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> </listitem> </itemizedlist> </section> <section id="Upgrade_RPM"> <title>Upgrade using RPM</title> <para>If you already have the Shorewall RPM installed and are upgrading to a new version:</para> <orderedlist> <listitem> <para><emphasis role="bold">Be sure that you have the correct RPM package!</emphasis></para> <para>The standard RPM package from shorewall.net and the mirrors is known to work with <trademark>SUSE</trademark>, Power PPC, Trustix and TurboLinux.
