<p>iptables - the utility program used to configure and control

Netfilter. The term 'iptables' is often used to refer to the

combination of iptables+Netfilter (with Netfilter not in ipchains

compatibility mode). </p>

<h3><a name="WhatIs"></a>What is Shorewall?</h3>
|
|
<p style="margin-left: 0.42in;">The Shoreline Firewall, more commonly
|
|
known as "Shorewall", is a high-level tool for configuring
|
|
Netfilter. You describe your firewall/gateway requirements using
|
|
entries in a set of configuration files. Shorewall reads those
|
|
configuration files and with the help of the iptables utility,
|
|
Shorewall configures Netfilter to match your requirements. Shorewall
|
|
can be used on a dedicated firewall system, a multi-function
|
|
gateway/router/server or on a standalone GNU/Linux system. Shorewall
|
|
does not use Netfilter's ipchains compatibility mode and can thus
|
|
take advantage of Netfilter's <a
|
|
href="http://www.cs.princeton.edu/%7Ejns/security/iptables/iptables_conntrack.html"
|
|
target="_top">connection
|
|
state tracking capabilities</a>.<br>
|
|
<br>
|
|
Shorewall is <u>not</u> a
|
|
daemon. Once Shorewall has configured Netfilter, it's job is
|
|
complete. After that, there is no Shorewall code running although the
|
|
<a href="starting_and_stopping_shorewall.htm">/sbin/shorewall program
|
|
can be used at any time to monitor the Netfilter firewall</a>.</p>
|
|
<h3><a name="GettingStarted"></a>Getting Started with Shorewall</h3>
|
|
<p style="margin-left: 0.42in;">New to Shorewall? Start by selecting
|
|
the <a href="shorewall_quickstart_guide.htm">QuickStart Guide</a>
|
|
that most closely matches your environment and follow the step by
|
|
step instructions.</p>
|
|
<h3><a name="Info"></a>Looking for Information?</h3>
|
|
<p style="margin-left: 0.42in;">The <a href="Documentation_Index.html">Documentation
|
|
Index</a> is a good place to start as is the Quick Search in the
|
|
frame above. </p>
|
|
<h3><a name="Mandrake"></a>Running Shorewall on Mandrake® with a
|
|
two-interface setup?</h3>
|
|
<p style="margin-left: 0.42in;">If so, the documentation on this site
|
|
will not apply directly to your setup. If you want to use the
|
|
documentation that you find here, you will want to consider
|
|
uninstalling what you have and installing a setup that matches the
|
|
documentation on this site. See the <a href="two-interface.htm">Two-interface
|
|
QuickStart Guide</a> for details.<br>
|
|
<br>
|
|
<b>Update: </b>I've been
|
|
informed by Mandrake Development that this problem has been corrected
|
|
in Mandrake 10.0 Final (the problem still exists in the 10.0
|
|
Community release).</p>

Shorewall 2.0.15<br>

Problems Corrected:<br>
|
|
<ol>
|
|
<li>The range of ports opened by the AllowTrcrt action has been
|
|
expanded to 33434:33524 to allow for a maximum of 30 hops.</li>
|
|
<li>Code mis-ported from 2.2.0 in release 2.0.14 caused the following
|
|
error during "shorewall start" where SYN rate-limiting is present in
|
|
/etc/shorewall/policy:<br>
|
|
<br>
|
|
Bad argument `DROP'<br>

Try `iptables -h' or 'iptables --help'

Shorewall 2.0.14<br>
|
|
</span><br>
|
|
New Features:<br>
|
|
<ol>
|
|
<li>Previously, when rate-limiting was specified in
|
|
/etc/shorewall/policy (LIMIT:BURST column), any traffic which exceeded
|
|
the specified rate was silently dropped. Now, if a log level is given
|
|
in the entry (LEVEL column) then drops are logged at that level at a
|
|
rate of 5/min with a burst of 5.<br>
|
|
</li>
|
|
</ol>
|
|
Problems Corrected:<br>
|
|
<ol>
|
|
<li>A typo in the /etc/shorewall/interfaces file has been fixed.</li>
|
|
<li>"bad variable" error messages occurring during "shorewall stop"
|
|
and "shorewall clear" have been eliminated.</li>
|
|
<li>A misleading typo in /etc/shorewall/tunnels has been corrected.
|
|
The TYPE column for an IPIP tunnel should contain "ipip" rather than
|
|
"ip".<br>

Problems Corrected:<br>

|
changed to use the RATE LIMIT column.</li>
|
|
<li>Entries in /etc/shorewall/masq with the INTERFACE column

|
containing <ifname>:: (e.g., "eth0::") would generate a progress
