Product Highlights
D-Link Unied 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 
oers 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 trac without disconnecting when a landline connection 
is lost. The Outbound Load Balancing feature adjusts outgoing trac across two WAN 
interfaces and optimizes system performance, resulting in high availability. The second 
WAN port can be congured 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.”
