If PF is NATing the connections then by definition it's inline. There's
no other way to NAT for something where the packets don't go via the NAT
device.

If you mean the trapping function say by snort or suricata then that's
done by having a span port on a switch close to your egress/NAT device
(some vendors call it port mirror) and plugging into it another
interface on your PF box and setting that as 'monitor' in the interface
type.

In this case it's best if the PF box sees the un-natted connections so
it can trace it back to actual registrations.

Beyond that you'd need to describe what exactly you want to track - you
may find you need other tools like netflow and friends.
