</mediaobject>This is useful when you have a computer (3) which has
Internet (2) access and is connected also to a local network (1). You can
use computer (3) as a gateway to give that access to other workstations
(5) and (6) in the local network (1). For this, the gateway must have
two interfaces; the first one such as an ethernet card must be
connected to the local network, and the second one (4) connected to the
Internet (2).</para>
<para>The first step is to verify that the network and the access to
Internet are set up, as documented in <xref
linkend="draknetcenter"/>.</para>

<title>Gateway wizard</title>
<para>The wizard<footnote>
<para>You can start this tool from the command line, by typing
<emphasis role="bold">drakgw</emphasis> as root.</para>
</footnote> offers successive steps which are shown below:</para>
<para><itemizedlist>
<listitem>
<para>If the wizard does not detect at least two interfaces, it
warns about this and asks to stop the network and configure the
hardware.</para>
</listitem>
<listitem>
<para>specify the interface used for the Internet connection. The
wizard automatically suggests one of the interfaces, but you should
verify that what is proposed is correct.</para>
</listitem>
<listitem>
<para>specify which interface is used for the Lan access. The wizard
also proposes one, check that this is correct.</para>
</listitem>
<listitem>
<para>The wizard proposes parameters for the Lan network, such as IP
address, mask and domain name. Check that these parameters are
compatible with the actual configuration. It is recommended that you
accept these values.</para>
</listitem>
<listitem>
<para>specify if the computer has to be used as a DNS server. If yes,
the wizard will check that <code>bind</code> is installed.
Otherwise, you have to specify the address of a DNS server.</para>
</listitem>
<listitem>
<para>specify if the computer is to be used as a DHCP server. If yes,
the wizard will check that <code>dhcp-server</code> is installed and
offer to configure it, with start and end addresses in the DHCP
range.</para>
</listitem>
<listitem>
<para>specify if the computer is to be used as a proxy server. If
yes, the wizard will check that <code>squid</code> is installed and
offer to configure it, with the address of the administrator
(admin@mydomain.com), name of the proxy (myfirewall@mydomaincom),
the port (3128) and the cache size (100 Mb).</para>
</listitem>
<listitem>
<para>The last step allows you to check if the gateway machine is
connected to printers and to share them.</para>
</listitem>
</itemizedlist></para>
<para>You will be warned about the need to check the firewall if it is
active.</para>
</section>
<section xml:id="drakgw-configure">
<title>Configure the client</title>
<para>If you have configured the gateway machine with DHCP, you only need
to specify in the network configuration tool that you get an address
automatically (using DHCP). The parameters will be obtained when
connecting to the network. This method is valid whatever operating
system the client is using.</para>
<para>If you must manually specify the network parameters, you must in
particular specify the gateway by entering the IP-address of the machine
acting as the gateway.</para>
</section>
<section xml:id="drakgw-stop">
<title>Stop connection sharing</title>
<para>If you want to stop sharing the connection on the Mageia computer,
launch the tool. It will offer to reconfigure the connection or to stop
the sharing.</para>
