Vuurmuur is a powerful firewall manager built on top of iptables that works with Linux kernels 2.4 and 2.6. It has a simple and easy to learn configuration that allows both simple and complex configurations.
The configuration can be fully configured through an Ncurses GUI, which allows secure remote administration through SSH or on the console.
Vuurmuur has powerful monitoring features, which allow the administrator to look at the logs, connections and bandwidth usage in realtime. It makes use of IPTrafficVolume for keeping track of the traffic volume per interface.
The program is divided into three part. One element (the middle-end) converts humanly-readable rules, hosts, groups, networks, zones, interfaces and services into a iptables ruleset (or optional into a bash-script). The second element is a small daemon that converts the Netfilter logs to easy readable logs. The final element is an Ncurses-based user interface (the front-end) to manage the firewall.
