To enable WebAccess for a share, click on the sharename
from Extensions/WebAccess.
Choose your desired level of WebAccess from the

'Disable' will prevent remote access to this share through
WebAccess. This is the default setting.
'Allow Anonymous' will allow anyone to access the share.
Choose this if you want your TeraStation share and all
files on it to be freely available to everyone in the world.
'Allow All Groups/Users' will allow only people who
have an account on the TeraStation to access this share
remotely.
'Use Inherited Folder Permissions' gives each user the
same rights to folders remotely that they have locally.
