---------------------------------------------

Looking over it I can't see any obvious mistakes.
Have you enabled pf, (e.g. done "pfctl -e") ?
And can you provide the output of "pfctl -sr".
A good way to narrow your problem down would be to log all rules that
pass and see which one lets outside connections in.
