Unified Services Router User Manual Chapter 1. Introduction D-Link Unified Services Routers offer a secure, high performance networking solution to address the growing needs of small and medium businesses. Integrated high -speed IEEE 802.11n and 3G wireless technologies offer comparable performance to traditional wired networks, but with fewer limitations. 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. With the D-Link Unified Services Router you are able to experience a diverse set of benefits:  Comprehensive Management Capabilities The DSR-500, DSR-500N, DSR-1000 and DSR-1000N include dual-WAN Gigabit Ethernet which provides policy-based service management ensuring maximum productivity for your business operations. The failover feature maintains data traffic without disconnecting when a landline connection is lost. The Outbound Load Balancing feature adjusts outgoing traffic across two WAN interfaces and optimizes the system performance resulting in high availability. The second WAN port can be configured as a DMZ port allowing you to isolate servers from your LAN.  DSR-250 /250N have a single WAN interface, and thus it does not support Auto Failover and Load Balancing scenarios.  Superior Wireless Performance Designed to deliver superior wireless performance, the DSR-500N and DSR1000N include 802.11 a/b/g/n, allowing for operation on either the 2.4 GHz or 5 GHz radio bands. Multiple In Multiple Out (MIMO) technology allows the DSR-500N and DSR-1000N to provide high data rates with minimal ―dead spots‖ throughout the wireless coverage area.  DSR-250N and DSR-500N supports the 2.4GHz radio band only.  Flexible Deployment Options The DSR-1000 / 1000N supports Third Generation (3G) Networks via an extendable USB 3G dongle. This 3G network capability offers an additional secure data connection for networks that provide critical services. The DSR 1000N can be configured to automatically switch to a 3G network whenever a physical link is lost.  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-250/250N, DSR-500/500N and DSR-1000 /1000N are capable of simultaneously managing 5, 10, 20 Secure Sockets Layer (SSL) VPN tunnels respectively, empowering your mobile users by providing remote access to a central corporate database. 10
