<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 tuple, two alternative syntaxes are
|
|
available:</para>
|
|
|
|
<simplelist>
|
|
<member>[<replaceable>number</replaceable>] - Indicates that 'src' or
|
|
'dst' should be repeated <replaceable>number</replaceable> 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 or SPORT column, the following pairs are
|
|
equivalent:</para>
|
|
|
|
<itemizedlist>
|
|
<listitem>
|
|
<para>+myset[2] and +myset[src,src]</para>
|
|
</listitem>
|
|
</itemizedlist>
|
|
|
|
<para>In a DEST or DPORT column, the following pairs 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>
|
|
|
|
<para>Beginning with Shorewall 4.6.0, an ipset name (and src/dst list, if
|
|
any) can be immediately be followed by a list of match options.</para>
|
|
|
|
<important>
|
|
<para>These additional match options are not available in <ulink
|
|
url="shorewall-tcfilters.html">shorewall-tcfilters(5)</ulink>.</para>
|
|
</important>
|
|
|
|
<para>Available options are:</para>
|
|
|
|
<variablelist>
|
|
<varlistentry>
|
|
<term>nomatch</term>
|
|
|
|
<listitem>
|
|
<para>If the set type supports the nomatch flag, then the matching
|
|
is reversed: a match with an element flagged with nomatch returns
|
|
true, while a match with a plain element returns false. This option
|
|
requires the 'Ipset Match nomatch' capability in your kernel and
|
|
ip[6]tables.</para>
