    <title>Description</title>

    <para>This file is used to define the hosts that are accessible when the
    firewall is stopped or is being stopped.</para>

    <warning>
      <para>Changes to this file do not take effect until after the next
      <command>shorewall start</command>, <command>shorewall reload</command>,
      <command>shorewall restart</command>, or <option>shorewall
      compile</option> command.</para>
    </warning>

    <para>The columns in the file are as follows (where the column name is
    followed by a different name in parentheses, the different name is used in
    the alternate specification syntax).</para>

      <varlistentry>
        <term><emphasis role="bold">ACTION</emphasis> -
        <option>ACCEPT|NOTRACK|DROP</option></term>

        <listitem>
          <para>Determines the disposition of the packet.</para>

          <para><option>ACCEPT</option> means that the packet will be
          accepted.</para>

          <para><option>NOTRACK</option> indicates that no conntrack entry
          should be created for the packet. <option>NOTRACK</option> does not
          imply <option>ACCEPT</option>.</para>

          <para><option>DROP</option> was added in Shorewall 4.6.0 and causes
          the packet to be dropped in the raw table's PREROUTING chain.</para>

        <listitem>
          <para><option>$FW</option> matches packets originating on the
          firewall itself, while <replaceable>interface</replaceable>
          specifies packets arriving on the named interface.</para>

          <para>This column may also include a comma-separated list of
          IP/subnet addresses. If your kernel and iptables include iprange
          match support, IP address ranges are also allowed. Ipsets and
          exclusion are also supported. When <option>$FW</option> or interface
          are specified, the list must be preceded by a colon (":").</para>

        <listitem>
          <para><option>$FW</option> matches packets addressed the firewall
          itself, while <replaceable>interface</replaceable> specifies packets
          arriving on the named interface. Neither may be specified if the
          target is <option>NOTRACK</option> or <option>DROP</option>.</para>

          <para>This column may also include a comma-separated list of
          IP/subnet addresses. If your kernel and iptables include iprange

        <listitem>
          <para>Protocol.</para>

          <para>Beginning with Shorewall 4.5.12, this column can accept a
          comma-separated list of protocols.</para>

        <listitem>
          <para>Optional. A comma-separated list of port numbers and/or
          service names from <filename>/etc/services</filename>. May also
          include port ranges of the form
          <replaceable>low-port</replaceable>:<replaceable>high-port</replaceable>
          if your kernel and iptables include port range support.</para>

          <para>This column was formerly labelled DEST PORT(S).</para>

      <varlistentry>
        <term><emphasis role="bold">SPORT</emphasis> ‒
        <replaceable>service-name/port-number-list</replaceable></term>

        <listitem>
          <para>Optional. A comma-separated list of port numbers and/or
          service names from <filename>/etc/services</filename>. May also
          include port ranges of the form
          <replaceable>low-port</replaceable>:<replaceable>high-port</replaceable>
          if your kernel and iptables include port range support.</para>

          <para>Beginning with Shorewall 4.5.15, you may place '=' in this
          column, provided that the DPORT column is non-empty. This causes the
          rule to match when either the source port or the destination port in
          a packet matches one of the ports specified in DEST PORTS(S). Use of
          '=' requires multi-port match in your iptables and kernel.</para>

          <para>This column was formerly labelled SOURCE PORT(S).</para>
