Are you using ProtonVPN for Port forwarding a nextcloud container?

Hello world, and thank you all for your contributions to a this amazing ecosystem.

I am planning to setup Nextcloud in a Docker container on a bare metal linux mint 22 desktop. I have ProtonVPN and want to port forward the Nextcloud container using this. Please let me know if you have done this and how you did it and any guides you followed. I’ve seen some info from the following:

https://protonvpn.com/support/port-forwarding-manual-setup/
https://code.mendhak.com/run-docker-through-vpn-container/

Desktop version: Linux Mint 20.3 Cinnamon
Docker -v: Not installed yet
Nextcloud -v: Not installed yet

Please let me know if you need any further info, I haven’t downloaded Docker or Nextcloud software yet until we know what is best, hence I do not have versions of these. Thank you & much love!
