Previous reply correct, VPN and 'other' such technologies create a separate layer. In order to mitigate this there are a few things you can do. Call Vodafone and put barring in place (for you, use your cellular for adult stuff) then create a non-administrative account for your child with full parental controls on the devices after removing all the VPN settings you personally do not use and uninstalling anything your child may be using to create such connections, onion, tor, openVPN, etc. That should put all the necessary controls in place to stop your child viewing mature content and make their cyber space safer for them to use. Hope this helps. Friendly neighbourhood Hacker Xer0n3.
