Firewall consistency with Firewall Builder

(This article was edited by Mike Horn)

In the past I've already published articles and interviews on FSM about Firewall Builder (or FWB in short). The reason is simple: the tool kept evolving during the years, improving the features it already had and adding interesting new ones.

During these years I've not being using the tool regularly since I am not a Network Administrator. But I can say that every time I had a firewalling problem at hand, where I needed to prototype and test iptables configurations quickly, this tool never betrayed me!

This time we'll talk about how FWB helps you to configure multiple firewalls in a consistent way. We won't be talking about firewalling per se, so you can still benefit from reading this article even if you don't have deep firewalling, networking or security knowledge.

The examples in this article are based on Firewall Builder v4.2. NetCitadel recently announced the release of Firewall Builder 5 which includes some minor changes in the GUI, so some screenshots in this article may look slightly different from what you would see in v5.

Howto: Share mobile broadband in Ubuntu using only the GUI

Like many people who aren't able to get DSL, I use mobile broadband. Typically, at least in Ireland and the UK, you are forced to purchase a modem with your contract. What if you want other devices in your house to use this broadband and you don't want to fork out several hundred wing wangs for a mobile broadband router like the Novatel MiFi when you have a perfectly good modem and wireless router already? In Ubuntu you can setup the modem-connected machine as a robust router/firewall using the in-built Network Manager, Firestarter, and optionally, Gadmin DHCPD.

Firewall Builder: an interview with Vadim Kurland

About two years ago I published an article about Firewall Builder. Now that the version 3.0 is out I had a catch-up interview with its creator, Vadim Kurland, and I discovered a number of new interesting features.

MM: Hi Vadim, and thanks for answering my questions. You are the main author of Firewall Builder (FWB), but your name seldom appears even on the website www.fwbuilder.org. So, just before we start diving deep in FWB, would you like to briefly introduce yourself?

Configure a professional firewall using pfSense

The guide will take you through the setup of the pfSense firewall with one WAN interface, one LAN interface and one Opt1-WiFi Interface.

This guide was written for Linksys, Netgear, and D-link users with no firewall or router experience. No experience is needed with FreeBSD or GNU/Linux to install and run pfSense. When you are finished, management of pfSense will be from a web interface just like any of the SOHO firewall/router appliances.

Book review: Linux Firewalls: Attack Detection and Response with iptables, psad, and fwsnort by Michael Rash

The stability of an enterprise-wide infrastructure depends on understanding innovative, defensive security-related software. Linux Firewalls: Attack Detection and Response with iptables, psad and fwsnort written by Michael Rash and published by No Starch Press, outlines viable approaches that enable a defensive solution in depth.

Introduction to Firestarter

Most modern GNU/Linux distributions are secure with their default minimal installs, whether desktop or server, while some distributions are designed specifically with security in mind. However, any GNU/Linux distribution that needs services available to other users or systems will need either enhanced or configurable security. There are other situations in which added security is beneficial; for example, a large environment, while secure to the outside world, would be enhanced with additional security measures in place.

Interview with Jeff Starkweather, Chris Buechler and Scott Ullrich

Centipede Networks has recently entered a partnership with BSD Perimeter to offer commercial support for two important free software projects, pfSense and m0n0wall. I had a chance to talk to Jeff Starkweather (CEO of Centipede Networks), Chris Buechler (BSD Perimiter’s CTO) and Scott Ullrich (Chief Architect at BSD Perimiter).

TM: Hello everybody, and thank you for answering my questions! Jeff, Chris, Scott please introduce yourselves and your companies to our readers.

Firewall Builder

Have you ever wanted to configure a personal firewall for your GNU/Linux box, but were scared of the complexity of iptables? Well, I might not be able to make you a security expert, but I can show you a tool that will help you to configure your personal firewall the easy way. The secret? Firewall Builder (also known as fwbuilder for short).
