I am not a techie. I am just wanting to force some parentral control using OPENDNS. Opendns works fine however it is easily broken on android or windows using vpn software like ultrasurf or latern or securitykiss.
I spend some time to found that most of these technologies use port 80 and 443 which is used by most sites and if I blocked them the whole internet is blocked.
one solution that I found but I can't dare to apply is using sophos home network firewall, however this technology need a whole separate dedicated computer to control the network.
So my question is, is there is any software with password or a way on the router to block vpn connection on the whole network and not just one device?
