Can this be done?
1- RPi4 with a USB3 hard disk (4TB)
2- Hard disk served out by NFS or Samba
3- RPi4 located on a remote location (daughter's home)
4- RPi4 connected by WiFi on the remote network and from there onto the Internet via remote router
5- OpenVpn client on RPi4 connects automatically to home OpenVPN server via Internet
6- RPi4 now visible on the home network and can be used as file store
I have tested item #5 on an RPi4 to connect manually via terminal to a remote OpenVPN server and it does work, but AFAIK the RPi4 is in this case able to browse the remote network but is not visible itself on that network (item #6)...
The plan is to configure an RPi4 with a big disk and let it run on my daughter's network to serve as a backup storage server for backups made on my own home LAN.
This would then be an off-site location for backups in case there is a fire etc...
Can it be done and if so how should I configure the two ends?
