    <para>Note: In the above syntax descriptions, the square brackets ("[]")
    are to be taken literally rather than as meta-characters.</para>

    <para>In most places where a network address may be entered, an ipset may
    be substituted. Set names must be prefixed by the character "+", must
    start with a letter and may be composed of alphanumeric characters, "-"
    and "_".</para>

    <para>Whether the set is matched against the packet source or destination
    is determined by which column the set name appears (SOURCE or DEST). For
    those set types that specify a tupple, two alternative syntaxes are
    available:</para>

    <simplelist>
      <member>[<replaceable>number</replaceable>] - Indicates that 'src' or
      'dst' should repleated number times. Example: myset[2].</member>

      <member>[<replaceable>flag</replaceable>,...] where
      <replaceable>flag</replaceable> is <option>src</option> or
      <option>dst</option>. Example: myset[src,dst].</member>
    </simplelist>

    <para>In a SOURCE column, the following pairs are equivalent:</para>

    <itemizedlist>
      <listitem>
        <para>+myset[2] and +myset[src,src]</para>
      </listitem>
    </itemizedlist>

    <para>In a DEST column, the following paris are equivalent:</para>

    <itemizedlist>
      <listitem>
        <para>+myset[2] and +myset[dst,dst]</para>
      </listitem>
    </itemizedlist>

    <para>Beginning with Shorewall 4.4.14, multiple source or destination
    matches may be specified by enclosing the set names within +[...]. The set
    names need not be prefixed with '+'. When such a list of sets is
    specified, matching packets must match all of the listed sets.</para>

    url="shorewall-exclusion.html">shorewall-exclusion</ulink> (5).</para>
