  <para>Unpack the <filename>128T/128t-cloud-init-example.tar.gz</filename>
  archive and check the README file for more details:</para>

  <programlisting>&gt;tar -zxf 128t-cloud-init-example.tar.gz
&gt;cd 128T/cloud-init-example/
&gt;ls ./

  <para>To generate the cloud-init iso image:</para>

  <programlisting>&gt;genisoimage -output centos_128t_ci.iso -volid cidata -joliet \
-rock user-data meta-data t128-running.xml </programlisting>

      <listitem>
        <para><literal>user-data</literal> and <literal>meta-data</literal>
        files must be kept unchanged.</para>
      </listitem>

      <listitem>
        <para>To update the 128T configuration change the

      <listitem>
        <para>XML is the same file downloaded from 128T web access:
        <literal>configuration -&gt; Import and Export Configuration -&gt;
        Export Configuration -&gt; Download Configuration</literal>. The
        configuration can be updated from a web interface, downloaded onto the
        development host and used in generating a new cloud-init iso
        image.</para>
      </listitem>
    </itemizedlist></para>

  <para>By default, <literal>t128-running.xml</literal> is configured to pass
  all traffic from the LAN to the WAN interface. There is only one change
  required for the 128T VNF to work on the user's network:</para>

  <programlisting>&lt;rt:next-hop&gt;172.24.15.254&lt;/rt:next-hop&gt;</programlisting>

  <para>Please change &lt;172.24.15.254&gt; with the IP address of your
  Gateway in the <filename>t128-running.xml</filename> file and generate a new
  iso image as described above. For more details about configuring the 128T
  VNF please contact 128 Technologies.</para>
