Killswitch

Implement a killswitch

[corrad1nho]

One way to approach this is using a firewall that blocks non-VPN connections. I have created a similar project and you can see the rules I'm using in this file. The actual script (Python, too) is here.

Things to consider:

• you'll have to allow the entry-ip of the OpenVPN server, too, if the firewall / killswitch is active before making a connection attempt
• it might make sense to restore flushed rules after closing the app / the connection
• if ipv6 is not needed you can block it entirely

Thank you, you made my day!
