Vuurmuur – powerful firewall manager built on top of ​iptables

Vuurmuur is a powerful firewall manager built on top of iptables on Linux.

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.

Features include:

Administration

  • No iptables knowledge required.
  • Humanly readable rules syntax.
  • Ncurses GUI, no X required.
  • Portforwarding is made very simple.
  • Easy to setup in with NAT.
  • Secure default policy.
  • Entirely manageble through ssh and from the console.
  • Scriptable for integration with other tools.
  • Can produce a bash firewall script.
  • Anti-spoofing features.
  • Killing of unwanted connections.
  • Supports working with Snort_inline using QUEUE or NFQUEUE.

Monitoring
