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-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, 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 t o p ro v id e h igh d ata rates with min imal “d ead
s p o ts ” t h ro ug h o u t th e wireles s co v erag e 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 Lay er 2 Tunneling
Protocol (L2TP) to facilitate branch office 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.
Efficient D-Link Green Technology
As a concerned member of the global community, D-Link is devoted to
providing eco-friendly products. D-Link Green WiFi and D-Link Green
Ethernet save power and prevent waste. The D-Link Green WLAN scheduler
reduces wireless power automatically during off-peak hours. Likewise the D-
Link Green Ethernet program adjusts power usage based on the detected cable

LAN Setup
It is assumed that the user has a machine for management connected to the LAN to the
router. The LAN connection may be through the wired Ethernet ports available on the
router, or once the initial setup is complete, the DSR may also be managed through its
wireless interface as it is bridged with the LAN. A c ces s th e ro uter’s graphical user
interface (GUI) for management by using any web browser, such as Microsoft Internet
Explorer or Mozilla Firefox:
Go to http://192.168.10.1 (d e fault IP ad d res s ) to d is p la y t h e ro u t er’s
management login screen.
Default login credentials for the management GUI:
Username: admin
Password: admin
If th e ro u t e r’s LA N IP add res s was ch a ng ed, us e that IP address in the navigation
bar of the browser to access the router’s managemen t UI.
2.1 LAN Configuration
Setup > Network Settings > LAN Configuration
By default, the router functions as a Dynamic Host Configuration Protocol (DHCP)
server to the hosts on the WLAN or LAN network. With DHCP, PCs and other LAN
devices can be assigned IP addresses as well as addresses for DNS servers, Windows
Internet Name Service (WINS) servers, and the default gateway. With the DHCP
server enabled t h e ro u t er’s IP add res s s erv es a s t h e g at eway addres s for LAN and
WLAN clients . The PCs in the LAN are assigned IP addresses from a pool of
addresses specified in this procedure. Each pool address is tested before it is assigned
to avoid duplicate address es on the LAN.
For most applications the default DHCP and TCP/IP settings are satisfactory. If you
want another PC on your network to be the DHCP server or if you are manually
configuring the network settings of all of your PCs, s et t h e DHCP mode t o ‘n o ne’.
DHCP relay can be used to forward DHCP lease information from another LAN
d evice that is th e netwo rk’s DHCP s erv e r; this is p a rticularly u s efu l fo r wireles s
clients.
Instead of using a DNS server, you can use a Windows Internet Naming Service
(WINS) server. A WINS server is the equivalent of a DNS server but uses the
NetBIOS protocol to resolve hostnames. The router includes the WINS server IP
address in the DHCP configuration when acknowledging a DHCP request from a
DHCP client.
You can also enable DNS proxy for the LAN. When this is enabled the router then as
a p ro xy fo r all DNS re q u es ts and communicat e s with th e ISP’s DNS s erv e rs . W hen
disabled all DHCP clients receive the DNS IP addresses of the ISP.

To configure LAN Connectivity, please follow the steps below:
1. In the LAN Setup page,enter the following information for your router:
IP address (factory default: 192.168.10.1).
If you change the IP address and click Save Settings, the GUI will not respond.
Open a new connection to the new IP address and log in again. Be sure the LAN
host (the machine used to manage the router) has obtained IP address from newly
assigned pool (o r h as a s tatic IP ad d res s in the ro ut er’s LAN s u bn et) before
accessing the router via changed IP address.
Subnet mask (factory default: 255.255.255.0).
2. In the DHCP section,select the DHCP mode:
No n e: t h e rou t er’s DHCP s erv er is d is a b le d fo r the LA N
DHCP Server. With this option the router assigns an IP address within the
specified range plus additional specified information to any LAN device
that requests DHCP served addresses .
DHCP Relay: With this option enabled, DHCP clients on the LAN can
receive IP address leases and corresponding information from a DHCP
server on a different subnet. Specify the Relay Gateway, and when LAN
clients make a DHCP request it will be passed along to the server
accessible via the Relay Gateway IP address.
If DHCP is being enabled, enter the following DHCP server parameters:
Starting and Ending IP Addresses: Enter the first and last continuous
addresses in the IP address pool. Any new DHCP client joining the LAN is
assigned an IP address in this range. The defau lt starting address is
192.168.10.2. The default ending address is 192.168.10.100. These
addresses should be in the same IP address subn et a s t h e ro u ter’s LA N IP
address. You may wish to save part of the subnet range for devices with
statically assigned IP addresses in the LAN.
Primary and Secondary DNS servers: If configured domain name system
(DNS) servers are available on the LAN enter their IP addresses here.
WINS Server (optional): Enter the IP address for the WINS server or, if
present in your network, the Windows NetBios server.

Lease Time: Enter the time, in hours, for which IP addresses are leased to
clients.
Relay Gateway: Enter the gateway address. This is the only configuration
parameter required in this section when DHCP Relay is selected as its
DHCP mode
3. In the DNS Host Name Mapping section:
Host Name: Provide a valid host name
IP address: Provide the IP address of the host n ame,
4. In the LAN proxy section:
Enable DNS Proxy: To enable the router to act as a proxy for all DNS
req u es ts and co mmu n icate wit h th e ISP’s DNS s erv e rs , click th e checkb ox.
5. Click Save Settings to apply all changes.

2.1.1 LAN DHCP Reserved IPs
Setup > Network Settings > LAN DHCP Reserved IPs
This router DHCP server can assign TCP/IP configurations to computers in the LAN
explicitly by adding client's network interface hardware address and the IP address to
be assigned to that client in DHCP server's database. Whenever DHCP server receives
a request from client, hardware address of that client is compared with the hardware
address list present in the database, if an IP address is already assigned to that
computer or device in the database , the customized IP address is configured
otherwise an IP address is assigned to the client automatically from the DHCP pool.
Computer Name: The user defined name for the LAN host.
IP Addresses: The LAN IP address of a host that is reserved by the DHCP server.
MAC Addresses: The MAC address that will be assigned the rese rved IP address
when it is on the LAN.
Associate with IP/MAC Binding: When the user enables this option the Computer
Name, IP and MAC addresses are associated with the IP/MAC binding.
The actions that can be taken on list of reserved IP addresses are:
Select: Selects all the reserved IP addresses in the list.
Edit: Opens the LAN DHCP Reserved IP Configuration page to edit the selected
binding rule.
Delete: Deletes the selected IP address reservation(s)
Add: Opens the LAN DHCP Reserved IP Configuration page to add a new binding
rule.

Advanced > IPv6 > IPv6 LAN > IPv6 LAN Config
(1) In IPv6 mode, the LAN DHCP server is enabled by default (similar to IPv4
mode). The DHCPv6 server will serve IPv6 addresses from configured address
pools with the IPv6 Prefix Length assigned to the LAN.
IPv4 / IPv6 mode must be enabled in the Advanced > IPv6 > IP mode to enable
IPv6 configuration options.
LAN Settings
The default IPv6 LAN address for the router is fec0::1. You can change this 128 bit
IPv6 address based on your network requirements. The other field that defines the
LAN settings for the router is the prefix length. The IPv6 network (subnet) is
identified by the initial bits of the address called the prefix. By default this is 64
bits long. All hosts in the network have common initial bits for their IPv6 address;
th e nu mb er o f co mmon in it ial bits in t h e n etwo rk’s ad d res s es is s e t b y t h e p refix
length field.
