D-LINK DSR-250 A2 DSR Series Unified Services Routers DSR-250/E

DSR-250 A2 DSR Series Unified Services Routers

The D-Link DSR Series Unified Services Routers provide secure, high-performance networking solutions to address the growing needs of small and medium businesses. With integrated highspeed wireless1 technology, the DSR series routers offer comparable performance to wired networks, but with fewer limitations. Next generation wireless performance is available on the DSR-500AC and DSR-1000AC, which introduces 802.11ac support to the family. Available on the 5 GHz band, the combination of wider Radio Frequency bandwidths take data rates available to clients supporting the wireless AC standard to the next level.

Comprehensive Management Capabilities

The DSR-500/500AC and DSR-1000/1000AC Unified Services Routers include dual WAN Gigabit Ethernet ports to provide high availability for your WAN or Internet connections. Traffic can be load-balanced across the links with Outbound Load Balancing, increasing the performance and availability of business applications. The secondary WAN port can also be used to create a DMZ, isolating servers from your LAN. The DSR series supports mobile broadband networks via an extendable USB modem4, such as 3G or 4G8 dongles. Traffic load balancing can be performed on the mobile data connections, providing an additional layer of redundancy for critical or backup applications.

Web Authentication Capabilities

Captive Portal allows employees and guest users to be easily authenticated and authorized by accessing a customized landing page. Users can be authenticated by a local database, RADIUS, LDAP, Microsoft Windows Active Directory, NT Domain and POP3 server. A maximum of four servers can be configured at any one time.

Complete and 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 series routers are capable of Secure Sockets Layer (SSL) VPN tunnels, as well as Generic Routing Encapsulation (GRE) tunnels, empowering your mobile users by providing remote access to a central corporate database. 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. OpenVPN allows mobile users to connect to the intranet via encrypted links with their PC, laptops or mobile devices.

Web Content Filtering

The DSR series also provides a web content filtering feature to help administrators monitor, manage and control employees’ Internet usage. Static web content filtering helps to remove malicious objects such as Java applets, ActiveX, and cookies, or to block URLs by keyword. Dynamic web content  filtering, which requires a license subscription, allows administrators to filter content from a list of categories. Multiple global index servers, with millions of URLs and real-time website data, enhance performance and maximize service availability.
