  <section>
    <title>IPSEC</title>

    <para>The 2.6 Linux kernel introduces a new implementation of IPSEC which
    eliminates the <filename class="devicefile">ipsecN</filename> device
    names. Netfilter/iptables support for this new implementation is
    incomplete and therefore Shorewall support is limited. See the <ulink
    url="IPSEC.htm">Shorewall IPSEC documentation</ulink>.</para>
