    <title>Description</title>

    <para>This file was added in Shorewall 4.4.16 and is used to define Proxy
    NDP. There is one entry in this file for each IPv6 address to be
    proxied.</para>

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

    <variablelist>
      <varlistentry>
        <term><emphasis role="bold">ADDRESS</emphasis> -
        <emphasis>address</emphasis></term>

        <listitem>
          <para>IPv6 Address.</para>

      <varlistentry>
        <term><emphasis role="bold">INTERFACE</emphasis> -
        <emphasis>interface</emphasis> (Optional)</term>

        <listitem>
          <para>Local interface where system with the ip address in ADDRESS is
          connected. Only required when the HAVEROUTE column is left empty or
          is set to <emphasis role="bold">no</emphasis> or <emphasis
          role="bold">No</emphasis>.</para>

        <emphasis>interface</emphasis></term>

        <listitem>
          <para>External Interface to be used to access this system from the
          Internet.</para>

        role="bold">-</emphasis>|<emphasis
        role="bold">Yes</emphasis>|<emphasis role="bold">No</emphasis>]</term>

        <listitem>
          <para>If there is already a route from the firewall to the host
          whose address is given, enter <emphasis role="bold">Yes</emphasis>
          or <emphasis role="bold">yes</emphasis> in this column. Otherwise,
          enter <emphasis role="bold">no</emphasis> or <emphasis
          role="bold">No</emphasis> or leave the column empty and Shorewall
          will add the route for you. If Shorewall6 adds the route, its
          persistence depends on the value of the<emphasis
          role="bold">PERSISTENT</emphasis> column contains <emphasis
          role="bold">Yes</emphasis>; otherwise, <emphasis
          role="bold">shorewall6 stop</emphasis> or <emphasis
          role="bold">shorewall clear6</emphasis> will delete the
          route.</para>

        <listitem>
          <para>If HAVEROUTE is <emphasis role="bold">No</emphasis> or
          <emphasis role="bold">no</emphasis>, then the value of this column
          determines if the route added by Shorewall persists after a
          <emphasis role="bold">shorewall6 stop</emphasis> or a <emphasis
          role="bold">shorewall6 clear</emphasis>. If this column contains
          <emphasis role="bold">Yes</emphasis> or <emphasis
          role="bold">yes</emphasis> then the route persists; If the column is
          empty or contains <emphasis role="bold">No</emphasis> or <emphasis
          role="bold">no</emphasis> then the route is deleted by
          <command>shorewall6 stop</command> or <command>shorewall6
