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…
All of that can be achieved with simple systemd or iptables/routes tweaks. You can force all outgoing traffic to use the VPN interface via routes (meaning if it doesn’t exist or doesn’t work nothing will be able to access the internet) OR use systemd globally hide the non-VPN network interface from all software except for the VPN client.
Well sure, but the question was about gluetun, so I was trying to focus on that and the applications thereof. In terms of homelab stuff, I know a lot of people appreciate the containerized approach.
What I said applies to containerized setups as well. Same logic, just managed in a slightly different way.
Fair; I blame target fixation
