I use the log statement to see what a rule is doing: block in log quick on em0 from 83.0.0.0/8 to any or just to be really sure it's working, try: block in log quick on em0 Use ipmon -D "my_block.log" to keep track of what ipf is trying to do... Also, NAT rule get processed first, so make sure NAT isn't throwing you a curve. There are some specific configurations for FreeBSD I think (I use NetBSD)...
