Today Oskar Andreasson has released version 1.1.0 of his iptables-tutorial package, a series of documents explaining netfilter to the layperson. He mentions quite clearly that he would appreciate it if netfilter coders/experts would "if possible, please have a closer look at the tutorial."
The tutorial can be downloaded at

Subject: [release-update] iptables tutorial 1.1.10
Date: Fri, 12 Apr 2002 14:43:41 +0200
Hi all again,
This is an early warning that version 1.1.10 is about to be released of the
iptables tutorial. Most old bugs and problems have been worked out and fixed
except for a small set of persistent problems (double hyphens being quashed into a
single one, etcetera). I have been working on them, and I hope to fix them until
version 1.1.11 of the tutorial, which will hopefully be the last version for a
few months forward, except smaller version changes which will happen if I get
bugreports or problem reports from people.
Before I say anything else, I would like to ask any netfilter coders/experts
to, if possible, please have a closer look at the tutorial. I need technical
feedback really bad. I am more or less blind to any problems within it right now,
and it would be tremendously appreciated if any of you could have a closer look
and report all/any bugs you find in it. I am sure there must be at least one
error per written line :-).
For those who do not know, I will stop writing this tutorial for a brief period
of time since I have heaps of other projects who are waiting in line to be
finished. I will continue to maintain this tutorial in the meantime, but not as
extensively, and there will most probably not be any large additions for the next
5-6 months or so.
Due to recent events where certain spam robots have harvested this site for
e-mail addresses I have chosen to write all e-mail addresses, except my own, in a
harsher to harvest form. For all those of you who have gotten directed spam
about "your site at boingworld.com...", I am sorry for any inconvenience this may
have caused and I hope you don't have any hard feelings about it. I have sent
"cease and decist" mails to these spammers since what they have done is illegal
according to local laws where I live but I suppose this will make no difference
at all, as usual. If you can find any e-mail addresses that are still not
rewritten, please send me a report about it.
The tutorial should look more or less good now imnsho. If you find any parts
that are unclear, please send me a report about it.
Have a nice day,
PS. Sorry for the cross posting, I wanted to reach all of you netfilter
developers as well. DS.
