Need to review my settings

I’m using a 4g router TP-LINK MR200
and my ip in my country is dynamic ip

i need to use cloudflare to setup allowed websites and applications to be used to all users of my router

i had modified the DHCP settings in my router as attached

also i had created allow role for allowed sites
and block role to site not in the allowed sites

but unfortunatly filtering is not functional and i could access any website or application

what extra settings i need to review??
