I have been tasked to implement rate-limiting measures on interfaces using IPTables in RHEL 7.

I know that in order to implement it using FirewallD, I will need to run the following command:

firewall-cmd --direct --add-rule ipv4 filter IN_public_allow 0 -p tcp -m limit --limit 25/minute --limit-burst 100 -j ACCEPT

How would I do the same using IPtables?

firewalld uses iptables under the hood. So just snoop on what rules firewalld created. Use "iptables-save > /tmp/firewalld-iptables.dump" and inspect the result.
