Seeing snippet of your firewall rules is not giving us enough info
to work on.
You have to post complete rule set because of the way rules are
processed.
Also an explanation of your private network layout and how you
connect to the internet is needed.

The ipfw rules standing without any other rules and '65535 allow ip from
