Ever since this ACTA push-up the things are starting to heat up around torrents and privacy. I am using Tribler now, but this is not secure enough for me. Not enough privacy.

I've been using in the past a swedish VPN PPTP connection. What I observed is that, when the VPN connection was down, Internet traffic wasn't cut off, rather the downloads were continuing, this time with my real IP, wearing off my protection.

1st : How to enforce a VPN connection that will cut all traffic when down? That is, the moment the connection is down, all internet traffic should cease as if I'd pull the network plug out.

2nd: Is PPTP good enough or should I ask for SSTP or IKEV2 ?

3rd: Should I disable IPv6 ? Is VPN no longer private if I keep IPv6 active?

I 'heard some stuff' about dual vpn routers to be able to improve privacy; but nothing more about how to configure one for such a task.

4th: Is there any kind of "black box" hardware equipment that can be used in hiding IP, encrypting traffic and so on ?
