D-Link Unified Services Routers are secure, high performance networking solutions that address the growing needs of small and medium businesses. The integrated high-speed IEEE 802.11n wireless technology in the DSR-150N, DSR-250N and DSR-500N routers offers comparable performance to traditional wired networks, but with fewer limitations. Each router provides optimal network security 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). These routers also allow you to empower your road warriors with clientless remote access anywhere and anytime using SSL VPN tunnels.
The DSR-500/500N include dual-WAN Gigabit Ethernet ports that provide policy-based service management to ensure 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 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.
Designed to deliver superior wireless performance, the DSR-150N, DSR-250N and DSR-500N include 802.11b/g/n support allowing for operation on the 2.4 GHz wireless LAN radio band. Multiple In Multiple Out (MIMO) technology allows the DSR-150N, DSR-250N and DSR-500N to provide high data rates and a wide wireless coverage area with minimized “dead spots.”
A full featured virtual private network (VPN) provides your mobile workers and branch offices with a secure link to your internal network. The DSR-150/150N, DSR-250/250N and DSR-500/500N are capable of simultaneously managing 1, 5 or 10 Secure Sockets Layer (SSL) VPN tunnels respectively, 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-150/150N supports up to 10 simultaneous VPN tunnels, the DSR-250/250N supports up to 25 simultaneous VPN tunnels, and the DSR-500/500N supports up to 35 VPN tunnels.
