IP Tables and Killswitch

[Hawkins1212]

So first, I'll apologize in advance. Somewhat of a amateur at linux and trying to understand the NordVPN Killswitch/iptables feature within the docker.

I am running Unraid but can certainly have access and ability to use console. My question is surrounding the killswitch. I have two other containers/dockers that are being routed through this nordvpn docker. I've verified it to be set up correctly using curl ifconfig.io How do I ensure that if something happens to the Nordvpn docker, that it "kills" these other two dockers? I understand this done via iptables but cannot find a good reference online with how to set this up. TIA -- Hawkins

you could stop the vpn service using
nordvpn disconnect inside the nordvpn container
then check the connection in the dependent containers
