It's quite possible the kernel wasn't compiled with firewalling enabled.
First read up on the whole firewall setup thing:
http://www.freebsd.org/handbook/firewalls.html
There's a link in the section on configuring your kernel to the
"building a kernel" section of the handbook, so if you're not familiar
with that process you can read that as well.

Hope this helps,
Bill
