Someone else may have keener eyes, but for my part I can't guess what the problem
could be from your description.

Can you send your entire ipfw ruleset?  (i.e. the complete output of 'ipfw show')
Perhaps then I'll be able to get a better idea what you're doing.  If 10562 is
catching packets, then it's likely that it's somewhere else that the problem lie.
