[Help] VPN Killswitch Rules

[bambirombi]

I have attached the settings.
The problem is that, despite I enable the rule attached, that I have seen in https://gist.github.com/Necklaces/18b68e80bf929ef99312b2d90d0cded2 it does not work. I enable the firewall and the VPN stops working. I do not have any idea of what else could I do...
