My son brought it to my attention that my GF's kids may be downloading movies through torrents but using a VPN to do it. The kid I know that would do it even after I told him not to has utorent installed on his laptop. Unfortunately it is a laptop his father gave to him, so good luck for me to have full control of it. I have had some weird activity on my network and suspect he has installed a VPN client to download the shit. Is it possible for me to block all VPN activity on my network? I have not fond anything to help me out yet, and since I use tomato I was hoping I can find something hidden in it to aid me.
