NordVPN-Connector v 0.2Function extension "Kill Switch":
To ensure that if the OpenVPN connection is interrupted, no further request can be made from or to the Internet,
I have used iptables, which only allows requests for the currently used VPN-IP address and its DNS,
For this, under Settings also "Kill Switch" must be activated.
So if no OpenVPN connection is active when the kill switch is activated, no request to the internet is possible.
Additionally fixed some bugs.
