<title>Description</title>
|
|
|
|
<para>The /etc/shorewall/zones file declares your network zones. You
|
|
specify the hosts in each zone through entries in
|
|
<filename>/etc/shorewall/interfaces</filename> or
|
|
<filename>/etc/shorewall/hosts</filename>.</para>
|
|
|
|
<warning>
|
|
<para>The format of this file changed in Shorewall 3.0.0. You can
|
|
continue to use your old records provided that you set IPSECFILE=ipsec
|
|
in /etc/shorewall/shorewall.conf. This will signal Shorewall that the
|
|
IPSEC-related zone options are still specified in /etc/shorewall/ipsec
|
|
rather than in this file.</para>
|
|
|
|
<para>To use records in the format described below, you must have
|
|
IPSECFILE=zones specified in
|
|
<filename>/etc/shorewall/shorewall.conf</filename> AND YOU MUST NOT SET
|
|
THE 'FW' VARIABLE IN THAT FILE.</para>
|
|
</warning>
|
|
|
|
<para>The columns in the file are as follows.</para>
|
|
|
|
<variablelist>
|
|
<varlistentry>
|
|
<term><emphasis role="bold">ZONE</emphasis></term>
|
|
|
|
<listitem>
|
|
<para>Short name of the zone. The names "all" and "none" are
|
|
reserved and may not be used as zone names. The maximum length of a
|
|
zone name is determined by the setting of the LOGFORMAT option in
|
|
shorewall.conf. With the default LOGFORMAT, zone names can be at
|
|
most 5 characters long.</para>
|
|
|
|
<para>Where a zone is nested in one or more other zones, you may
|
|
follow the (sub)zone name by ":" and a comma-separated list of the
|
|
parent zones. The parent zones must have been defined in earlier
|
|
records in this file.</para>
|
|
|
|
<para>Example:</para>
|
|
|
|
<programlisting>#ZONE TYPE OPTIONS IN OPTIONS OUT OPTIONS
|
|
a ipv4
|
|
b ipv4
|
|
c:a,b ipv4</programlisting>
|
|
|
|
<para>Currently, Shorewall uses this information to reorder the zone
|
|
list so that parent zones appear after their subzones in the list.
|
|
The IMPLICIT_CONTINUE option in shorewall.conf can also create
|
|
implicit CONTINUE policies to/from the subzone.</para>
|
|
|
|
<para>In the future, Shorewall may make additional use of nesting
|
|
information.</para>
