<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 and can thus take advantage of
|
|
Netfilter's <a href=
|
|
"http://www.cs.princeton.edu/%7Ejns/security/iptables/iptables_conntrack.html"
|
|
target="_top">connection state tracking capabilities</a>.<br>
|
|
<br>
|
|
Shorewall is <u>not</u> a daemon. Once Shorewall has configured
|
|
Netfilter, it's job is complete. After that, there is no
|
|
Shorewall code running although the <a href=
|
|
"starting_and_stopping_shorewall.htm">/sbin/shorewall program
|
|
can be used at any time to monitor the Netfilter
|
|
firewall</a>.<br>
|
|
</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 style="margin-left: 40px;">
|
|
<li><a href=
|
|
"http://www.m0n0.ch/wall">http://www.m0n0.ch/wall</a></li>

|
|
|
|
</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.<br>

<h3><a name="GettingStarted"></a>Getting Started with
|
|
Shorewall</h3>
|
|
|
|
<p style="margin-left: 0.42in;">New to Shorewall? Start by
|
|
selecting the <a href=
|
|
"shorewall_quickstart_guide.htm">QuickStart Guide</a> that most
|
|
closely matches your environment and follow the step by step
|
|
instructions.</p>
|
|
|
|
<h3><a name="Info"></a>Looking for Information?</h3>
|
|
|
|
<p style="margin-left: 0.42in;">The <a href=
|
|
"Documentation_Index.html">Documentation Index</a> is a good
|
|
place to start as is the Site Search in the frame above.<br>

|
<h3><a name="Mandrake"></a>Running Shorewall on Mandrake® with
|
|
a two-interface setup?</h3>
|
|
|
|
<p style="margin-left: 0.42in;">If so, the documentation on
|
|
this site will not apply directly to your setup. If you want to
|
|
use the documentation that you find here, you will want to
|
|
consider uninstalling what you have and installing a setup that
|
|
matches the documentation on this site. See the <a href=
|
|
"two-interface.htm">Two-interface QuickStart Guide</a> for
|
|
details.<br>
|
|
<br>
|
|
<b>Update:</b> I have been informed by Mandrake Development
|
|
that this problem has been corrected in Mandrake 10.0 Final
|
|
(the problem still exists in the 10.0 Community release).</p>
