<note>

<para>In the rules that are shown in this document, the ACTION is shown as
|
|
ACCEPT. You may need to use DNAT (see <ulink url="FAQ.htm#faq30">FAQ 30</ulink>)
|
|
or you may want DROP or REJECT if you are trying to block the application.</para>
|
|
|
|
<para>Example: You want to port forward FTP from the net to your server at
|
|
192.168.1.4 in your DMZ. The FTP section below gives you:</para>

ACCEPT <emphasis><source></emphasis> <emphasis><destination></emphasis> tcp 21</programlisting>
|
|
|
|
<para>You would code your rule as follows:</para>

|
|
|
<programlisting>#ACTION SOURCE DESTINATION PROTO DEST PORT(S)
