Tools that come with Mandriva, Fedora, and Red Hat Enterprise Linux (RHEL) offer a few ways to
configure a firewall using GUI tools. During installation of Fedora or RHEL, the anaconda installer
offers a screen for selecting your level of firewall protection. Mandriva offers a firewall tool with its
Control Center.
Starting Your Firewall in Fedora
During the first boot process, after installing Fedora or RHEL systems, the Firewall Configuration
screen enables you to put a basic firewall in place. Once Fedora is installed, you can use the Firewall
Configuration Window (select System???Firewall), as shown in Figure 18-1.

The Fedora Firewall Configuration screen handles almost everything the average desktop user
needs in a firewall. Here is what you can do with the settings on that page:
Disable the firewall??”Although this option is not generally recommended, some people
choose Disable firewall if they are directly connected to a router firewall or feel no threat
from their network connection. This allows connection requests through to all ports.
Requests to configured services are allowed, while requests for other services are ignored.
