I looked at /usr/share/examples/ipfilter/ on FreeBSD-8.4, 9.3, 10.1 and I did not see anything different in those files. Now, my rules work quite well on 8.4, 9.3, but fail in 10.1 I have been using these rules forever on many many boxes and all I was doing is to edit ipnat.conf and ipfilter.conf to change the interface names and the IPs/subnets for the LAN/WAN.
