===Confirm Default vs Updated Firewall Rules for VMs===
You should have learned in OPS235 how to view existing iptables rules with the command: iptables -L.Although you may assume that this listing of rules should be empty, they may not be! <br>There might be default rules that already exist, or that exist when the firewall is reset to default (i.e. iptables -F).
In fact, several rules were '''automatically added''' to your chains because you are using a '''virtual network'''. As an exercise, we will determine which of those rules when running a virtual network were added.
