Unified Services Router


The D-Link® DSR-250 Unified Services 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.

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-250 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-250 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 reduce 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.

Business Benefits

"The support from D-Link was excellent. When you’re rolling out something like this and buying a large quantity, support is one of the things you take into consideration. I had had prior exposure to D-Link and I felt comfortable that this would be the perfect fit for the museum and it was."
