<title>What is Shorewall?</title>
|
|
|
|
<para>The Shoreline Firewall, more commonly known as <quote>Shorewall</quote>,
|
|
is 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 connection state
|
|
tracking capabilities.</para>
|
|
|
|
<para>Shorewall is not a daemon. Once Shorewall has configured
|
|
Netfilter, it's job is complete although the <ulink
|
|
url="starting_and_stopping_shorewall.htm">/sbin/shorewall program can be
|
|
used at any time to monitor the Netfilter firewall</ulink>.</para>
