<p>The Shoreline Firewall, more commonly known as "Shorewall", is
a <a href="http://www.netfilter.org">Netfilter</a> (iptables) based
firewall that can be used on a dedicated firewall system, a multi-function
gateway/router/server or on a standalone GNU/Linux system.</p>

<h2>Running Shorewall on Mandrake with a two-interface setup?</h2>
If so, almost <b>NOTHING </b>on this site will apply directly to your
setup. If you want to use the documentation that you find here, it is best
if you uninstall what you have and install a setup that matches the documentation
on this site. See the <a href="two-interface.htm">Two-interface QuickStart
Guide</a> for details.<br>
<h2> Getting Started with Shorewall</h2>
New to Shorewall? Start by selecting the <a
href="shorewall_quickstart_guide.htm">QuickStart Guide</a> that most closely
match your environment and follow the step by step instructions.<br>
<h2>News</h2>
<p><b>5/20/2003 - Shorewall-1.4.3a</b><b> </b><b><img border="0"
src="images/new10.gif" width="28" height="12" alt="(New)">
</b><b> </b><br>
</p>
This version primarily corrects the documentation included in the .tgz and
in the .rpm. In addition: <br>
<ol>
<li>(This change is in 1.4.3 but is not documented) If you are running
iptables 1.2.7a and kernel 2.4.20, then Shorewall will return reject replies
as follows:<br>
<EFBFBD><EFBFBD> a) tcp - RST<br>
<EFBFBD><EFBFBD> b) udp - ICMP port unreachable<br>
<EFBFBD><EFBFBD> c) icmp - ICMP host unreachable<br>
<EFBFBD><EFBFBD> d) Otherwise - ICMP host prohibited<br>
If you are running earlier software, Shorewall will follow it's traditional
convention:<br>
<EFBFBD><EFBFBD> a) tcp - RST<br>
<EFBFBD><EFBFBD> b) Otherwise - ICMP port unreachable</li>
<li>UDP port 135 is now silently dropped in the common.def chain.
Remember that this chain is traversed just before a DROP or REJECT policy
is enforced.<br>
</li>
</ol>
<p><b>5/18/2003 - Shorewall 1.4.3 </b><b><img border="0"
src="images/new10.gif" width="28" height="12" alt="(New)">
</b><br>
</p>
<20><><EFBFBD> <b>Problems Corrected:<br>
</b>
<ol>
<li>There were several cases where Shorewall would fail to remove
a temporary directory from /tmp. These cases have been corrected.</li>
<li>The rules for allowing all traffic via the loopback interface
have been moved to before the rule that drops status=INVALID packets. This
insures that all loopback traffic is allowed even if Netfilter connection
tracking is confused.</li>
</ol>
<20><><EFBFBD> <b>New Features:<br>
</b>
<ol>
<li><EFBFBD><a href="6to4.htm">IPV6-IPV4 (6to4) tunnels are</a> now supported
in the /etc/shorewall/tunnels file.</li>
<li>Shorewall can now be easily integrated with fireparse (http://www.fireparse.com)
by setting LOGMARKER="fp=" in <a href="Documentation.htm#Conf">/etc/shorewall/shorewall.conf.</a>
Note: You may not use ULOG with fireparse unless you modify fireparse. </li>

<p><b>4/26/2003 - lists.shorewall.net Downtime</b><b> </b></p>
<p>The list server will be down this morning for upgrade to RH9.0.<br>
</p>
<p><b>4/21/2003 - Samples updated for Shorewall version 1.4.2</b><b>
</b></p>
<p>Thanks to Francesca Smith, the sample configurations are now upgraded

<p><b>4/12/2002 - Greater Seattle Linux Users Group Presentation</b><b>
</b></p>
<blockquote>This morning, I gave <a href="GSLUG.htm" target="_top">a
Shorewall presentation to GSLUG</a>. The presentation is
in HTML format but was generated from Microsoft PowerPoint and is best
viewed using Internet Explorer (although Konqueror also seems to work
reasonably well as does Opera 7.1.0). Neither Opera 6 nor Netscape work
well to view the presentation.<br>
