--- Comment #3 from Vincenzo Maffione <vmaffione at FreeBSD.org> ---
I see. The behaviour you are observing is expected, because netmap is a kernel
bypass solution. This means that packets are transmitted from user-space to the
NIC without going through the normal kernel stack datapath, including pf/ipfw
and similar.
The reason for bypassing everything is efficiency (at least assuming that your
IPS interface has native netmap support).
In other words it is not doable to get the behaviour that you are looking for.
