  <section>
    <title>Falling Back to the Previous Version of Shorewall using the
    Fallback Script</title>

    <para>If you install Shorewall and discover that it doesn't work for you,
    you can fall back to your previously installed version. To do that:</para>

    <itemizedlist>
      <listitem>
        <para>cd to the distribution directory for the version of Seattle
        Firewall that you are currently running (NOT the version that you want
        to fall back to).</para>
      </listitem>

      <listitem>
        <para>Type <quote>./fallback.sh</quote></para>
      </listitem>
    </itemizedlist>

    <caution>
      <para>The fallback script will replace /etc/shorewall/policy,
      /etc/shorewall/rules, /etc/shorewall/interfaces, /etc/shorewall/nat,
      /etc/shorewall/proxyarp and /etc/shorewall/masq with the version of
      these files from before the current version was installed. Any changes
      to any of these files will be lost.</para>
    </caution>
  </section>

  <section>
    <title>Falling Back to the Previous Version of Shorewall using rpm</title>

    <para>If your previous version of Shorewall was installed using RPM, you
    may fall back to that version by typing <quote>rpm -Uvh --force &lt;old
    rpm&gt;</quote> at a root shell prompt (Example: <quote>rpm -Uvh --force
    /downloads/shorewall-3.1.1-0.noarch.rpm</quote> would fall back to the
    3.1.1-0 version of Shorewall).</para>
  </section>

  <section>
    <title>Uninstalling Shorewall</title>

    <para>If you no longer wish to use Shorewall, you may remove it by:</para>

    <itemizedlist>
      <listitem>
        <para>cd to the distribution directory for the version of Shorewall
        that you have installed.</para>
      </listitem>

      <listitem>
        <para>type <quote>./uninstall.sh</quote></para>
      </listitem>
    </itemizedlist>

    <para>If you installed using an rpm, at a root shell prompt type
    <quote>rpm -e shorewall</quote>.</para>
