3. Click the Edit button.
4. Go to the Permissions tab.
5. Select one of the following from the drop-down menu:

   • Local users: Assign permissions for local users (including guest).
   • Local groups: Assign permissions for local groups.
6. Customize the access permissions for each user or group by ticking or unticking the corresponding checkboxes:
   • No access: The user or group cannot access the files or sub-folders in the Hybrid Share folder.
   • Read/Write: The user or group can access and make changes to the files and sub-folders in the Hybrid Share folder.
   • Read only: The user or group can access the files and sub-folders in the Hybrid Share folder.

5. Do any of the following in the Permission Editor window to edit ACL permissions:
   • User or group: Specify the user or group whose permissions you want to customize.
   • Inherit from: This field is for viewing only and cannot be modified. You can check if the permission is inherited (from a parent folder) or explicit (shown as None).
   • Type: Select Allow or Deny to grant or deny the permission to the user or group.
   • Apply to: If you are creating a permission entry for a folder, tick the checkboxes to apply the entry to This folder, the folders (Child folders) or files (Child files) in this folder, or all files and folders contained in this folder (All descendants).
   • Permission: Tick the checkboxes of the permissions you want to apply.
     • Administration: Tick Change permissions or Take ownership to specify the user or group's access permission settings for the entry.
     • Read or Write: Tick the checkboxes in these sections to modify the user or group's permission settings for the file or folder.
6. Click Done to finish.

Manage Advanced Permissions

You can further fine-tune the access permissions of a mounted folder in the Advanced Permissions tab.

To edit advanced settings:

If needed, you can place further restrictions on users when they access a mounted Hybrid Share folder via File Station, FTP, or WebDAV. Check one or more of the following options and then click Save.

• Disable directory browsing: This prevents users from viewing the contents of the Hybrid Share folder.
• Disable modification of existing files: This prevents users from moving, deleting, or modifying files; however, users can still view, download/upload, copy, or unzip the contents of the Hybrid Share folder.
• Disable file downloading: This prevents users from downloading the contents of the Hybrid Share folder.

To edit advanced share permissions:

When enabled, users and groups can view or modify the contents of a Hybrid Share folder only if they have been granted both advanced share permissions and Windows ACL permissions.

1. Go to the Advanced Permissions tab.
2. Tick the Enable advanced share permissions checkbox.
3. Click Advanced Share Permissions to modify the advanced share permissions.

Assign NFS Permissions

You can assign NFS permissions to a mounted folder and allow Linux clients to access it.

To assign NFS permissions:

1. Go to Control Panel > Shared Folder.
2. Select the mounted Hybrid Share folder you want to edit.
3. Click the Edit button.
4. Go to the NFS Permissions tab.
5. Click Create to add an NFS rule.
6. Enter or select the required information in the popup that appears:
   • Hostname or IP: Specify the NFS client that will access the Hybrid Share folder.
   • Privilege: Select read/write permissions for the NFS client.
   • Squash: Select an access privilege to apply to NFS users.
     • No mapping maintains the original access privilege for All NFS client users (including root users).
     • Map root to admin applies the access privileges of admin users on your system to NFS client root users.
     • Map root to guest applies the access privileges of guest users on your system to NFS client root users.
     • Map all users to admin applies the access privileges of admin users on your system to all NFS client users.
     • Map all users to guest applies the access privileges of guest users on your system to all NFS client users.
   • Security: Specify which security flavor to implement.
     • AUTH_SYS checks for access permissions via the NFS client’s user identifier (UID) and group identifier (GID).
     • Kerberos authentication performs Kerberos authentication when the NFS client connects to the Hybrid Share folder.
     • Kerberos integrity performs Kerberos authentication and ensures the integrity of packets during data transfer.
     • Kerberos privacy performs Kerberos authentication and encrypts the NFS packets during data transfer. This can prevent malicious parties from tampering with NFS traffic.
7. If needed, you can select one or more of the following options.
   • Enable asynchronous: This allows your Synology NAS to reply to requests from NFS clients before any changes to files are completed and yields better performance.
   • Allow connections from non-privileged ports (ports higher than 1024): This allows NFS clients to use non-privileged ports when connecting to Synology NAS.
   • Allow users to access mounted sub-folders: This allows NFS clients to access mounted sub-folders.
8. Click Save.
