Thanks, that's not what I want. Putting the hole server on the internet is easy. The server gets an Ipv6. I want to use nextcloud and of course I need access from outside to connect my phone to the nextcloud docker. So I only want that docker on the internet. If that's a huge security issue, then nextcloud is worthless. Same with OpenVPN as an example. The container must be reachable from the outside to connect to. I thought the container is by design not able to talk to the host. For security reasons. If I had a public Ipv4 it would be easy to open a port for the Nextcloud docker, but I only have a public Ipv6 and the container don't get an Ipv6. So, where I am wrong?
