KISS Firewall // How to block 123.456.***.*** range?

[hoobastank68]

Hi,

I currently have a user who keeps signing up using fraud paypal accounts and we tried blocking his ip which we did so by using KISS Firewall and put in below so it blocks 123.456.78.* Range

123.456.78.0/24

Now the user is using other ips such as 123.456.51.31

How can we block lets say
123.456.*.* in KISS Firewall? Thank you.

You're wanting to block an entire Class B network.

A class B network can be defined as the first two octets, followed by .0.0, followed by /16.
