More general host options include turning on kernel antispoofing support, whether source routing should be ignored, and how to treat various ICMP packets. In the host settings you will find options to set the paths of specific tools on the machine, override various TCP settings such as the FIN and keep-alive timeouts, as well as turn on Explicit Congestion Notification ( ECN), timestamps, and SYN cookies. When you click on the firewall itself in the left tree or any cell in the grid showing the firewall policy in the top of the window, you can edit both the host and firewall settings. This is easy to work around by renaming your user catalog SSH service definition. That means that if you drag your user SSH service into the service cell, you will see two SSH entries in that cell and have no indication that one is your personal catalog version while the other is the standard (system) catalog version. Although this all works well, one user interface issue here is that both the definition in the standard (system) catalog and your user catalog for the SSH service have the same name. To use your version of the SSH service definition, you can drag and drop it from the left tree view into the service cell of a rule for your firewall.

When you have your own copy of the SSH service port definition you are free to edit it. The drop-down list just above the tree view on the left lets you select either the standard (system) or user catalog. If you are running SSH on a custom port, you can either edit the system catalog for SSH or right-click it in the left tree view in the standard (system) catalog and select “Duplicate/Place in library User” to create a personal copy of the service. The service that the template refers to is part of the system definitions and is read-only, allowing you to see the details in the pane but not edit them. Instead of simply entering a TCP connection type and a port number, the template firewall offers the SSH service as an option in the tree view on the left side, which is what this rule is using to define where the connection is destined. As you click on each cell in the grid in the top of the window, the bottom pane changes to allow you to edit the data in that cell. The firewall rules for Template 1 are shown in the screenshot below. The web server template allows HTTP and SSH traffic for the server that is running the firewall. The linksys firewall template is designed specifically to run on Linksys routers, while the c36xx is an example for Cisco routers.

While the policy for this sort of firewall is simple, having it in the list allows laptop users to install a firewall quickly. The fourth item on the list, host fw template 1, simply protects a single host, only allowing incoming SSH access. Template 3 is designed for setting up a demilitarized zone ( DMZ) subnet by having three network interfaces on the server - one facing the Internet with a static IP address, a local private subnet, and a DMZ subnet that is accessible from the Internet. Template 2 is similar to template 1 but is designed for the server to be a DHCP server for your local network. Template 1, shown in the screenshot, supports a dynamic IP address assigned by your ISP and a local fixed private subnet on a second network interface of the server. Because fwbuilder has a selection of firewalls that are identical or close to what many users will want to use, it makes getting started much simpler. If you choose to enable firewall templates and create an iptables firewall, you will see the dialog window shown. By right-clicking on the Firewalls item in the tree view you can create a new firewall. When you start fwbuilder, you’ll see the window shown behind the new firewall dialog in the screenshot below. WARNING: icns.path is not defined: install target not created
Running qmake: /usr/lib64/qt-3.3/bin/qmake I found the below warning during configuration if you get it, you can ignore it. configure make sudo make install procedure. Install the two packages using the normal. fwbuilder is shipped as two tarballs: libfwbuilder and fwbuilder. In this article I’ll build from source on a 64-bit Fedora 9 machine using fwbuilder version 2.1.19. fwbuilder is packaged as a 1-Click install for openSUSE 10.3, but not for version 11 as yet. Packages for fwbuilder are available in the Ubuntu Hardy and Fedora 9 repositories. Separating the actual policy you define and the implementation in this way should let you change what hardware is running your firewall without having to redefine your policy for that platform. It can compile the filtering policy you define into many specifications, including iptables and various languages used by Cisco and Linksys routers. Firewall Builder (fwbuilder) is a graphical application that can help you to configure IP traffic filtering.
