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-500N 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.
Superior Wireless Performance
Designed to deliver superior wireless performance, the DSR-500N and DSR-
1000N 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.
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-500, DSR-
500N, DSR-1000 and DSR-1000N are capable of simultaneously managing 10
or 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
office connectivity through encrypted virtual links. The DSR-500 / 500N
supports up to 35 simultaneous VPN tunnels, and the DSR-1000 / 100N up to
70 VPN tunnels.
