Changes

Remember that you're are supposed to have a working firewall on your '''vm1 ''' (and every other machine), but this is the one we're concerned with will focus on our vm1 machine for now). A <u>working </u> firewall will block requests to ports that you didn't explicitly allow. Which This means that at this point , your DNS server, even though it's perfetly perfectly configured, is <u>'''inaccessible '''</u> because iptables won't allow the requests to come in.

You'll will need to update the firewall on '''vm1 ''' to allow <u>incoming </u> connections in '''UDP port 53 - that's '' (i.e. the protocol and port that DNS works overuses). Then After you have updated your firewall, then save your iptables rules using whatever means worked for you in the iptables labsand add it to a shell script. 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.
