@qdm12 is more or less the only maintainer and is having a tough time keeping up with the issues of the project, so please:
Actually on most systems, Gluetun can create the tun device just fine and there is no need to have
devices:
- /dev/net/tun:/dev/net/tun
What error do you get when not having the devices block? 🤔
I'm on OpenSUSE Tumbleweed and it's known for being a bit more "demanding" with permissions. When I checked the logs on the docker container it said it couldn't create a connection to the TUN device because it lacked permissions. (yes I added docker to my user group) After figuring out the issue when I read the logs and fixing it, later I also noticed that on the gluetun github, their docker-compose.yml also used this parameter:
devices:
- /dev/net/tun:/dev/net/tun
If I remove this, this is the log I get btw:

Mind you, this is something new. It always worked before in OpenSUSE TW without this entry:
devices:
- /dev/net/tun:/dev/net/tun
I think it was the new version of gluetun that made some changes. Or maybe some changes on OpenSUSEs end? I know someone who also uses Tumbleweed and the same happened to him. So this tells me it's not just me

What's missing?
Update all the VPNs docker-compose.yml with the tun device permission. The default docker-compose.yml files in this wiki are outdated and won't work due to missing permissions. For example for ProtonVPN would be like so:
