Introduction
D-Link Services Routers oer 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 oer
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 Services Router you are able to experience a diverse set of benets:
• 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 trac without disconnecting when a landline
connection is lost. The Outbound Load Balancing feature adjusts outgoing trac across two
WAN interfaces and optimizes the system performance resulting in high availability. The
solution supports conguring a port as a dedicated DMZ port allowing you to isolate servers
from your LAN.
Note: The DSR-150/150N/250/250N products have a single WAN interface, and thus do not support
Auto Failover or Load Balancing scenarios.
• Superior Wireless Performance
Designed to deliver superior wireless performance, the DSR-500N and DSR-1000N include
802.11 a/b/g/n support, 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.
Note: The DSR-150N, DSR-250N, and DSR-500N support 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 oers an additional secure data connection for networks
that provide critical services. The DSR-1000N can be congured 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
oces with a secure link to your network. The DSR-150/150N/250/250N, DSR-500/500N and
DSR-1000/1000N are capable of simultaneously managing 5, 5, 10, 20 Secure Sockets Layer
(SSL) VPN tunnels respectively, 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
oce connectivity through encrypted virtual links. The DSR-150/150N, DSR-250/250N, DSR-
500/500N, and DSR-1000/1000N support 10, 25, 35 and 75 simultaneous IPsec VPN tunnels
respectively.
