ufw must be stopped after iface is powered off

Thank you for reporting the bug. It is a known issue that ufw is unloaded on shutdown, and a fix for this is planned.

This bug was fixed in the package ufw - 0.24

---------------
ufw (0.24) jaunty; urgency=low

  * debian/rules: check for 'nocheck' in DEB_BUILD_OPTIONS
  * debian/postrm: don't fail if iptables or ip6tables fails (LP: #278670)
  * fix typo in error message (LP: #280348)
  * allow case-insensitive matches for application rules (LP: #263757). Based
    on work by Didier Roche
  * add skel-ui for UI example
  * debian/postinst: don't stop in runlevels 0 and 6 (LP: #298736)
  * before6.rules: adjust hop limit to 255 for NDP messages (LP: #299268) per
    RFC 4890 secton 4.2. Thanks to Ryan Giobbi
  * before6.rules: restrict multicast (LP: #304216). Thanks to Ryan Giobbi
  * before.rules: don't use ctstate as it is not supported on all kernels and
    we don't use the extra information anyway (LP: #289906)
  * fix translations for input strings (LP: #302426)
  * update ucf md5sums for before.rules and before6.rules
  * adjust root/destructive tests for when we can't unmount /proc
