Comodo Firewall and VPN

It would be nice if Comodo would make it easier to block the internet traffic in case the VPN goes down (which is a very common problem). More and more people use VPN online to protect their privacy.

There is programs like VPN check (http://www.jothodesign.com/vpncheck)
which does its job, but I think it is not needed now when I use comodo firewall,
cause I have seen a guide online that shows how to block internet access when the VPN goes down.

Anyway, it would be really nice if you could “check” a box in settings “block internet if VPN goes down”
Then you would need to add the rules manually. I think a lot of people who use VPN would appreciate it.
