+    <title>Shorewall 5.0.5 and Earlier</title>
+
+    <para>Both Docker and Shorewall assume that they 'own' the iptables
+    configuration. This leads to problems when Shorewall is restarted or
+    reloaded, because it drops all of the rules added by Docker. Fortunately,
+    the extensibility features in Shorewall allow users to <ulink
+    url="https://blog.discourse.org/2015/11/shorewalldocker-two-great-tastes-that-taste-great-together/#">create
+    their own solution</ulink> for saving the Docker-generated rules before
+    these operations and restoring them afterwards.</para>
+  </section>
+
+  <section>
+    <title>Shorewall 5.0.6 and Later</title>
+
+    <para>Beginning with Shorewall 5.0.6, Shorewall has native support for
+    simple Docker configurations. This support is enabled by setting
+    DOCKER=Yes in shorewall.conf. With this setting, the generated script
+    saves the Docker-created ruleset before executing a
+    <command>stop</command>, <command>start</command>,
+    <command>restart</command> or <command>reload</command> operation and
+    restores those rules along with the Shorewall-generated ruleset.</para>
+
+    <para>This support assumes that the default Docker bridge (docker0) is
+    being used. It is recommended that this bridge be defined to Shorewall in
+    <ulink
+    url="manpages/shorewall-interfaces.html">shorewall-interfaces(8)</ulink>.
+    As shown below, you can control inter-container communication using the
+    <option>bridge</option> and <option>routeback</option> options. If docker0
+    is not defined to Shorewall, then Shorewall will save and restore the
+    FORWARD chain rules involving that interface.</para>
