<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
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>
<variablelist>
<varlistentry>
<term><emphasis role="bold">ACTION</emphasis> -
<option>ACCEPT|NOTRACK</option></term>
<listitem>
<para>Determines the disposition of the packet.
<option>ACCEPT</option> means that the packet will be accepted.
<option>NOTRACK</option> indicates that no conntrack entry should be
created for the packet. <option>NOTRACK</option> does not imply
<option>ACCEPT</option>.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><emphasis role="bold">SOURCE</emphasis> - [<emphasis
role="bold">-</emphasis>|[$FW|<replaceable>interface</replaceable>]|[{$FW|interface}[<emphasis>:address</emphasis>[,<emphasis>address</emphasis>]...]]|[<emphasis>address</emphasis>[,<emphasis>address</emphasis>]...]</term>
<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 preceeded by a colon (":").</para>
<para>If left empty or supplied as "-", 0.0.0.0/0 is assumed.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><emphasis role="bold">DEST</emphasis> - [<emphasis
role="bold">-</emphasis>|[$FW|<replaceable>interface</replaceable>]|[{$FW|interface}[<emphasis>:address</emphasis>[,<emphasis>address</emphasis>]...]]|[<emphasis>address</emphasis>[,<emphasis>address</emphasis>]...]</term>
<listitem>
<para><option>$FW</option> matches packets addressed the firewall
itself, while <replaceable>interface</replaceable> specifies packets
arriving on the named interface. Neither may be specified if the
target is <option>NOTRACK</option>.</para>
<para>This column may also include a comma-separated list of
IP/subnet addresses. If your kernel and iptables include iprange
match support, IP address ranges are also allowed. Ipsets and
exclusion are also supported. When <option>$FW</option> or interface

</varlistentry>
<varlistentry>
<term>PROTO (Optional)
<replaceable>protocol-name-or-number</replaceable>[,...]</term>
<listitem>
<para>Protocol.</para>
<para>Beginning with Shorewall 4.5.12, this column can accept a
comma-separated list of protocols.</para>
</listitem>
</varlistentry>
<varlistentry>
<term>DEST PORT(S) (dport)
<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>
</listitem>
</varlistentry>
<varlistentry>
<term>SOURCE PORT(S) (sport)
<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 DEST PORT(S) 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).</para>
</listitem>
</varlistentry>

<note>
<para>The <emphasis role="bold">source</emphasis> and <emphasis
role="bold">dest</emphasis> options work best when used in conjunction
with ADMINISABSENTMINDED=Yes in <ulink
