Block http/https traffic for multiple clients

[Garf]

Have some problems with setting up a rule to block http/https traffic for multiple clients in my company network.

The clients I want to block are all assigned static ip adresses. I have no problem with set a rule to block a single ip, but dont want to create 10 different rules.

So for exemple  I want to block the ip´s 192.168.0.140 - 147

What do I set in the network adress field? See attached image.

Thanks for any help!  :)
