Hi again Franky,

First meat!!
----
SEE:
[Linux Magazine | DEPARTMENTS | BEST DEFENSE] (Paul Russell's)
(My preferred one!!)
http://www.linux-mag.com/depts/bestdefense.html

ALSO see, the embedded on above article, from [Linux Magazine] (also):
(A very detailed REF)
[ipchains: Packet Filtering for Linux 2.2] (Paul Russell's also)
http://www.linux-mag.com/1999-05/bestdefense_01.html
----
Then explanations!!
----
I will cross post to [suse-security] (suse-security@xxxxxxxx) also, because i
think there is much better the focal point for your query!! =:`)

ANYWAY, also because it's a much interesting question (this of FireWalling), to me
and the general audience.

Look there also for possible answers, it's very complete.

I'm not much literate on Kernel ipchains, BUT one thing i know for sure is that on
the (it will be, hope soon!!) Kernel 2.4, this will change substantially.

This is a major reason because i'm waiting it anxiously!! =8`)

It will appear the new functionality of "Netfilter" which is designed and
maintained by Paul Russell, if i'm not in mistake.

This radically changes Firewall management on Linux, and makes it much easier.

WORTH A LOOK!!

I do not answer you directly to your proposed query and SuSE 6.4 issue, but i
think it's worth drinking from sources, thought!! =:`)

HTH

Best regards,
Eduardo Carriles
