Gibraltar Firewall 2.6, a Linux firewall distribution based on Debian, was launched yesterday as announced by Rene Mayrhofer. This will be the last release that will use the Linux kernel 2.4, as the next Gibraltar editions will use the 2.6 kernel. Among other things, this edition of Gibraltar offers improved traffic shaping performance (the iptables marking rules were re-ordered and the pre-defined traffic classes were improved), and allows SSL Explorer plugins to be installed. Have you ever used the Gibraltar Firewall? Gibraltar provides the user with a web interface for setting up their firewall. Now it's available for the Linux 2.6 kernel. Also in this release they added full WLAN access point functionality.

The Shoreline Firewall, more commonly known as "Shorewall", is a high-level tool for configuring Netfilter. You describe your firewall/gateway requirements using entries in a set of configuration files. Shorewall reads those configuration files and with the help of the iptables utility, Shorewall configures Netfilter to match your requirements. Shorewall can be used on a dedicated firewall system, a multi-function gateway/router/server or on a standalone GNU/Linux system. Shorewall does not use Netfilter's ipchains compatibility mode and can thus take advantage of Netfilter's connection state tracking capabilities. https://www.shorewall.net/ Shorewall is a great firewall package for Linux it's, most distro's have packages available.
