Recognize that the version of
pf(4) found on FreeBSD is usually a generation or two
older than what is available on OpenBSD. Hansteen acknowledges this, but other less informative Internet sources don't.
pf(4) is not the same across the *BSD family.
Development on
pf(4) is aggressive on OpenBSD.
pf(4) has undergone a number of syntax changes during recent OpenBSD versions. I expect this trend to continue indefinitely.
The Book of PF is based on Hansteen's manuscript, however the book is a few years old now as a second edition will be published tentatively in August 2010. Because of this, I would not recommend the first edition. Otherwise, the first edition was one of the better sources of
pf(4) information.
If you have other questions about networking, it will help if you post a diagram of your network including interface names & IP addresses. This will help clarify topology & subnetting correctness.
