I haven't used narc, but it sounds like it generates a script for you
based on what you want to allow, etc?

You might need to disable the RedHat iptables/ipchains setup before
running your narc script if narc doesn't flush all the rules. 

service iptables stop
service ipchains stop
chkconfig ipchains off
chkconfig iptables off

Note that by default RedHat 8 uses ipchains, if it booted up and setup
ipchains you will need to rmmod the ipchains module and let it load
the iptables modules for narc to be happy. You can't have both
ipchains and iptables modules loaded at the same time.
