Unified Services Router
Chapter 1.
D-Link 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 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-150/150N/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 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.

DSR-150N, 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-
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
