If I already have a VPN always on on my system, do I need to set up a gluetun container? (lemmy.dbzer0.com)

I honestly can't get my head around this. I have a machine with Linux (endeavouros), and docker with a few containers. Since I want all the traffic from this system to go through the VPN, do I need to set up gluetun? I think not, but I am not 100% sure...

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.

I simply enable the killswitch in mullvad settings and get all the Linux isos I need. But I'm thinking to keep gluetun enabled since I've already configured it

I would recommend it. Speaking from personal experience, I trusted my VPN connection to remain on and self-heal. Thinking that cost me a strike against my ISP.

Now I know for a fact that if anything goes wrong with the VPN connection, all the containers that need it will need to restart before they have connectivity again and that can only happen after the VPN container restarts and passes healthcheck.
