With the it depends on how you configure net.inet.ip.fw.one_pass (also documented in that page). The default setting is to act as for bridging (and btw forcing one pass for bridging is just because i did not have the time to check that it works otherwise, but it really should). cheers luigi > BRIDGE implementation, this would behave exclusively (one pipe per packet) > as a pipe implies an accept, but in the non-BRIDGE implementation, it > would allow multiple pipes per packet.
