<p><a name="Install_RPM"></a>To install Shorewall using the RPM:</p>
<p><b>If you have RedHat 7.2 and are running iptables version 1.2.3 (at a
shell prompt, type "/sbin/iptables --version"), you must upgrade to version
1.2.4 either from the <a
href="http://www.redhat.com/support/errata/RHSA-2001-144.html">RedHat update
site</a> or from the <a href="errata.htm">Shorewall Errata page</a> before
attempting to start Shorewall.</b></p>
<ul>
<li>Install the RPM (rpm -ivh &lt;shorewall rpm&gt;).<br>
<br>
<b>Note: </b>Some SuSE users have encountered a problem whereby rpm
reports a conflict with kernel &lt;= 2.2 even though a 2.4 kernel is
installed. If this happens, simply use the --nodeps option to rpm (rpm
-ivh --nodeps &lt;shorewall rpm&gt;).</li>
<li>Edit the <a href="#Config_Files"> configuration files</a> to match
your configuration. <font color="#ff0000"><b>WARNING - YOU CAN <u>NOT</u>
SIMPLY INSTALL THE RPM AND ISSUE A "shorewall start" COMMAND. SOME CONFIGURATION
IS REQUIRED BEFORE THE FIREWALL WILL START. IF YOU ISSUE A "start" COMMAND
AND THE FIREWALL FAILS TO START, YOUR SYSTEM WILL NO LONGER ACCEPT ANY
NETWORK TRAFFIC. IF THIS HAPPENS, ISSUE A "shorewall clear" COMMAND TO
RESTORE NETWORK CONNECTIVITY.</b></font></li>
<li>Start the firewall by typing "shorewall start"</li>
</ul>
<p><a name="Install_Tarball"></a>To install Shorewall using the tarball
and install script: </p>
<ul>
<li>unpack the tarball (tar -zxf shorewall-x.y.z.tgz).</li>
<li>cd to the shorewall directory (the version is encoded in the
directory name as in "shorewall-1.1.10").</li>
<li>If you are using <a

href="http://www.redhat.com">RedHat</a>, <a
href="http://www.linux-mandrake.com">Mandrake</a>, <a

href="http://www.slackware.com/">Slackware</a> or <a
href="http://www.debian.org">Debian</a> then type "./install.sh"</li>
<li>If you are using <a href="http://www.suse.com">SuSe</a> then type
"./install.sh /etc/init.d"</li>
<li>If your distribution has directory /etc/rc.d/init.d
or /etc/init.d then type "./install.sh"</li>
<li>For other distributions, determine where your distribution
installs init scripts and type "./install.sh &lt;init script
directory&gt;</li>
<li>Edit the <a href="#Config_Files"> configuration files</a> to match
your configuration.</li>
<li>Start the firewall by typing "shorewall start"</li>
<li>If the install script was unable to configure Shorewall to be started
automatically at boot, see <a
href="starting_and_stopping_shorewall.htm">these instructions</a>.</li>
</ul>
<p><a name="LRP"></a>To install my version of Shorewall on a fresh Bering
disk, simply replace the "shorwall.lrp" file on the image with the file that
you downloaded. See the <a href="two-interface.htm">two-interface QuickStart
Guide</a> for information about further steps required.</p>
<p><a name="Upgrade_RPM"></a>If you already have the Shorewall RPM installed
and are upgrading to a new version:</p>
<p>If you are upgrading from a 1.2 version of Shorewall to a 1.3 version
and you have entries in the /etc/shorewall/hosts file then please check
your /etc/shorewall/interfaces file to be sure that it contains an entry
for each interface mentioned in the hosts file. Also, there are certain
1.2 rule forms that are no longer supported under 1.3 (you must use the
new 1.3 syntax). See <a href="errata.htm#Upgrade">the upgrade issues </a>for
details. You can check your rules and host file for 1.3 compatibility using
the "shorewall check" command after installing the latest version of 1.3.</p>
<ul>
<li>Upgrade the RPM (rpm -Uvh &lt;shorewall rpm file&gt;) <b>Note: </b>If
you are installing version 1.2.0 and have one of the 1.2.0 Beta RPMs
installed, you must use the "--oldpackage" option to rpm (e.g., "rpm
-Uvh --oldpackage shorewall-1.2-0.noarch.rpm").
<p> <b>Note: </b>Some SuSE users have encountered a problem whereby
rpm reports a conflict with kernel &lt;= 2.2 even though a 2.4 kernel
is installed. If this happens, simply use the --nodeps option to rpm (rpm
-Uvh --nodeps &lt;shorewall rpm&gt;).<br>
<20> </p>
</li>
<li>See if there are any incompatibilities between your configuration
and the new Shorewall version (type "shorewall check") and correct as necessary.</li>
<li>Restart the firewall (shorewall restart).</li>

<h3><a name="Config_Files"></a>Configuring Shorewall</h3>
<p>You will need to edit some or all of these configuration files to match
your setup. In most cases, the <a

<ul>
<li>/etc/shorewall/shorewall.conf - used to set several firewall
parameters.</li>

you will expand in other files.</li>
