What do you mean "packets being dropped by pf that should not traverse
the bridge at all"? Some clarity would help here.
Are you saying:
(host 1, host 2) <--------> (int_1 OBSD Box int_2) <---------> (other hosts)
And that packes from host 1 to host 2 (and vice versa) are showing as
being dropped on int_2? If so, outbound? By a block rule?
Topology and a pf.conf file will get you more help. . .
