I'm using a VPN and want to create a program rule that will block a program's outgoing access if the VPN goes down. I believe the way to do this would be to create a rule that blocks the program's traffic if it attempts to connect to an external computer over the default IP address but not if it attempts to connect over the VPN IP address. In Windows Firewall with Advanced Security, I am able to specify both the local and remote addresses, but with NIS, it appears that I am only able to specify the remote (destination) addres. Is there a way around this?
