Here you can also find the more extensive BSDCan 2016 slides (slides for the June 8, 2016 tutorial, covers modern PF as well as pre- OpenBSD 4.7, up to date with OpenBSD 6.0), also see The Book of PF, 3rd edition) for a fuller prose description.
Use this link if you want an up to date reference to the latest version of my PF tutorial slides. I update them at semi-random intervals, and definitely for each event. Upcoming events will be announced on my blog and via various other channels.
The rewritten (2017) PF tutorial slides are available here
Norsk - oppdatert 25. september 2006: foreldet og jeg linker ikke til den. Filene fins, kontakt meg via epostadressen nedenfor om du er interessert i oppdatert utgave.
A shorter talk on PF, with a slant towards the up to date (OpenBSD 4.7 and newer) features are to be found here: PF, the OpenBSD Packet Filter, originally presented at the BSD-DK annual meeting in Copenhagen, August 18, 2010 and slightly updated for a presentation at the Bergen (BSD and) Linux User Group meeting in Bergen, January 27, 2011.
Translated versions: The tutorial has been translated into various languages at various times, mainly based on the 'long html' version. If you want to do a translation, I strongly recommend that you grab the source archive and translate the SGML source instead, then build the various formats the same way I do. If you do it that way and tell me about your work, I will assist you in any way I can and link to your translated version from here.
The new, improved The Book of PF, 3rd edition is coming as soon as we can make it happen, with ebook versions shipping and physical copies estimated to be available by early October 2014. Some parts of the book will be a bit familiar, others less so -- and the samples it contains are in both new (OpenBSD 4.7 and newer) and old (OpenBSD 4.6 and earlier) syntax where relevant, and covers both legacy ALTQ traffic shaping and the new traffic shaping system introduced in OpenBSD 5.5.
I revise and update the tutorial frequently, and I always do some sort of refresh for conferences and other appearances. The results will appear here, BSD-licensed, afterwards.

(*) News flash: On June 18th, 2014, the tutorial saw its two hundred thousandth unique visitor (as in unique host name or IP address) since moving to the new location during EuroBSDCon 2006.
