Sorry to nitpick, but the tutorial actually moved some time ago. There was simply too much troubles with hosting, so I finally got a domain of my own (frozentux.net), and the tutorial is available at http://iptables-tutorial.frozentux.net, hosted by haringstad.com which looks really really good so far. Of course, if they would go down, i will always be able to move the DNS to somewhere else in the future instead... Anyways, just to let everyone know. I got some other things under development as well right now, hence the iptables stuff is pretty much at a "featurefreeze".
