You have to use PFIL_HOOKS _OR_ ipfilter.
PFIL_HOOKS is for the lkm driver and the pseudo-device is for the
kernel driver of ipf/ipnat.

You also have to enable ipf in /etc/rc.conf because ipnat needs a runing
ipf. And don't forget to create a empty /etc/ipf.conf file, because
/etc/netstart checks if this file exists and aborts if it doesn't find it.
