Aprašymas

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 high-speed wireless technology, the DSR series routers offer comparable performance to wired networks, but with fewer limitations.
 
Comprehensive Management Capabilities
The DSR series supports mobile broadband networks via an extendable USB modem*, such as 3G or 4G** 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 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. 
 
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.
