    <title>Description</title>

    <para>This file is used to define the MAC addresses and optionally their
    associated IP addresses to be allowed to use the specified interface. The
    feature is enabled by using the <emphasis role="bold">maclist</emphasis>
    option in the <ulink
    url="shorewall-interfaces.html">shorewall-interfaces</ulink>(5) or <ulink
    url="shorewall-hosts.html">shorewall-hosts</ulink>(5) configuration
    file.</para>

    <para>The columns in the file are as follows.</para>

        role="bold">ACCEPT</emphasis>|<emphasis

        <listitem>
          <para><emphasis role="bold">ACCEPT</emphasis> or <emphasis
          role="bold">DROP</emphasis> (if MACLIST_TABLE=filter in <ulink
          url="shorewall.conf.html">shorewall.conf</ulink>(5), then REJECT is
          also allowed). If specified, the
          <replaceable>log-level</replaceable> causes packets matching the
          rule to be logged at that level.</para>

          <para>MAC <emphasis>address</emphasis> of the host -- you do not
          need to use the Shorewall format for MAC addresses here. If
          <emphasis role="bold">IP ADDRESSESES</emphasis> is supplied then
          <emphasis role="bold">MAC</emphasis> can be supplied as a dash
          (<emphasis role="bold">-</emphasis>)</para>

        role="bold">,</emphasis><emphasis>address</emphasis>]...]</term>

        <listitem>
          <para>If specified, both the MAC and IP address must match. This
          column can contain a comma-separated list of host and/or subnet
          addresses. If your kernel and iptables have iprange match support
          then IP address ranges are also allowed. Similarly, if your kernel
          and iptables include ipset support than set names (prefixed by "+")
          are also allowed.</para>
