Blocking specific websites

[Green_Pen]

Hey, I just discovered Veyon and I was wondering if you can just block specific websites with the Internet-Access-Control Addon.
Can someone tell me if this is possible?

Hi,
Although this would be useful as a temporary solution in the classroom, the best ways are to modify the host file in each computer, or to put any unwanted adresses in the black list of your firewall.
