<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>

<20><><EFBFBD> <b>Problems Corrected:<br>

<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>

<p><b>4/21/2003 - Samples updated for Shorewall version 1.4.2</b><b>

<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.</blockquote>
<p><b></b></p>
<blockquote>
<ol>
<li>TCP connection requests rejected out of the <b>common</b> chain
are now properly rejected with TCP RST; previously, some of these requests
were rejected with an ICMP port-unreachable response.</li>
<li>'traceroute -I' from behind the firewall previously timed out
on the first hop (e.g., to the firewall). This has been worked around.</li>
</ol>
</blockquote>
<p><b><EFBFBD><EFBFBD><EFBFBD> New Features:</b></p>
<blockquote>
<ol>
<li>Where an entry in the/etc/shorewall/hosts file specifies a
particular host or network, Shorewall now creates an intermediate chain for
handling input from the related zone. This can substantially reduce the number
of rules traversed by connections requests from such zones.<br>
<br>
</li>
<li>Any file may include an INCLUDE directive. An INCLUDE directive
consists of the word INCLUDE followed by a file name and causes the contents
of the named file to be logically included into the file containing the INCLUDE.
File names given in an INCLUDE directive are assumed to reside in /etc/shorewall
or in an alternate configuration directory if one has been specified for the
command. <br>

<20><> ----- end rules -----<br>
<20><br>
INCLUDE's may be nested to a level of 3 -- further nested INCLUDE directives
are ignored with a warning message.<br>
<br>
</li>
<li>Routing traffic from an interface back out that interface continues
to be a problem. While I firmly believe that this should never happen, people
continue to want to do it. To limit the damage that such nonsense produces,
I have added a new 'routeback' option in /etc/shorewall/interfaces and /etc/shorewall/hosts.
When used in /etc/shorewall/interfaces, the 'ZONE' column may not contain
'-'; in other words, 'routeback' can't be used as an option for a multi-zone
interface. The 'routeback' option CAN be specified however on individual group
entries in /etc/shorewall/hosts.<br>
<20><br>
The 'routeback' option is similar to the old 'multi' option with two exceptions:<br>
<20><br>
<20><> a) The option pertains to a particular zone,interface,address tuple.<br>
<20><br>
<20><> b) The option only created infrastructure to pass traffic from (zone,interface,address)
tuples back to themselves (the 'multi' option affected all (zone,interface,address)
tuples associated with the given 'interface').<br>
<20><br>
See the '<a href="file:///Z:/Shorewall-docs/upgrade_issues.htm">Upgrade
Issues</a>' for information about how this new option may affect your configuration.<br>
