I would make sure all your rules apply to the external interface
only so they don't apply any restrictions to your internal hosts
talking to the internal interface. In particular it looks like
your last default deny rule will match any traffic going anywherere.

Not sure why this is not working as I'm not familiar with the
ipfw syntax. You should be able to get some logging of where
the packets are being dropped, and hopefully it should show
you which rule is causing them to be blocked.
