I have a server with Red Hat 9.0 installed.

After I configured APF Firewall and tried to start it I got the message

Starting APF:Unable to load iptables module (ip_tables), aborting.

How do I install ip_tables?

Thanks

u need 2 compile kernel with ip_tables support. (as a loadable module)
i believe default generic kernel already has it built as a module. check if "iptables" exist in ur init startup directory. if yes run /etc/rc.d/init.d/iptables start and see wut happens.
