Iptables-tutorial

The aim of the iptables-tutorial is to explain iptables in a complete and simple way. The iptables-tutorial is currently rather stable, and contains information on all the currently available matches and targets (in kernel), as well as a couple of complete example scripts and explanations. It contains a complete section on iptables syntax, as well as other interesting commands such as iptables-save and iptables-restore.

The tutorial was under heavy scrutiny and updating, as can be seen in the latest version of the tutorial. It was available in bookform from Lulu.com for a brief period of time. However due to too much technical problems and the time it took to correct all the “errors” according to Lulu, I decided it simply wasn’t worth it at the time (this might change at some point, but not likely). For example, I had a conversion error between different types of points leading to my pages being 0.03 inches too small on the height and 0.01 inches too small on the width, and because of that they refused to handle. Their way of handling this was to allow the book to be published, and then every once in a while when someone ordered a book (and paid for it), they all of a sudden cancelled the publication, sent me a note that they did so (not explaining why), and so forth. It took me 1-2 months of contact with their customer support to drag this simple “why” out of them, then another few weeks to actually find the reason for the problem. Then there was problems with the size of the cover (generated in their own webtools), etc.

If you need help, you are better off by asking the netfilter mailing list which you can reach at netfilter at lists.netfilter.org. For more information on this, visit the netfilter mailinglist page. You may also contact the linuxsecurity mailing list at security-discuss AT linuxsecurity dotcom. Both are fairly large, and should be able to help you much much better than I can.
