Hi there

my clever little son has worked out how to get around the features of the Deco that restrict his access. 

I think he is doing this with a VPN, but also somehow seems to be able to remove his devices from the parental controls. 

So, my questions are:

1 how do I block VPNs from my network, and if this feature is not available it should be?

2 how do I stop a new device from connect, if I change the password all smart devices in the house need to be reconnected and that is a nightmare? I should be able to approve a new device. 

3 any ideas how he is removing himself from his group?

Thanks

Andrew
