<h2 align="left">What is it?</h2>
<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

<p><b>5/29/2003 - Shorewall-1.4.4b</b><b> </b><b><img border="0"
src="images/new10.gif" width="28" height="12" alt="(New)">
</b></p>
<p>Groan -- This version corrects a problem whereby the --log-level
was not being set when logging via syslog. The most commonly reported symptom
was that Shorewall messages were being written to the console even though
console logging was correctly configured per <a href="FAQ.htm#faq16">FAQ
16</a>.<br>
</p>
<p><b>5/27/2003 - Shorewall-1.4.4a</b><b> </b><b><img border="0"
src="images/new10.gif" width="28" height="12" alt="(New)">
</b></p>
The Fireparse --log-prefix fiasco continues. Tuomo Soini has pointed out
that the code in 1.4.4 restricts the length of short zone names to 4 characters.
I've produced version 1.4.4a that restores the previous 5-character limit
by conditionally omitting the log rule number when the LOGFORMAT doesn't
contain '%d'.
<p><b>5/23/2003 - Shorewall-1.4.4</b><b> </b><b><img border="0"
src="images/new10.gif" width="28" height="12" alt="(New)">
</b><b> </b></p>
I apologize for the rapid-fire releases but since there is a potential
configuration change required to go from 1.4.3a to 1.4.4, I decided to
make it a full release rather than just a bug-fix release. <br>
<br>
<b>��� Problems corrected:</b><br>
<blockquote>None.<br>
</blockquote>
<b>��� New Features:<br>
</b>
<ol>
<li>A REDIRECT- rule target has been added. This target behaves
for REDIRECT in the same way as DNAT- does for DNAT in that the Netfilter
nat table REDIRECT rule is added but not the companion filter table ACCEPT
rule.<br>
<br>
</li>
<li>The LOGMARKER variable has been renamed LOGFORMAT and has
been changed to a 'printf' formatting template which accepts three arguments
(the chain name, logging rule number and the disposition). To use LOGFORMAT
with fireparse (<a href="http://www.fireparse.com">http://www.fireparse.com</a>),
set it as:<br>
�<br>
������ LOGFORMAT="fp=%s:%d a=%s "<br>
�<br>
<b>CAUTION: </b>/sbin/shorewall uses the leading part of the LOGFORMAT
string (up to but not including the first '%') to find log messages in the
'show log', 'status' and 'hits' commands. This part should not be omitted
(the LOGFORMAT should not begin with "%") and the leading part should be
sufficiently unique for /sbin/shorewall to identify Shorewall messages.<br>
<br>
</li>
<li>When logging is specified on a DNAT[-] or REDIRECT[-] rule,
the logging now takes place in the nat table rather than in the filter table.
This way, only those connections that actually undergo DNAT or redirection
will be logged.<br>
</li>
</ol>
<p><b>5/20/2003 - Shorewall-1.4.3a</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>
�� a) tcp - RST<br>
�� b) udp - ICMP port unreachable<br>
�� c) icmp - ICMP host unreachable<br>
�� d) Otherwise - ICMP host prohibited<br>
If you are running earlier software, Shorewall will follow it's traditional
convention:<br>
�� a) tcp - RST<br>
�� 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><br>
</p>
��� <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>
��� <b>New Features:<br>
</b>
<ol>
<li>�<a href="6to4.htm">IPV6-IPV4 (6to4) tunnels are</a>
now supported in the /etc/shorewall/tunnels file.</li>
<li>You may now change the leading portion of the --log-prefix
used by Shorewall using the LOGMARKER variable in shorewall.conf. By default,
"Shorewall:" is used.<br>
</li>
</ol>

<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>
