I would also recommend buying the book "Building Linux and OpenBSD Firewalls" by Wes Sonnenreich and Tom Yates, Wiley 2000. Most of the info on OpenBSD is applicable to FreeBSD. It is excellent. FreeBSD has kernel support (see LINT) for IPFilter, which the book explains in depth. There is also a wealth of info in it on the various types of security exploits. Rob.
