I’ll ask this question because it might be something you didn’t think of.

What happens to your network connection if the VPN fails? will it continue to connect without a VPN?

I had a similar case of that happening, and ended up causing me to get some shame mail from my ISP.

now I run my VPN inside docker, and any containers that need access to it are configured as network slaves to it. VPN goes down? container reboots, all the others reboot after connection is restored, but will have no connection while it’s down.

it’s all in a well designed system of healthchecks and container configuration.
