I am not sure I follow, can you rephrase/state the above ? Do you mean
the quick pass rule is not being evaluated, even if its the very first
rule ? perhaps illustrate the condition with a minimal set of pf rules?
If you dont use the pass in {rdr|binat|nat} and make the quick line the
first line, nothing should get evaluated after the quick pass.
Also, I would always add 'log' to all the rules when debugging, so you
see whats actually being hit. There should not be any mysteries that way.
