Netfilter. The term 'iptables' is often used to refer to the combination

of iptables+Netfilter (with Netfilter not in ipchains compatibility

mode).</p>

<h3><a name="WhatIs"></a>What is Shorewall?</h3>
|
||
|
||
<p style="margin-left: 0.42in;">The Shoreline Firewall, more commonly known
|
||
as "Shorewall", is a high-level tool for configuring Netfilter. You describe
|
||
your firewall/gateway requirements using entries in a set of configuration
|
||
files. Shorewall reads those configuration files and with the help of the
|
||
iptables utility, Shorewall configures Netfilter to match your requirements.
|
||
Shorewall can be used on a dedicated firewall system, a multi-function
|
||
gateway/router/server or on a standalone GNU/Linux system. Shorewall does not
|
||
use Netfilter's ipchains compatibility mode; as a consequence, Shorewall can
|
||
take advantage of Netfilter's connection state tracking capabilities to
|
||
create a stateful firewall.<br>
|
||
<br>
|
||
Shorewall is <u>not</u> a daemon. Once Shorewall has configured Netfilter,
|
||
it's job is complete and there is no Shorewall code left running in the
|
||
system. The <a href="starting_and_stopping_shorewall.htm">/sbin/shorewall
|
||
program can be used at any time to monitor the Netfilter firewall</a>.</p>
|
||
|
||
<p style="margin-left: 0.42in;">Shorewall is not the easiest to use of the
|
||
available iptables configuration tools but I believe that it is the most
|
||
flexible and powerful. So if you are looking for a simple point-and-click
|
||
set-and-forget Linux firewall solution that requires a minimum of networking
|
||
knowledge, I would encourage you to check out the following alternatives:</p>
|
||
<ul>
|
||
<li><p style="margin-bottom: 0in;"><a
|
||
href="http://www.m0n0.ch/wall">m0n0wall</a> (FreeBSD Based) </p>
|
||
</li>
|
||
<li><p><a href="http://www.fs-security.com/">Firestarter</a></p>
|
||
</li>
|
||
</ul>
|
||
|
||
<p style="margin-left: 0.42in;">On the other hand, if you are looking for a
|
||
Linux firewall solution that can handle complex and fast changing network
|
||
environments then Shorewall is a logical choice.</p>
|
||
|
||
<p style="margin-left: 0.42in;">To see some of the many things that you can

||
