The impact you receive is caused by user-level 'natd'. Use 'ipnat(8)'
instead as it is kernel-level, or as mentioned use 'pf(4)'. Of course
use it without 'ipfw add divert' rule by saving the overall role of
'ipfw' in your firewalling.
As an addition, you may use 'ipnat', 'ipfw' and 'pf' and seems even
'ipf' together the same time (with some precautions, try to find the
information on it, I know it was there). Just using needed specific
features of each of them where it is needed.
Try it. Use it.
