         <p><a name="firewall-pa1"></a>This section allows you to configure some simple firewall rules: they
            determine which type of message from the Internet will be accepted by the
            target system. This, in turn, allows the corresponding services on the
            system to be accessible from the Internet.
         </p>
         
           
         <p>In the default setting (no button is checked), no service of the system is
            accessible from the network. The <span class="emphasis"><em>Everything (no
                  firewall)</em></span> option enables access to all services of the machine -
            an option that does not make much sense in the context of the installer
            since it would create a totally unprotected system. Its veritable use is in
            the context of the Mageia Control Center (which uses the same GUI layout)
            for temporarily disabling the entire set of firewall rules for testing and
            debugging purposes.
         </p>
         
           
         <p>All other options are more or less self-explanatory. As an example, you will
            enable the CUPS server if you want printers on your machine to be accessible
            from the network.
         </p>

         <p>The <span class="emphasis"><em>Advanced</em></span> option opens a window where you can enable
            a series of services by typing a list of <span class="quote">&#8220;<span class="quote">couples</span>&#8221;</span> (blank
            separated)
