Should Bind9 Name Server be run behind a firewall?

[Programming Padawan]

I have working to get a Bind9 authoritative name server running. I am using an Incus (LXC) system container (debian12) to do this in. It is apparently a base system as there are only 19 services listed when I run the 'systemctl --type=service' command.

Should I also install and configure the iptables on this system? Would this help the name server security?

I would appreciate your thoughts.

This is a really great document, don't rush it. Some ideas probably have transitioned to other solutions by now, but it's the approach to security that I really like.
