    <para>This file is used to define the hosts that are accessible when the

                <para>Set up a rule to ACCEPT traffic from these hosts back to

                host to other listed hosts (and the firewall) is allowed. If
                <emphasis role="bold">source</emphasis> is specified then

          if your kernel and iptables include port range support.</para>

          <para>Beginning with Shorewall 4.5.15, you may place '=' in this
          column, provided that the DEST PORT(S) column is non-empty. This
          causes the rule to match when either the source port or the
          destination port in a packet matches one of the ports specified in
          DEST PORTS(S). Use of '=' requires multi-port match in your iptables
          and kernel.</para>

    <note>
      <para>The <emphasis role="bold">source</emphasis> and <emphasis
      role="bold">dest</emphasis> options work best when used in conjunction
      with ADMINISABSENTMINDED=Yes in <ulink
