Installing SuSE Firewall 2

I have Suse 7.2 with standard kernel 2.4.4, and have downloaded the Suse firewall 2. I am not sure how to install it. Having expanded it from the tar ball into a directory it seems that you copy the ip-up file to /etc/ppp and clicking on install does the rest of the installation. However I am not sure it is working correctly or whether it has installed correctly. Since f/w2 uses iptables and f/w1 uses chains, I have un installed f/w1 and personal firewall. However in this state leaves me without any protection. When on line if I run iptables --list from a terminal brings up a load of errors instead of what should be expected. Can someone put me on the right road please (basic instructions appreciated) Regards, David
