<title>Description</title>
<para>The shorewall utility is used to control the Shoreline Firewall
(Shorewall).</para>
</refsect1>
<refsect1>
<title>Options</title>
<para>The <option>trace</option> and <option>debug</option> options are
used for debugging. See <ulink
url="/starting_and_stopping_shorewall.htm#Trace">http://www.shorewall.net/starting_and_stopping_shorewall.htm#Trace</ulink>.</para>
<para>The <option>nolock</option> option prevents the command from
attempting to acquire the Shorewall lockfile. It is useful if you need to
include <command>shorewall</command> commands in
<filename>/etc/shorewall/started</filename>.</para>
<para>The <emphasis>options</emphasis> control the amount of output that
the command produces. They consist of a sequence of the letters <emphasis
role="bold">v</emphasis> and <emphasis role="bold">q</emphasis>. If the
options are omitted, the amount of output is determined by the setting of
the VERBOSITY parameter in <ulink
url="/manpages/shorewall.conf.html">shorewall.conf</ulink>(5). Each
<emphasis role="bold">v</emphasis> adds one to the effective verbosity and
each <emphasis role="bold">q</emphasis> subtracts one from the effective
VERBOSITY. Alternatively, <emphasis role="bold">v</emphasis> may be
followed immediately with one of -1,0,1,2 to specify a specify VERBOSITY.
There may be no white-space between <emphasis role="bold">v</emphasis> and
the VERBOSITY.</para>
<para>The <emphasis>options</emphasis> may also include the letter
<option>t</option> which causes all progress messages to be
timestamped.</para>
</refsect1>

<title>Commands</title>
<para>The available commands are listed below.</para>
<variablelist>
<varlistentry>

<replaceable>interface</replaceable>[:<replaceable>host-list</replaceable>]...
<replaceable>zone</replaceable> | <replaceable>zone</replaceable>
<replaceable>host-list</replaceable> }</term>
<listitem>
<para>Adds a list of hosts or subnets to a dynamic zone usually used
with VPN's.</para>
<para>The <emphasis>interface</emphasis> argument names an interface
defined in the <ulink
url="/manpages/shorewall-interfaces.html">shorewall-interfaces</ulink>(5)
file. A <emphasis>host-list</emphasis> is comma-separated list whose

<para>Start shorewall. Existing connections through shorewall
managed interfaces are untouched. New connections will be allowed
only if they are allowed by the firewall rules or policies. If a
<replaceable>directory</replaceable> is included in the command,
Shorewall will look in that <emphasis>directory</emphasis> first for
configuration files. If <emphasis role="bold">-f</emphasis> is
specified, the saved configuration specified by the RESTOREFILE
option in <ulink
url="/manpages/shorewall.conf.html">shorewall.conf</ulink>(5) will
be restored if that saved configuration exists and has been modified
more recently than the files in /etc/shorewall. When <emphasis
role="bold">-f</emphasis> is given, a
<replaceable>directory</replaceable> may not be specified.</para>
<para>Update: In Shorewall 4.4.20, a new LEGACY_FASTSTART option was
added to <ulink
url="/manpages/shorewall.conf.html">shorewall.conf</ulink>(5). When
LEGACY_FASTSTART=No, the modification times of files in
/etc/shorewall are compared with that of /var/lib/shorewall/firewall
(the compiled script that last started/restarted the
firewall).</para>
<para>The <option>-n</option> option causes Shorewall to avoid
updating the routing table(s).</para>
<para>The <option>-p</option> option causes the connection tracking
table to be flushed; the <command>conntrack</command> utility must
be installed to use this option.</para>
<para>The <option>-c</option> option was added in Shorewall 4.4.20
and performs the compilation step unconditionally, overriding the
AUTOMAKE setting in <ulink
url="/manpages/shorewall.conf.html">shorewall.conf</ulink>(5). When
both <option>-f</option> and <option>-c</option>are present, the
result is determined by the option that appears last.</para>
<para>The <option>-T</option> option was added in Shorewall 4.5.3
and causes a Perl stack trace to be included with each
compiler-generated error and warning message.</para>
<para>The -i option was added in Shorewall 4.6.0 and causes a
warning message to be issued if the current line contains
alternative input specifications following a semicolon (";"). Such
lines will be handled incorrectly if INLINE_MATCHES is set to Yes in
<ulink
url="/manpages/shorewall.conf.html">shorewall.conf(5)</ulink>.</para>
<para>The <option>-C</option> option was added in Shorewall 4.6.5
and is only meaningful when the <option>-f</option> option is also
specified. If the previously-saved configuration is restored, and if
the <option>-C</option> option was also specified in the <emphasis

counters will be restored.</para>

<para>If Shorewall is started then the firewall state is saved to a
temporary saved configuration
(<filename>/var/lib/shorewall/.try</filename>). Next, if Shorewall
is currently started then a <emphasis role="bold">restart</emphasis>
command is issued using the specified configuration
<replaceable>directory</replaceable>; otherwise, a <emphasis
role="bold">start</emphasis> command is performed using the
specified configuration <replaceable>directory</replaceable>. if an
error occurs during the compilation phase of the <emphasis
role="bold">restart</emphasis> or <emphasis
role="bold">start</emphasis>, the command terminates without
changing the Shorewall state. If an error occurs during the
<emphasis role="bold">restart</emphasis> phase, then a <emphasis
role="bold">shorewall restore</emphasis> is performed using the
saved configuration. If an error occurs during the <emphasis
role="bold">start</emphasis> phase, then Shorewall is cleared. If
the <emphasis role="bold">start</emphasis>/<emphasis
role="bold">restart</emphasis> succeeds and a
<replaceable>timeout</replaceable> is specified then a <emphasis

<replaceable>timeout</replaceable> seconds.</para>
<para>Beginning with Shorewall 4.5.0, the numeric
<replaceable>timeout</replaceable> may optionally be followed by an
<option>s</option>, <option>m</option> or <option>h</option> suffix
