-    <title>IPCOMP and IPSEC</title>
-
-    <para>IPSEC can be configured to perform data compression. This is
-    accomplished by compressing the original IP packet, then encapsulating it
-    in an ipcomp (protocol 108) packet. That packet is then encrypted and
-    encapsulated within an ESP packet. Because of the extra protocol header
-    required for compression, short IP packets (such as default ping packets)
-    are not compressed. The Linux IP stack handles these uncompressed packets
-    by creating an IPIP (protocol 4) SA. As a consequence, IPIP packets from
-    the remote gateway must be handled in Shorewall. The easiest way to
-    accomplish this is to add an ACCEPT rule for protocol 4 from the IPSEC vpn
-    zone to the $FW zone:</para>
-
-    <blockquote>
-      <programlisting>#ACTION         SOURCE         DEST       PROTO       DPORT ...
-ACCEPT          vpn            $FW        4</programlisting>
-    </blockquote>
-
-    <para>Note that the source IP address is these IPIP packets is that of the
-    remote peer, so the definition of the ipsec zone in <ulink
-    url="manpages/shorewall-hosts.html">shorewall-hosts</ulink>(5) must
-    include the peer.</para>
-
-    <para>Finally, when IPCOMP is used, it is recommended that the OPTIONS
-    column of the ipsec zone's entry in <ulink
-    url="manpages/shorewall-zones.html">shorewall-zones</ulink>(5) be left
-    empty.</para>
