For production Freebsd based firewalls I have always built the kernel with PF. The idea being that if something does go pear shaped, there's a good chance that at least the packet filter will stay operational. OpenBSDs standard pre loaded /etc/rc filter (which drops everything except ssh & IIRC dns) would also be nice, but my understanding is that to implement it on Free would break the startup elsewhere.
