It's quite difficult to tell which rule catches your packets without the
ruleset. Try this:
1) Add "log" to all block rules
2) Check you have keep state in pass rules
3) Check you have quick in your pass rules
If you have a default block policy, then you should generally have quick
in pass rules or you might have packets marked for passing being caught
later by a block rule.
I generally prefer having the default policy at top without quick, and
then set quick on rules taking an explicit action.
