CHAPTER 1
INTRODUCTION TO DRO-250i
1.1 Overview
Nowadays LAN, WAN and Internet connectivity are becoming the
common currency for business. Intranets and Internet are carrying a
growing percentage of business transactions for data & voice
communication. For SOHO businesses and enterprise branch offices
interconnecting the company, Intranet and Internet is becoming a
competitive necessity. Such enterprise businesses also require solutions
that provide reliable, secure and high-performance access to their private
WANs and the Internet with flexibility to upgrade to new services easily
in the near future. Service providers are interested in meeting this demand
for new network services to capitalize on opportunities with the growing
SOHO & enterprise market.
D-Link’s DRO-250i Router is designed for small and medium enterprises.
It has 1 LAN port and 4 WAN ports.
The supported WAN Ports are:

Introduction to DRO-250i
Load balancing
User can connect to multiple WAN networks and the load can be
distributed to between these multiple WAN interfaces to get good
bandwidth. If any interface goes down the traffic will be diverted back to
the connected interfaces.
Firewall
The DRO-250i also includes a firewall which has the following features:
• Access Policies
• Network Address Translation (NAT/NAPT) with Popular ALG
Support.
• Inbound and Outbound policies for all the interfaces.
• Intrusion detection system (IDS)
• Denial of Service (DoS) and Distributed Denial of Service (DDoS)
• Filter like IP address, port, domain name, Mac address, URL etc.,
• Virtual servers
• Port forwarding
VPN
Using the DRO-250i integrated VPN, you can provide a secure connection
between widely separated office networks or securely link telecommuters
or travellers to the office network. An encrypted traffic tunnel is created
between DRO-250i protected networks or between a DRO-250i and third
party VPN products that support IPSec.
NAT
When a TCP or UDP packet is received by the Router the IP address in
this packet will be translated between the WAN and LAN side of the
Router if this option is enabled. DRO-250i supports all the combinations
of NAT models like Many to Many, Many to One, One to Many, One to
One

device through any SNMP manager. This feature allows network
administrators to manage network performance, find and solve network
problems, and plan for network growth.
Multicasting
Internet Protocol (IP) multicast is a bandwidth-conserving technology that
reduces traffic by simultaneously delivering a single stream of information
to thousands of corporate recipients and homes. Applications that take
advantage of multicast include videoconferencing, corporate
communications, distance learning, and distribution of software, stock
quotes, and news. DRO-250i routers are enabled with Protocol
Independent Multicast (PIM) and other supporting multicast protocols like

CONFIGURATION THROUGH WEB
The Web configuration is simple and easy to use. It will help in quick
setting of the Router to connect to ISP (Internet Service Provider) with
few steps required. It will guide user step by step to configure the
password and WAN settings of DRO-250i.
3.2 INTERFACES
3.2.1
INTERFACES-LAN
The LAN Settings allows user to view the current IP address and subnet
mask assigned to the Router. It also allows user to change these settings.
If it is necessary to change the IP address or subnet mask assigned to the
Router, enter the new values in the appropriate fields and then click apply
to make the current changes.
For an example, if LAN network is to be a 192.168.0.x network with a
subnet mask of 255.255.255.0, user might assign the Router an IP address
of 192.168.0.1 and configure its DHCP server to assign addresses in the
range between 192.168.0.2 to 192.168.0.100. The default gateway setting
for computers on the LAN side will be the DRO-250i’s IP address which
in this case is 192.168.0.1.
Saving all of this information to the DRO-250i's flash and restarting it will
make this IP addressing scheme current. In Windows, when the user
enables DHCP on the NIC he/she will obtain an IP address automatically,
upon restarting the computer(s) connected on the LAN side of the Router.
User’s computer(s) will automatically be assigned an IP address (es) from
the range 192.168.0.2 to 192.168.0.100. As an alternative, user could
disable the DHCP server and manually update the IP address, subnet mask
and default gateway information for each computer on the LAN side.
DRO-250i User Manual
20
Introduction to DRO-250i
It is recommended that if user needs to change the IP addressing scheme
for the Router, he/she can configure its DHCP server with the appropriate
IP address range an d subnet mask, and then assign an IP addres s from the
same range. This way, a computer on the LAN side of network can always
get the proper network addressing information by DHCP from the Router
simply by being restarted.
