Not having time before I updated my box today to kernel version 2.4.22
from kernel.org. The system works still very well but I'm still not
able to unload the conntrack module. It's the same problem as I
described above using 2.4.21. So anyone there who knows an answer?
Thanks in advance.

Eicke Friedrich

In case your running an older kernel (before -pre9), try the latest -rc
kernel or submitted/70_ip-conntrack-expect-drop-refcnt-combined.patch
from patch-o-matic.

I've tried this a couple of times. The module seems to get deleted
(lsmod still shows ip_conntrack but as deleted) but rmmod does NOT
finish. It grabs 100% CPU for minutes. I had to reboot the box then.
Any hints?
Regards,
Eicke.

You could look into using the patch I send some day ago. the you could
set all connection to unconfirmed, and then set you rule set so that al
unconfirmed packets pass the rule set
