IP filtering for shared folders (not only for whole NAS)

[jnetasustor]

Summary:
- I would like to restrict access to some shared folders by IP

Detail:
I've just been delivered AS 602T and I start discovering all its functionnalities. I guess it's not possible to restrict access to shared folders by IP.

What we can do:
- restrict access to each shared folder by user and/or by group
- restrict access to the whole NAS by IP

Why such a need:
I've got many devices on my network that are not all "safe":
- managed computer (assumed to be safe!)
- tablet, guests devices, …: assumed to be unsafe (keyloggers, virus, …)
- audio/video devices (tv, …): only need to access multimedia folders

I would like to be sure that only my managed computer can access folders that contain very sensitive information, while other devices (ex: guests, tablet) would be able to access only pictures/movies folders, …
