We will only refer to those basic DSM OS settings you will have to deal with at least once on this page.

Control Panel

The most important icon on the desktop is that of the Control Panel because it contains DSM's settings and functions. All choices are categorized into four main categories: File Sharing, Connectivity, System, and Application. All icons are also quite self-explanatory and nicely designed. There are two modes, basic and advanced.

File Sharing - Shared Folders - Guest Account

You will have to create some folders and give permissions to them in order to give specific users or groups access. This can be done through the Control Panel's Shared Folder menu. This menu also allows you to modify access privileges for shared folders, delete them, or encrypt them with AES 256-bit encryption, which makes all unauthorized access attempts impossible.


You will have to enable the guest-user-account option if you want some of your shared folders to be accessible by guests. You can also check the permissions users have for all shared folders and change them here.

File Sharing - File Services

You must enable your client PCs' file service system here for the NAS server's shared folders to be seen by the network. You can also enable the FTP and TFTP services in the Files Services menu.

Connectivity - Network Settings

The DS916+ has two Ethernet ports and the DSM OS supports port teaming, which you can set in the Network Settings tab.


The same tab also allows you to manage and implement traffic-control rules should you wish to pre-determine which outgoing traffic is allowed when clients access services on your Synology NAS—also use these options to configure HTTPS settings or change port number(s) for DSM access.

Connectivity - Security

The Security menu will be of interest to those who store sensitive data on their Synology NAS servers. Set the logout timer, skip IP checking, improve protection against scripting attacks, and disable iFrame embedding in this menu. There is also a Firewall tab should you want to deny access to certain network ports by IP addresses. The Protection menu provides options to enhance each network interface's network security, while Auto Block can be used to block IP addresses with too many failed login attempts.
