I'm not sure, but since you use natd, panics may be related to ip_divert
module. If KTLS somehow is used in your environment, this means unmapped
mbufs also can be used.

You can try to reconfigure your ipfw rules to use in-kernel NAT instead
of natd.

Also you can try to disable unmapped mbufs:
sysctl kern.ipc.mb_use_ext_pgs=0
