in embedded appliances. These appliances will operate in the role of a WEP (wireless encryption protocol) and IPSEC enabled wireless access point, IPSEC VPN gateway, and firewall.
Guarddog is user friendly firewall management utility for KDE on Linux. It allows you to simply specify which protocols should be allowed between which groups of computers and requires no knowledge of port numbers or packets. Uses ipchains or iptables.
