<h2>The Guides</h2>
|
|
|
|
|
<p>These guides provide step-by-step instructions for configuring Shorewall in
|
|
|
|
|
common firewall setups.</p>
|
|
|
|
|
<p>The following guides are for firewalls with a single external IP address:</p>
|
|
|
|
|
<ul>
|
|
|
|
|
<li><a href="standalone.htm">Standalone</a> Linux System</li>
|
|
|
|
|
<li><a href="two-interface.htm">Two-interface</a> Linux System acting as a

firewall/router for a small local network</li>

<li><a href="three-interface.htm">Three-interface</a> Linux System acting as a

|
|
|
|
firewall/router for a small local network and a DMZ.</li>
|
|
|
|
|
</ul>
|
|
|
|
|
<p>The above guides are designed to get your first firewall up and running
|
|
|
|
|
quickly in the three most common Shorewall configurations.</p>

|
|
|
|
|
the steps necessary to set up a firewall where there are multiple public IP
|
|
|
|
|
addresses involved or if you want to learn more about Shorewall than is
|
|
|
|
|
explained in the single-address guides above.</p>
