I have now tried a minimum firewall setup from the Iptables tutorial from
 www.iptables.org
 (http://www.iptables.org/documentation/tutorials/blueflux/).

It works!!!

I have tried to disable ip_conntrack_ftp from /sbin/SuSEfirewall2 by
 commenting it out the modprobe. But the server still crashes..

I have also tried to copy all of the modprobe's from the tutorial into
 /sbin/SuSEfirewall2 - No change!

The reason why I would like to get SuSEfirewall to work is to setup a
 firewall without having to learn all about iptables - I'm a programmer not a
 sysadm and just need a setup to protect our office computers.

Does anyone now a good step by step guide: Howto setup iptables firewall with
 VPN gateway???
