I've updated the Firewalling with PF manuscript, mainly for the tutorial I gave at the AUUG2005 conference. So far only the English version with slides is available. I will get the Norwegian updated as soon as possible, but presumably not until next week or so. Comments welcome as always. And yes, it's still BSD licensed.
