<title>What is Shorewall?</title>
|
|
|
|
<para>The Shoreline Firewall, more commonly known as
|
|
"Shorewall", 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>
