I've tried to set up my OMV as a pure NAS. This means the only thing its running is syncthing (inside Docker which is maintained through portainer).
My router forwards no ports. I hope this means that the web interfaces (OMV, portainer and syncthing) only are accessible from LAN. Is this correct?
As far as I can see, syncthing is the only WAN-facing application and it's already encrypted. So no need for LetsEncrypt, right?
I want to set up a second machine with a Plex-container and some torrent-related containers. These will all be routed through a VPN-container.
The OMV NAS will share (probably NFS) its data with this other machine, mainly for the sake of Plex.
Am I safe now?
