I consider myself quite tech-savy but this one gives me real pain.
I've connected to VPN through PPTP and I'm attempting to set up firewall rules to block any application from using it. Essentially, I want this working on a white-list basis, and leave my primary local connection for general use. Local connection is listed as private network and VPN as public. So in Windows Firewall, advanced settings, I set up one rule for inbound and one for outbound connections, both using similar settings:
- all programs
- all ports & protocols
- all IP addresses
- block connection
- public profile
- from "Advanced" tab in rule editing window, I mark "remote access" interfaces.
This doesn't work - my applications can still connect through VPN. In fact, any combination of profile and interfaces settings either don't do anything, or blocks both local and VPN connection. What should I do in order to get this done?
