The GUI screen to control the firewall is available from the menu (System > Administration >
Firewall) or can be started from the command line using the system-config-firewall command.
Once started, the toolbar provides buttons to allow the firewall to be enabled/disabled(B). You can
also configure basic trusted services, such as SSH, FTP and HTTP(C), by putting a tick in the
