<p>The Shoreline Firewall, more commonly known as<61> "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>

</a>Jacques
Nilo and Eric Wolzak have a LEAF (router/firewall/gateway
on a floppy, CD or compact flash) distribution
called <i>Bering</i> that features
Shorewall-1.3.14 and Kernel-2.4.20. You can find
their work at: <a
href="http://leaf.sourceforge.net/devel/jnilo"> http://leaf.sourceforge.net/devel/jnilo</a></p>
<b>Congratulations
to Jacques and Eric on the recent release of Bering
1.1!!! <br>

<h2>News</h2>
<p><b>3/24/2003 - Shorewall 1.4.1 </b><b> </b><b><img
border="0" src="images/new10.gif" width="28" height="12" alt="(New)">
<20></b><b> </b></p>
<b> </b>
<ul>
</ul>
<p>This release follows up on 1.4.0. It corrects a problem introduced
in 1.4.0 and removes additional warts.<br>
<br>
<b>Problems Corrected:</b><br>
</p>
<ol>
<li>When Shorewall 1.4.0 is run under the ash shell (such as on Bering/LEAF),
it can attempt to add ECN disabling rules even if the /etc/shorewall/ecn file
is empty. That problem has been corrected so that ECN disabling rules are
only added if there are entries in /etc/shorewall/ecn.</li>
</ol>
<b>New Features:</b><br>
<blockquote>Note: In the list that follows, the term <i>group </i>refers
to a particular network or subnetwork (which may be 0.0.0.0/0 or it may be
a host address) accessed through a particular interface. Examples:<br>
<blockquote>eth0:0.0.0.0/0<br>
eth2:192.168.1.0/24<br>
eth3:192.0.2.123<br>
</blockquote>
You can use the "shorewall check" command to see the groups associated with
each of your zones.<br>
</blockquote>
<ol>
<li>Beginning with Shorewall 1.4.1, if a zone Z comprises more than
one group<i> </i>then if there is no explicit Z to Z policy and there are
no rules governing traffic from Z to Z then Shorewall will permit all traffic
between the groups in the zone.</li>
<li>Beginning with Shorewall 1.4.1, Shorewall will never create rules
to handle traffic from a group to itself.</li>
<li>A NONE policy is introduced in 1.4.1. When a policy of NONE is
specified from Z1 to Z2:</li>
</ol>
<ul>
<li>There may be no rules created that govern connections from Z1
to Z2.</li>
<li>Shorewall will not create any infrastructure to handle traffic
from Z1 to Z2.</li>
</ul>
See the <a href="upgrade_issues.htm">upgrade issues</a> for a discussion
of how these changes may affect your configuration.
