  <para>Beginning with Shorewall version 1.4.8, Shorewall can interface to
  ftwall. <emphasis role="bold">ftwall</emphasis> is part of the <ulink
  url="http://p2pwall.sourceforge.net">p2pwall project</ulink> and is a
  user-space filter for applications based on the &#34;Fast Track&#34; peer to
  peer protocol. Applications using this protocol include Kazaa, KazaaLite,
  iMash and Grokster.</para>

  <para>To filter traffic from your &#39;loc&#39; zone with ftwall, you insert
  the following rules <emphasis role="bold">near the top</emphasis> of your
  /etc/shorewall/rules file (before and ACCEPT rules whose source is the
  &#39;loc&#39; zone).</para>

  <programlisting>        QUEUE   loc        net        tcp
        QUEUE   loc        net        udp
        QUEUE   loc        fw         udp</programlisting>

  <para>Now simply configure ftwall as described in the ftwall documentation
  and restart Shorewall.</para>
