Since the OS/5 release; I have become confused regarding how this device communicates to the internet (WD servers or otherwise).
QUESTION 1) If I turn off the cloud services; what communication still occurs between an OS5 NAS and the outside world?
My expectation is “none”.
However; I suspect some internet communication is still required for “authentication”?
FOLLOWUP: if we require internet communication for “authentication”, is there anyway to disable that function? (Concern: this off-site authentication is almost by definition a “Man in the Middle”; and something to be avoided from a Cyber perspective)(I consider offsite authentication a show-stopper weakness of the architecture)
FOLLOWUP: Is there any other internet access required for proper functioning of the NAS within a local network
QUESTION 2) If I BLOCK WAN access to the NAS at the router/firewall level; do I lose any functionality on the NAS?
My expectation is “no”. My suspicion is “yes”.
(Note: I don’t really want to do this; as it appears that my router will also block access to contact to other subnets within the Router. This is “bad” for me; as VPN access logon is via a dedicated subnet; which is separate from the LAN devices)
NOTE: I do not want a rehash of “direct”, “Local”/“Port forwarding” and “relay connection” definition. For purposes of this discussion. . . the NAS is configured correctly and shows proper connections without “relays”.
