Wireless N Unified Service Router

The D-Link Wireless N Unified Service Router is a cost-effective, high performance solution for securing a small business network. Optimal network security is provided via features such as virtual private network (VPN) tunnels, IP Security (IPSec), Point-to-Point Tunneling Protocol (PPTP), Layer 2 Tunneling Protocol (L2TP), and Secure Sockets Layer (SSL). Empower your road warriors with clientless remote access anywhere and anytime using SSL VPN tunnels.

Superior Wireless Performance
Designed to deliver superior wireless performance, the DSR-250N includes 802.11 b/g/n, allowing for operation on the 2.4 GHz radio band. Multiple In Multiple Out (MIMO) technology allows the DSR-250N to provide high data rates with minimal “dead spots” throughout the wireless coverage area.

Robust VPN Features
A fully featured virtual private network (VPN) provides your mobile workers and branch offices with a secure link to your network. The DSR-250N is capable of simultaneously managing 5 Secure Sockets Layer (SSL) VPN tunnels, empowering your mobile users by providing remote access to a central corporate network. Site-to-site VPN tunnels use IP Security (IPSec) Protocol, Point-to-Point Tunneling Protocol (PPTP), or Layer 2 Tunneling Protocol (L2TP) to facilitate branch office connectivity through encrypted virtual links. The DSR-250N supports up to 25 simultaneous VPN tunnels.

Efficient Green Technology
As a concerned member of the global community, D-Link is devoted to providing eco-friendly products. D-Link Green Wi-Fi and D-Link Green Ethernet save power and help cut energy costs. The D-Link Green Ethernet program adjusts power usage based on the detected cable length and link status. In addition, compliance with RoHS (Restriction of Hazardous Substances) and WEEE (Waste Electrical and Electronic Equipment) directives make D-Link Green certified devices the environmentally responsible choice.
