→Firewall rules update
# You will need to update the firewall on '''host''' to allow <u>incoming</u> connections to '''port 53 for both UDP and TCP''' (i.e. the protocol and port that DNS uses).
# After you have updated your firewall, save your iptables rules.
# <b>Once you rules are saved, restart libvirtd to ensure NAT and forwarding rules are re-added.</b>
'''NOTE:''' You could just disable the firewall '''but that is a poor workaround!''' You are expected to be able to handle configuration (such as this) at this point in this course.
