In a RHEL training document, the author says:
...run the following command to disable the firewall on the current system: iptables -F
He explicitly uses the word "disable" which to me suggests that it will be simple to re-enable. In reading the man page though for iptables, I see this:
Flush the selected chain (all the chains in the table if none is given). This is equivalent to deleting all the rules one by one.
Can I get clarification on the expected behavior?
