<title>Important Notes</title>

<note>
|
|
<para>Shorewall distribution contains a library of user-defined macros
|
|
that allow for easily allowing or blocking a particular application.
|
|
<command>ls <filename>/usr/share/shorewall/</filename>macro.*</command>
|
|
for the list of macros in your distribution. If you find what you need,
|
|
you simply use the macro in a rule. For example, to allow DNS queries
|
|
from the <emphasis role="bold">dmz</emphasis> zone to the <emphasis
|
|
role="bold">net</emphasis> zone:</para>
|
|
|
|
<programlisting>#ACTION SOURCE DESTINATION
|
|
DNS/ACCEPT dmz net</programlisting>
|
|
</note>
|
|
|
|
<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>
|
|
|
|
<programlisting>#ACTION SOURCE DESTINATION PROTO DEST PORT(S)
|
|
FTP/ACCEPT <emphasis><source></emphasis> <emphasis><destination></emphasis></programlisting>
|
|
|
|
<para>You would code your rule as follows:</para>

|
|
<programlisting>#ACTION SOURCE DESTINATION PROTO DEST PORT(S)
|
|
FTP/DNAT net dmz:192.168.1.4 </programlisting>

|

<para>Note that if you are setting up a DNS server that supports recursive
|
|
resolution, the server is the <<emphasis>destination</emphasis>> for
|
|
resolution requests (from clients) and is also the
|
|
<<emphasis>source</emphasis>> of recursive resolution requests
|
|
(usually to other servers in the 'net' zone). So for example, if you have
|
|
a public DNS server in your DMZ that supports recursive resolution for
|
|
local clients then you would need:</para>
|
|
|
|
<programlisting>#ACTION SOURCE DESTINATION PROTO DEST PORT(S)
|
|
DNS/ACCEPT all dmz
|
|
DNS/ACCEPT dmz net </programlisting>
|
|
|
|
<note>
|
|
<para>Recursive Resolution means that if the server itself can't resolve
|
|
the name presented to it, the server will attempt to resolve the name
|
|
with the help of other servers.</para>
