Retired_Member,
Welcome to the community! :)
The Policy you have specified is "Allow" which is why the devices on the 192.168.1.0 range are allowed. Kindly try to change the Policy to "Deny."
As reference guide, kindly access and read the article below:

Thanks for the reply, I don't know why it says 'Allow' in the UI but it is in fact in the policy 'Deny', when I edit an entry in the 'Deny' policy it always shows 'Allow' for unknown reasons. Denying access without defining a subnet mask works, only when defining a subnet mask I encounter this problem.
