<h1 style="text-align: center;">Ports Required for Various
|
||
Services/Applications<br>
|
||
</h1>
|
||
<p>In addition to those applications described in <a
|
||
href="Documentation.htm">the /etc/shorewall/rules documentation</a>,
|
||
here are some other services/applications that you may need to
|
||
configure
|
||
your firewall to accommodate.</p>
|
||
<p>NTP (Network Time Protocol)</p>
|
||
<blockquote>
|
||
<p>UDP Port 123</p>
|
||
</blockquote>
|
||
<p>rdate</p>
|
||
<blockquote>
|
||
<p>TCP Port 37</p>
|
||
</blockquote>
|
||
<p>UseNet (NNTP)</p>
|
||
<blockquote>
|
||
<p>TCP Port 119</p>
|
||
</blockquote>
|
||
<p>DNS</p>
|
||
<blockquote>
|
||
<p>UDP Port 53. If you are configuring a DNS client, you will
|
||
probably
|
||
want to open TCP Port 53 as well.<br>
|
||
If you are configuring a server, only open TCP Port 53 if
|
||
you will return long replies to queries or if you need to enable ZONE
|
||
transfers. In the latter case, be sure that your server is
|
||
properly
|
||
configured.</p>
|
||
</blockquote>
|
||
<p>ICQ </p>
|
||
<blockquote>
|
||
<p>UDP Port 4000. You will also need to open a range of TCP ports
|
||
which you can specify to your ICQ client. By default, clients use
|
||
4000-4100.</p>
|
||
</blockquote>
|
||
<p>PPTP</p>
|
||
<blockquote>
|
||
<p><u>Protocol</u> 47 (NOT <u>port</u> 47) and TCP Port 1723 (<a
|
||
href="PPTP.htm">Lots more information here</a>).</p>
|
||
</blockquote>
|
||
<p>IPSEC</p>
|
||
<blockquote>
|
||
<p><u>Protocols</u> 50 and 51 (NOT <u>ports</u> 50 and 51) and UDP
|
||
Port 500. These should be opened in both directions (Lots more
|
||
information <a href="IPSEC.htm">here</a> and <a href="VPN.htm">here</a>).</p>
|
||
</blockquote>
|
||
<p>SMTP (Email)</p>

<p>NFS<br>
|

</p>
|

<blockquote>
|
||
<p>I personally use the following rules for opening access from zone
|
||
z1 to a server with IP address a.b.c.d in zone z2:<br>
|
||
</p>
|
||
<pre>ACCEPT z1 z2:a.b.c.d udp 111<br>ACCEPT z1 z2:a.b.c.d tcp 111<br>ACCEPT z1 z2:a.b.c.d udp 2049<br>ACCEPT z1 z2:a.b.c.d udp 32700:<br></pre>
|
||
</blockquote>
|
||
<blockquote>
|
||
<p>Note that my rules only cover NFS using UDP (the normal case).
