Did you run "sysctl -p" after making the change?

Are you trying to build a router or just be able to use iptables?

Redhat 8.0 should already have iptables support in the kernel. I
don't use redhat but you should check to see that ipchains isn't

hint:
# ntsysv

Then kill ipchains if it is running.
