<title>Description</title>
<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>
<para>For information about set lists and exclusion, see <ulink
url="shorewall-exclusion.html">shorewall-exclusion</ulink> (5).</para>
<para>Beginning with Shorewall 4.5.16, you can increment one or more
nfacct objects each time a packet matches an ipset. You do that by listing
the objects separated by commas within parentheses.</para>
<para>Example:</para>
<simplelist>
<member>+myset[src](myobject)</member>
</simplelist>
<para>In that example, when the source address of a packet matches the
<emphasis role="bold">myset</emphasis> ipset, the <emphasis
role="bold">myobject</emphasis> nfacct counter will be incremented.</para>
