We'll learn how to use OPA Gatekeeper to prevent any kind of ingress/egress IP CIDR Ranges.

In this scenario, we have seen how to prevent any kind of ingress/egress access rules and the reason behind using the policies for our organization.

For more info on this scenario - Restrict Ingress IP CIDR Ranges in NetworkPolicies.
