<para>If you install using the .deb, you will find that your <filename
class="directory">/etc/shorewall</filename> directory is empty. This is
intentional. The released configuration file skeletons may be found on
your system in the directory <filename class="directory">/usr/share/doc/shorewall/default-config</filename>.
Simply copy the files you need from that directory to <filename
class="directory">/etc/shorewall</filename> and modify the copies.</para>
<para>Note that you must copy <filename class="directory">/usr/share/doc/shorewall/default-config/shorewall.conf</filename>
and /usr/share/doc/shorewall/default-config/modules to <filename
class="directory">/etc/shorewall</filename> even if you do not modify
those files.</para>

iproute2 which will cause the installation of Shorewall to fail with
