Allow Users or Groups to Access Shared Folders
Go to Main Menu > Control Panel > Shared Folder to allow or deny users' or groups' access to the shared
folders.
To allow users or groups to access a shared folder:
1 Select the shared folder you want to edit from the shared folders list, and click Privileges Setup to open the
settings window.
2 Click the Privilege Setup tab, and select any of the following from the drop-down menu:
 System Internal user: Anonymous FTP user. Before allowing anonymous FTP users to connect to a
shared folder, you need to allow their access to the folder first.
 Local users: Synology DiskStation users (including guest). See "Create and Edit Users" on Page 53 for
more information.
3 Tick or uncheck the following privileges to assign access privileges for the users or groups:
 Read/Write (RW): The user or group can access and make changes to the files and subfolders in the
shared folder.
 Read only (RO): The user or group can access the files and subfolders in the shared folder, but cannot
make changes to them.
 No access (NA): The user or group cannot access the files and subfolders in the shared folder.
Note: To set the access privileges to subfolders, you can use File Station. See "View or Change File or Folder
Permissions" on Page 74 for more information.
4 Click the Advanced privileges tab if you want to do any of the following:
 Disable directory browsing
 Disable modification of existing files
 Disable file downloading
5 Click OK.
Note:
 When you encounter privilege conflicts, the privilege priority is as follows: No access > Read/Write > Read only.
 When you create a new shared folder, if the access privilege of admin (or a user belonging to the administrators
group) to the folder is set as No access, then admin (or the user belonging to the administrators group) will only
be able to see the folder by going to Main Menu > Control Panel > Shared Folder.
To allow Linux clients to access a shared folder:
1 Select the shared folder you want to edit from the shared folder list, and click NFS Privileges.
2 Click Create to open the settings window.
3 Enter a Hostname or IP. You may specify a host in three ways:
 Single Host: The FQDN (fully qualified domain name) or an IP address.
 Wildcards: *,* .synology.com
 IP networks: 203.74.205.32/255.255.252.0, /24
4 Assign Privilege, assign Root Squash, or tick Enable asynchronous, and click OK.
5 Click OK.
Term Explanation
Asynchronous: NFS servers will reply to requests before the changes on the file are completed.
