I need a solution
There are several different places (forums, documentation) that state it is possible to utilize CIDR notation for setting criteria based on entire IP ranges, which is great to reduce the need for converting to numeric IPs to define ranges in rules and filters. What I am unclear on is the proper syntax for doing it. My experiments thus far do not appear to be working, as the IP's that I define still manage to slip through. See screenshot for an example, and let me know which operator I should be using and/or what the limitations are for where and when it can be used properly, thank you.
