Although I suck at IPF myself and haven't managed to tighten
up my own firewall properly without breaking everything there
is, I recommend the quite easily understood IPF HOWTO you'll
find a link to in the documentation section of http://www.netbsd.org/

It's quite lengthy and makes things seem really simple (at least until
you discover nothing works and you have to keep reading... ;) ).

Among other things, it explains that the "quick" keyword means
to short-circuit the evaluation (i.e. if a matching rule is found
and it has the "quick" keyword, no further comparisons are made; in
this case, your blocking ep1 out rules).

Good luck
