I was hoping to block my LAN users from connecting to some IPs

I have installed banIP and adding some lists to the custom feeds.

Yet they are still not banning me from visiting these sites , does anybody have any idea how anybody connected to my LAN via Wi-Fi or ethernet can be blocked from using VPN lists or any of my custom lists. What are some steps I can take to ensure I am doing the correct steps. How can I ensure these IP's are Blocked on my network , I have been trying to achieve this goal for 6 months but it does not work
