Once complete, click the Finish button and the template will be loaded into the main screen (see Figure 4). Should the device use a static address, then the address for the network interface would need to be entered. The desktop machine uses DHCP for network addressing, so nothing really needs to be changed in the screen shown in Figure 3. In my example, I am creating a firewall for a single interface host which happens to be a desktop machine. In this example, a single interface template has been chosen. Since each pre-configured template offers different hardware configurations (such as a single external interface, versus a single external and single internal interface) the screen displayed will depend upon which firewall template is selected. Make sure to read the description of the templates, otherwise the wrong template could be chosen resulting in a non-functional firewall.įinally, in the last screen of the wizard (see Figure 4), the network interfaces are named. After this option is chosen, the templates will be presented in the next screen (see Figure 3). The first screen in the wizard is where the option for pre-configured templates is chosen. Most all Linux users will select this option.Īs I mentioned earlier, for this test firewall, the pre-configured firewall templates will be used. The name for the firewall can be any user-specified name required to indicate the purpose the firewall serves.įor those unfamiliar with “Linux 2.4/2.6”, that refers to the kernel release being used on the system. For our example the configurations will be:

The first step in the wizard (see Figure 2) is to give the firewall a name, choose the software running the firewall, and select the operating system running the firewall. Select from pre-configured firewall templates (I highly recommend this be selected.)īased on the template chosen, specific information for the ethernet interface will be required. Software the firewall is based on (such as iptables). Because I recommend first-time users select from the pre-configured templates, the wizard will require the following: When the Create New Firewall button is clicked, a wizard will appear to help create the new firewall. Let’s begin the process of creating a new firewall, based on pre-configured templates, with fwbuilder. But before objects and services can be added, a new firewall must be created. This navigation tree contains everything necessary to create a firewall. In the same window there is an navigation tree (left pane). From that same pane (in the main fwbuilder window) a new firewall can be created or an existing firewall can be imported. From the main window, I recommend all new users click the Watch “Getting Started” tutorial button, which will open up a browser instance to a short, informative video. When fwbuilder is fired up, the main window will appear (see Figure 1). Ultimately, the easiest way to start fwbuilder is by using the desktop menu (as shown above). I actually recommend you running fwbuilder without admin privileges (it is not required), so the security of the system is not comprimised. Why the difference? The former command runs fwbuilder with administrator privileges, the latter wthout. You can start fwbuilder from the command line using sudo fwbuilder or just fwbuilder. In order to start up fwbuilder administrative privileges will be necessary. Once installed, Fwbuilder can be started by clicking System > Administration > Firewall Builder.

Install fwbuilder with the command sudo apt-get install fwbuilder. Install the fwbuilder libraries with the command sudo apt-get install libfwbuilder. Install the GPG key with the command apt-key add PACKAGE-GPG-KEY-fwbuilder.asc. Open /etc/apt/sources.list in a text editor.Īdd deb maverick contrib to the bottom of that file.ĭownload the GPG key with the command wget. In order to get a working, updated Fwbuilder installed on Ubuntu, follow these steps (You will either have to su to the root user or use sudo for this to work): However, if you’re installing Fwbuilder on Ubuntu, the package that will install is out of date and will not work. Installation of Fwbuilder is as simple as searching for “fwbuilder” (no quotes) in your Add/Remove Software tool (such as Package-Kit, Synaptic, etc) and marking Fwbuilder for installation. Let’s take a look at using Fwbuilder on Linux, which might just become a life-long affair with a powerful security system. Fwbuilder supports a wide range of firewalls (Cisco ASA/PIX, Linux iptables, FreeBSD’s ipfilter, OpenBSD’s pf, and more), so its rules can be deployed on multiple platforms.

Fwbuilder is a unique graphical firewall tool that allows the user to create objects and then drag and drop those objects into firewalls, to build a powerful security system for a single PC or a network of PCs.
