Network Management

On exploring a more stable, efficient, and versatile Synology NAS, DSM provides rich network management schemes, and ensures security at the same time.


DSM contains various solutions to best satisfy your Internet or private remote network access needs.


Using Synology global cloud infrastructure and hole punching technology, QuickConnect provides a stable and efficient solution to access everything you would ever need, wherever you are, from any browsers or mobile devices. Learn more about QuickConnect White Paper.


For those who prefer to set up port-forwarding and do everything themselves, Synology provides free DDNS service with the support of both IPv4 and IPv6. Furthermore, with the integration of Let's Encrypt, connecting to your Synology NAS by HTTPS protocol with a valid Certificate is better secure and even without paying any extra fee.

  • PPPoE and VPN Client

    Simply enter your credentials from your ISP to get direct access to the Internet; or secure your communications by connecting to private network servers with VPN Client supporting PPTP, OpenVPN, and L2TP over IPSec.

  • IPv4/IPv6 Dual Stack & IPv6 Tunneling

    Besides IPv4 support, DSM services are compatible with IPv6, the next-generation Internet protocol. Further, you can integrate your Synology NAS running IPv6 services into existing IPv4 networks with IPv6 tunneling.

  • Static Route

    Administrators familiar with their network infrastructure can manually configure the optimal static route for specific services to boost routing efficiency.

Access and Resource Control

With thorough control mechanisms, DSM ensures all incoming and outgoing data transfers more secure and efficient.


DSM is secured with a profile-based IPv4/IPv6 dual stack firewall. It allows setting up multiple profiles according to different deployment scenarios or purposes.
In each profile, firewall rules can be created regarding IP/Port constraints, and users can decide on which interface these rules will take effect.

DoS Protection

DSM also provides protection against Denial-of-service attacks to ensure your private network is secure.


Each Synology NAS within the local network can act as an 802.1x supplicant and be controlled by the 802.1x authentication mechanism to prevent potential internal threats.

Traffic Control

DSM features comprehensive traffic control capabilities to allow simple but flexible, bandwidth usage limits for each application and service.

Link Aggregation

Link Aggregation allows you to tailor the behavior of your network ports in terms of network performance and reliability, unlocking potentially higher transfer speeds and providing fault tolerance for environments with heavy traffic in small/medium offices, or for advanced users with high data rate streaming requests.

DSM supports the following modes

Multi-purpose Hub

With varieties of networking add-ons and built-in modules, Synology NAS can not only be an endpoint, but also a centralized server to provide services within your networks.

VPN Server

With Synology's VPN solution, employees can easily access internal resources remotely, without breaching security protocols. Synology VPN Server is compatible with OpenVPN, PPTP, and L2TP over IPSec. Learn more

DHCP Server

DSM's built-in DHCP Server allows your Synology NAS to assign and reserve dynamic IP addresses to DHCP clients within the local network when enabled. Learn more

DNS Server

You don't want to remember a lengthy IP address? Use DNS Server to host your own domain name services, and improve namespace management within an organization at no extra cost. Learn more


RADIUS protocol provides a central way to authenticate and authorize connections on your network. Create your own server to ensure secured authentication for everyone. Learn more

Proxy Server

Synology's Proxy Server is the ideal supplement to an efficient and secured network infrastructure. It includes numerous features such as web caching, content access restriction and monitoring, pre-defined rules, and IP filtering. Learn more

SSO Server

A single sign-on (SSO) server centralizes authentication to eliminate the inefficiency of signing into each web service one by one. You will be able to log in to Synology web applications with one single DSM account. Learn more
