You should have told us that you were using Red Hat 7.3 earlier. :)
Anyway, here it goes.
1. Use "/etc/init.d/ipchains stop" as root to stop ipchains. You
now, instead of using rmmod, use "modprobe -r" just in case the
ipchains module is still loaded.
2. Delete the file /etc/sysconfig/ipchains or move it to another
folder. Red Hat's default behavior is to load ipchains, if that
file exists and contains ipchains configuration,when you start
your computer.
There you go. Now use iptables. From there, you'll just have to convert
those ipchains rule to their iptables equivalent
If you want to save your iptables config, type this on the commandline:
iptables-save>/etc/sysconfig/iptables
Like ipchains, if Red Hat finds /etc/sysconfig/iptables on start-up, it
will load iptables with the configuration stored on that file.
