Firewall Builder consists of object-oriented GUI and set of policy compilers for various firewall platforms. In Firewall Builder, firewall policy is a set of rules, each rule consists of abstract objects which represent real network objects and services (hosts, routers, firewalls, networks, protocols). Firewall Builder helps user maintain database of objects and allows policy editing using simple drag-and-drop operations. Firewall Builder can be used to manage firewalls built on variety of platforms including, but not limited to, Linux running iptables and FreeBSD or Solaris running ipfilter.
1a31df4d7c6ddcbe9aa7ae861ea438d2iptables is the new packet alteration framework (firewall utility) for Linux 2.4. It is an enhancement on ipchains, and is used to control packet filtering, Network Address Translation (masquerading, port forwarding, transparent proxying), and special effects.
0a5f5f226e41ce408a895bec995e8c05Vuurmuur is a middle-end and front-end for netfilter and iptables that is aimed at system administrators who need a decent firewall, but do not have netfilter specific knowledge. It converts human-readable rules into an iptables ruleset (or optional a bash script), makes netfilter logs readable, and includes an ncurses GUI.
a9adc264e27cbe48bc36e9c815b88148NARC (Netfilter Automatic Rules Configurator) is a free firewalling package for Netfilter/Iptables, released under the BSD license. It attempts to simplify the setup of a firewall (stateful packet filter) via the iptables tools. It is a bash shellscript that generates (hopefully) sensible and secure rules for Netfilter based on a simple configuration file. It features quick setup via a simple configuration file, connection tracking (and fragmentation reassembly), customized logging, probe detection (TCP and UDP), and much more.

It is ideal for masquerading and securing networks on ADSL and cable lines, using static IP, DHCP, and PPPoE. Installation involves editing of only one file on the floppy.
dd96b97973234e25e98db5702514bcadThe etherdam utility is an IPTables firewall configuration engine. It implements a primitive scripting language as an alternative to the direct use of iptables. It comes with full documentation plus a heavily commented example configuration file. The configuration file should work for many scenarios with minimal adjustment.
7c7f12a7ff47bc10b6f8e09cae9a1b87FireHOL a simple yet powerful way to configure stateful iptables firewalls. It can be used for almost any purpose, including control of any number of internal/external/virtual interfaces, control of any combination of routed traffic, setting up DMZ routers and servers, and all kinds of NAT. It provides strong protection (flooding, spoofing, etc.), transparent caches, source MAC verification, blacklists, whitelists, and more. Its goal is to be completely abstracted and powerful but also easy to use, audit, and understand.

6832b14f64c25b9c0394a76169ff98b4P2P Privacy Guardian is a Perl script that downloads a list of malicious IP addresses and denies incoming and outgoing connections to addresses on the list via IPTables.
64cab99f19f80c226eb57ed1a21bc7abUIF, or Userfriendly Iptables Frontend, is used to generate optimized iptables packet filter rules, using a simple description file specified by the user. Generated rules are provided in iptables-save style. UIF can be used to read or write rulesets to or from LDAP servers in your network, providing a global storing mechanism. Its aim is to be an easy to configure, human readable packet filter.
4646fe111559b22a1918f951ab981355Jay's Iptables Firewall is a bash script that allows one to easily install and configure a firewall on a Linux system. It features support for multiple interfaces, TCP/UDP/ICMP control, masquerading, synflood control, spoofing control, port forwarding from specific interfaces, VPNs, ToS, denying hosts by IP or MAC address, ZorbIPTraffic, Spyware list IP, Pre/Post scripts, log options, and more. The firewall is able to launch custom iptables rules, and the configuration of the firewall is assisted by an optional, interactive, curses-based Perl script.

c0c86c5d0a2f6eeff388c66d49c63463Knetfilter is a KDE frontend to iptables which is used with Linux 2.4 to manage the functionality of netfilter. Knetfilter lets you set up most common firewall configurations, as well as perform more sophisticated management of a complex firewall. It's also possible to use an integrated interface to tcpdump and nmap. Screenshot available here.
