    <para>This file is used to define the hosts that are accessible when the
    firewall is stopped or is being stopped.</para>

    <warning>
      <para>Changes to this file do not take effect until after the next
      <command>shorewall start</command> or <command>shorewall
      restart</command> command.</para>

          <para>A comma-separated list of options. The order of the options is

                <para>Set up a rule to ACCEPT traffic from these hosts back to
                themselves. Beginning with Shorewall 4.4.9, this option is
                automatically set if <emphasis
