<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>

network environments then Shorewall is a logical choice.<br>
