<para>If you specify an address here, matching packets will
have their source address set to that address. If
ADD_SNAT_ALIASES is set to Yes or yes in <ulink
url="/manpages/shorewall.conf.html">shorewall.conf</ulink>(5)
then Shorewall will automatically add this address to the
INTERFACE named in the first column.</para>
<para>You may also specify a range of up to 256 IP addresses
if you want the SNAT address to be assigned from that range in
a round-robin fashion by connection. The range is specified by
<emphasis>first.ip.in.range</emphasis>-<emphasis>last.ip.in.range</emphasis>.
You may follow the port range with<emphasis role="bold">
:random</emphasis> in which case assignment of ports from the
list will be random. <emphasis role="bold">random</emphasis>
may also be specified by itself in this column in which case
random local port assignments are made for the outgoing
connections.</para>
<para>Example: 206.124.146.177-206.124.146.180</para>
<para>You may follow the port range (or <emphasis
role="bold">:random</emphasis>) with <emphasis
role="bold">:persistent</emphasis>. This is only useful when
an address range is specified and causes a client to be given
the same source/destination IP pair. This feature replaces the
SAME modifier which was removed from Shorewall in version
4.4.0.</para>
<para>You may also use the special value
<option>detect</option> which causes Shorewall to determine
the IP addresses configured on the interface named in the DEST
column and substitute them in this column.</para>
<para>Finally, you may also specify a comma-separated list of
ranges and/or addresses in this column.</para>
<para>DNS Names names are not allowed.</para>
<para>Normally, Netfilter will attempt to retain the source
port number. You may cause netfilter to remap the source port
by following an address or range (if any) by ":" and a port
range with the format
<emphasis>lowport</emphasis>-<emphasis>highport</emphasis>. If
this is done, you must specify "tcp", "udp", "dccp" or "stcp"
in the PROTO column.</para>

<para>The interface may be qualified by adding the character ":"

PERL....END PERL in configuration files, the only way to execute a

facility has the drawback that the compiler will attempt to run a
non-script file just because it has the same name as a chain. To
disable this facility, set CHAIN_SCRIPTS=No. If not specified or
