    <title>Description</title>

    <para>This file sets options that apply to Shorewall Lite as a
    whole.</para>

    <para>The file consists of Shell comments (lines beginning with '#'),
    blank lines and assignment statements
    (<emphasis>variable</emphasis>=<emphasis>value</emphasis>). Each
    variable's setting is preceded by comments that describe the variable and
    it's effect.</para>

    <para>Any option not specified in this file gets its value from the
    shorewall.conf file used during compilation of
    /var/lib/shorewall-lite/firewall.</para>

    <title>OPTIONS</title>

    <para>The following options may be set in shorewall.conf.</para>

    <variablelist>
      <varlistentry>
        <term><emphasis
        role="bold">IPTABLES=</emphasis><emphasis>pathname</emphasis></term>

        <listitem>
          <para>This parameter names the iptables executable to be used by
          Shorewall. If not specified or if specified as a null value, then
          the iptables executable located using the PATH option is
          used.</para>
        </listitem>
      </varlistentry>

      <varlistentry>
        <term><emphasis
        role="bold">LOGFILE=</emphasis><emphasis>pathname</emphasis></term>

        <listitem>
          <para>This parameter tells the /sbin/shorewall program where to look
          for Shorewall messages when processing the <emphasis
          role="bold">dump</emphasis>, <emphasis
          role="bold">logwatch</emphasis>, <emphasis role="bold">show
          log</emphasis>, and <emphasis role="bold">hits</emphasis> commands.
          If not assigned or if assigned an empty value, /var/log/messages is
          assumed.</para>
        </listitem>
      </varlistentry>

      <varlistentry>
        <term><emphasis
        role="bold">LOGFORMAT="</emphasis><emphasis>formatstring</emphasis><emphasis
        role="bold">"</emphasis></term>

        <listitem>
          <para>The value of this variable generate the --log-prefix setting
          for Shorewall logging rules. It contains a “printf” formatting
          template which accepts three arguments (the chain name, logging rule
          number (optional) and the disposition). To use LOGFORMAT with
          fireparse, set it as:</para>

          <programlisting>    LOGFORMAT="fp=%s:%d a=%s "</programlisting>

          <para>If the LOGFORMAT value contains the substring “%d” then the
          logging rule number is calculated and formatted in that position; if
          that substring is not included then the rule number is not included.
          If not supplied or supplied as empty (LOGFORMAT="") then
          “Shorewall:%s:%s:” is assumed.</para>
        </listitem>
      </varlistentry>

      <varlistentry>
        <term>PATH=<emphasis role="bold">pathname</emphasis>[<emphasis
        role="bold">:</emphasis><emphasis>pathname</emphasis>]...</term>

        <listitem>
          <para>Determines the order in which Shorewall searches directories
          for executable files.</para>
        </listitem>
      </varlistentry>

      <varlistentry>
        <term><emphasis
        role="bold">RESTOREFILE=</emphasis><emphasis>filename</emphasis></term>

        <listitem>
          <para>Specifies the simple name of a file in /var/lib/shorewall to
          be used as the default restore script in the <emphasis
          role="bold">shorewall save</emphasis>, <emphasis
          role="bold">shorewall restore</emphasis>, <emphasis
          role="bold">shorewall forget </emphasis>and <emphasis

      <varlistentry>
        <term><emphasis
        role="bold">SHOREWALL_SHELL=</emphasis><emphasis>pathname</emphasis></term>

        <listitem>
          <para>This option is used to specify the shell program to be used to
          run the Shorewall compiler and to interpret the compiled script. If
          not specified or specified as a null value, /bin/sh is assumed.
          Using a light-weight shell such as ash or dash can significantly
          improve performance.</para>
        </listitem>
      </varlistentry>

      <varlistentry>
        <term><emphasis
        role="bold">SUBSYSLOCK=</emphasis><emphasis>pathname</emphasis></term>

        <listitem>
          <para>This parameter should be set to the name of a file that the
          firewall should create if it starts successfully and remove when it
          stops. Creating and removing this file allows Shorewall to work with
          your distribution's initscripts. For RedHat, this should be set to
          /var/lock/subsys/shorewall. For Debian, the value is
          /var/state/shorewall and in LEAF it is /var/run/shorwall.</para>
        </listitem>
      </varlistentry>

      <varlistentry>
        <term><emphasis
        role="bold">VERBOSITY=</emphasis><emphasis>number</emphasis></term>

        <listitem>
          <para>Shorewall has traditionally been very noisy (produced lots of
          output). You may set the default level of verbosity using the
          VERBOSITY OPTION.</para>

          <para>Values are:</para>

          <simplelist>
            <member>0 — Silent. You may make it more verbose using the -v
            option</member>

            <member>1 — Major progress messages displayed</member>

            <member>2 — All progress messages displayed (old default
            behavior)</member>
          </simplelist>

          <para>If not specified, then 2 is assumed.</para>
