VPN Blocking

Hi
I was reading a bit around but found only how to enable VPN vis CIS and nothing real on HOW to Block any VPN access of whatever type. Additional I would like to learn in simple words how to secure any remote access to my computer via CIS. Please I am not any real specialist, as the CIS interface is real nice and simple I hope to get here some simple instructions on how to do that. I was a bit often hacked, especially if I use MetaTrader, and needed already twice to reformate my computer and to set all again fresh up to have a working situation. Any advsie real welcomed.

Hi
Nobody ready to comment? Even the Moderators not? I Need to be sure that NO remote access (Internet or IntraNet) is possible. Please advice.
