There is a user on my (home) network that keeps on exceeding their authority. Their latest ploy is to use the Betternet VPN.
Does anyone know if - and, if so,how, I can block this VPN on my router without blocking other things. (ie I'd prefer a default allow approach)
(Working at the command prompt is not a problem, I'm very familiar with Linux and iptables). What I am struggling with is to find the ports / IP's / protocols it uses. I would prefer not to block everything except http[s] for this user.
If there is a partial option - like blocking UDP but not TCP, that would be of interest as well, as would any hacks to make it harder for this user (I do not believe they have a good understanding of networking, and a friend helped them set this up)
