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 project to work on and we have truly appreciated all the support and positive feedback that the user community has provided. Without you we wouldn’t have been able to keep things going this long. You might be wondering why we are doing this... We had an exciting opportunity come up to start a company developing advanced security automation solutions. This was a chance of a lifetime that we just couldn’t pass up and unfortunately it means that we no longer have time available to work on improv
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

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.
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.
Windows Port Knocking. A Windows implementation of port knocking developed to work alongside an existing firewall (the free CHX-I Packet Filter v3.0).
FirewallPAPI is an open source firewall for Windows 2000 and above. It is a simple utility for filter network traffic.
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.
VTD-XML is the next generation XML parser/indexer/editor/slicer/assembler/xpath-engine that goes beyond DOM, SAX and PULL in performance, memory usage, and ease of use.
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.

Debian packages for PeerGuardian Linux (including the GUI) and its precessor moblock/blockcontrol/mobloquer. 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 origins lie in targeting aggressive IPs while you use P2P. See http://sourceforge.net/projects/peerguardian/
iSafer firewall is used to protected your PC against spywares, spamwares. It is also a good example for software developers to understand the basic knowledge about firewall. NOTE: Visit http://isafer.sourceforge.net to see more...

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.
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.
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.
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.
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.
sbills is an Internet traffic monitor. If, for example, you have a local network with a Linux server that provides users with Internet access, it allows you to control Internet traffic.
