I haven't used UFW, but I'm looking at the documentation here:

  https://help.ubuntu.com/community/UFW

and it seems that the order of the rules is important.  Quote:

  Once a rule is matched the others will not be evaluated (see manual
  below) so you must put the specific rules first. As rules change you
  may need to delete old rules to ensure that new rules are put in the
  proper order. 

and from the man page:

  Rule ordering is important and the first match wins. Therefore when
  adding rules, add the more specific rules first with more general
  rules later.
