Supported Firewall Projects

Ferm Support & Consultancy

ferm is a tool to maintain complex firewalls, without having the trouble to rewrite the complex rules over and over again. ferm allows the entire firewall rule set to be stored in a separate file, and to be loaded with one command. The firewall configuration resembles structured programming languages, which can contain levels and lists.

iptables Support & Consultancy

iptables is the userspace command-line tool used to configure packet filtering under Linux 2.4 and 2.6. Every firewalling solution for Linux is based in some way upon this tool.

Shorewall Support & Consultancy

Shorewall is a high-level tool for configuring iptables rules. It is a straightforward way of setting up a firewall.Shorewall is mainly used in network installations (as opposed to a personal computer firewall), since most of its strength lies in its ability to work with "zones", such as the DMZ or a 'net' zone. Each zone would then have different rules, making it easy to have for example relaxed rules on the company intranet, yet clamp down on traffic coming in from the internet.
