This doesn’t seem to use containers, I’m running Unraid in my home network so I’d prefer a solution which uses docker. Unraid doesn’t act well on installed software.

Lovely! Will read through it if I can find a better solution than what I got suggested earlier.

Unfortunately my router doesn‘t allow filtering based on the origin IP. So I‘d have to set this up within every Docker container itself which I don‘t know how to do and I don’t know the implications of this.
