→Part 1: Replacing firewalld with iptables
# Refer to ''Figure 1''. If your rules at this stage look different, stop and contact your professor for help. (Packet and byte count numbers will be unique.)
# Set iptables to start with the system: <code>systemctl enable iptables</code>
# Remove ''firewalld'' completely: <code>yum autoremove firewalld</code> '''Note:''' It may not be installed. If it says "no match" when you don't remove firewalld and both firewalls are set to start with run the systemcommand, firewalld will always start instead of iptables. This you can lead to much frustrationmove on. Make sure you remove it!
