    <para>The columns in the file are as follows.</para>

        <listitem>
          <para>If there is already a route from the firewall to the host
          whose address is given, enter <emphasis role="bold">Yes</emphasis>
          or <emphasis role="bold">yes</emphasis> in this column. Otherwise,
          enter <emphasis role="bold">no</emphasis> or <emphasis
          role="bold">No</emphasis> or leave the column empty and Shorewall
          will add the route for you. If Shorewall adds the route,the route
          will be persistent if the <emphasis
          role="bold">PERSISTENT</emphasis> column contains <emphasis
          role="bold">Yes</emphasis>; otherwise, <emphasis
          role="bold">shorewall stop</emphasis> or <emphasis

        <listitem>
          <para>If HAVEROUTE is <emphasis role="bold">No</emphasis> or
          <emphasis role="bold">no</emphasis>, then the value of this column
          determines if the route added by Shorewall persists after a
          <emphasis role="bold">shorewall stop</emphasis> or a <emphasis
          role="bold">shorewall clear</emphasis>. If this column contains
          <emphasis role="bold">Yes</emphasis> or <emphasis
          role="bold">yes</emphasis> then the route persists; If the column is
          empty or contains <emphasis role="bold">No</emphasis> or <emphasis
          role="bold">no</emphasis> then the route is deleted at
          <command>shorewall stop</command> or <command>shorewall
