<caution>
<para>Some users are in the habit of using the <command>rpm
-U</command> command for installing packages as well as for updating
them. If you use that command when installing the Shorewall RPM then
you will have to manually enable Shorewall startup at boot time by
running <command>chkconfig</command>, <command>insserv</command> or
whatever utility you use to manipulate you init symbolic
links.</para>

<note>
<para>Shorewall is dependent on the iproute package. Unfortunately,
some distributions call this package iproute2 which will cause the
installation of Shorewall to fail with the diagnostic:</para>
<programlisting>error: failed dependencies:iproute is needed by shorewall-3.2.x-1</programlisting>
<para>This problem should not occur if you are using the correct RPM
package (see 1., above) but may be worked around by using the
--nodeps option of rpm.</para>

<para>Most problems associated with upgrades come from two causes:</para>

<listitem>
<para>The user didn't read and follow the migration considerations in
the release notes (these are also reproduced in the <ulink
url="upgrade_issues.htm">Shorewall Upgrade Issues</ulink>).</para>
</listitem>
<listitem>
<para>The user mis-handled the
<filename>/etc/shorewall/shorewall.conf</filename> file during
upgrade. Shorewall is designed to allow the default behavior of the
product to evolve over time. To make this possible, the design assumes
that <emphasis role="bold">you will not replace your current
shorewall.conf</emphasis> <emphasis role="bold">file during
upgrades</emphasis>. It is recommended that after you first install
Shorewall that you modify
<filename>/etc/shorewall/shorewall.conf</filename> so as to prevent
your package manager from overwriting it during subsequent upgrades
(since the addition of STARTUP_ENABLED, such modification is assured
since you must manually change the setting of that option). If you
feel absolutely compelled to have the latest options in your
shorewall.conf then you must proceed carefully. You should determine
which new options have been added and you must reset their value (e.g.
OPTION=""); otherwise, you will get different behavior from what you
expect.</para>
