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.
Reliable Internet Connectivity
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.
Superior Wireless Performance
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.”

Robust VPN Features
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 DSR150/150N
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.
Efficient Green Technology
As a responsible member of the global community, D-Link is devoted to providing ecofriendly
products. D-Link Green Wi-Fi and D-Link Green Ethernet features save power
and help cut energy costs. The D-Link Green WLAN Scheduler shuts down your wireless
network automatically according to a schedule you define, allowing you to turn off
your wireless network during off-peak hours, saving energy and keeping your network
secure. The D-Link Green Ethernet feature can detect the length of the cables connected
to the router and can adjust power usage accordingly to save energy automatically
without sacrificing performance. It can also detect if a link is down on a port and
automatically puts that port into a sleep mode, reducing the amount of power used. In
addition, compliance with RoHS (Restriction of Hazardous Substances) and WEEE (Waste
Electrical and Electronic Equipment) directives make D-Link Green certified devices an
environmentally responsible choice.
