Thanks, guest network is great solution for, well, guests, but sometimes (at least once for me in one month) there are guys who bruteforce wifi key. 

While I received the notification for that one and banned the guy from the internet, it would be beneficial if I was sure that the guy would not use LAN resources (even if used internet), so I am a bit more relaxed about such bruteforce guys.

[How to set up "No access to USB storage for unregistered devices"?]

I wanted to allow usage of local network and USB drives in particular only to devices I know, to registered ones.

So that guests can go to the internet through my WiFi, but not to USB drives.

Could you please advise how and what should I configure?
