Thanks for your reply.
In the Dashboard for the duo v2 there really doesn't appear to be any access controls that go to that level of control. You can't seem to setup GROUPS, or HOSTS anywhere (even though these options appear in the dropdown menu) There's no allow guest option, nor does there appear to be any such thing as User security mode.
Here is an example of the access controls on my "Backup" share. They are swtiched to "ON", I've I set the dropdown to "USERS" but it keeps defaulting to "ALL" after a reboot. And you can see that "EVERYONE" has appeared and has read/write access. I just want to make it so only the users I specify have access.

If i select "HOSTS" or "GROUPS" - no values appear at all. Which makes these options seem rather redundant.
