    <title>Description</title>

    <para>These files specify which kernel modules Shorewall will load before
    trying to determine your iptables/kernel's capabilities.</para>

    <para>The <filename>modules</filename> file is used when
    LOAD_HELPERS_ONLY=No in <ulink
    url="shorewall.conf.html">shorewall.conf</ulink>(8); the
    <filename>helpers</filename> file is used when
    LOAD_HELPERS_ONLY=Yes</para>

    <para>Each record in the files has the following format:</para>

    <cmdsynopsis>
      <command>loadmodule</command>

      <arg choice="plain"><replaceable
      class="parameter">modulename</replaceable></arg>

      <arg rep="repeat"><replaceable>moduleoption</replaceable></arg>
    </cmdsynopsis>

    <para>The <replaceable>modulename</replaceable> names a kernel module
    (without suffix). Shorewall will search for modules based on your
    MODULESDIR and MODULE_SUFFIX settings in <ulink
    url="shorewall.conf.html">shorewall.conf</ulink>(8). The
    <replaceable>moduleoption</replaceable>s are passed to modprobe (if
    installed) or to insmod.</para>

    <para>The /usr/share/shorewall/modules file contains a large number of
    modules. Users are encouraged to copy the file to /etc/shorewall/modules
    and modify the copy to load only the modules required or to use
    LOAD_HELPERS_ONLY=Yes.<note>
        <para>If you build monolithic kernels and have not installed
        module-init-tools, then create an empty /etc/shorewall/modules file;
        that will prevent Shorewall from trying to load modules at all.</para>
      </note></para>
