I have Zone Alarm Pro.
I have a good VPN service that I pay for monthly. The problem is that on the rare occasion that the VPN goes down, my internet will reconnect with my local connection exposing my true ISP address... I do not want this to happen.
I want to setup advanced rules that only allows my computer to access the internet with the VPN IP address so that when the VPN goes down the connection will be lost and NOT reconnect.
