configure the system.It will also cover related subjects in network structures and hardware installation which
will help you during your setup of DLM-3500.
2.1 Preparation
Before you get started, there are few things you need to know:
1. The position of the DLM-3500 LAN Port: It has five network interfaces and the last port is LAN Port which
is marked on the machine.
2. The default IP address for LAN interface is 192.168.0.1
3. Your IP addresses for computers in the LAN should be changed to 192.168.0.2 (or 192.168.0.x) and
subnet mask 255.255.255.0 in order to avoid conflicts with the default LAN port.
4. Check your network environment carefully before installing DLM-3500. A well-designed network
environment with the necessary information such as your network structure, IP addresses, and network
segments information will help you complete the setup of DLM-3500 parameters.
5. DLM-3500 uses a web-based management user interface (Web-based UI). Due to internal design
constraints, you have to use Microsoft Internet Explorer 6.0 (IE 6.0), or higher to access the Web-based
UI. A screen resolution of 800x600 or higher is recommended.

2.3 DLM-3500 Web-based UI Overview
After logged in, you will be able to start configuring or monitoring DLM-3500 through the Web-based UI.
In order to help you to familiar with the basic operations, the explanations are as follows:
The Web-based UI tasks are grouped into four categories. The categories are located at the upper left-hand
corner of Web-based UI task bar. The four categories are:
System
Network
Service
Log
On the first stage,you can login as Administrator in the Web-based UI and modify the Administrator or
Monitor password by performing the following:(1)Click System and select Administration on task bar,(2)
enter your new admin password or monitor password, after the system confirmation, using the new
password next time you log in.
Password Recovery
If you forget your administrator password, use a Terminal (VT-100 compatible) to establish the connection
between PC RS-232 series port and DLM-3500 Console interface, execute system reset to default.
Before you log into serial console, please complete following setting: Bits per second: 9600, Data bits: 8,
Parity: None, Stop bits: 8, Flow control: None. The serial console and Web-based UI use the same
username and password pairs. By default, the password of “admin” is “admin”, and the password of
“monitor” is “monitor”. If the password is changed via the Web-based UI, it will also be changed in the serial
console. In case you lose your password, you can use the username “reset” and password
“DLM-3500_dlink” to log into serial console and reset the system to default.
Open the IE browser to access the Web-based UI
Please Note: Please remember the changed password; otherwise it is not possible to access the DLM-3500
management interface.

2.4.2 Network Scenario
In this section, we will walk you through a simple example to configure DLM-3500 step by step. The network
architecture in this example is illustrated as below. DLM-3500 is running outbound load-balancing on WAN 1
and WAN 2 interface with two last mile connection from ISP 1 and ISP 2. WAN 1 uses static IP address
assigned by ISP 1 and ISP 2 will use automatically IP address assigned by ISP 2.
2.4.3 Configuring Your WAN Interface
Click on the [Network] -> [WAN Setting] in menu, you will see the page for WAN setting. Before configuring
your WAN setting, make sure you know the gateway, public IPs from your ISP. Information like this should
have been given to you when first applied for a WAN connection with your ISP. They are essential to make
your WAN connection work properly.

After you see the [WAN Setting] page, the procedure for configuring WAN settings is listed below:
1. Select the number of WAN links you want to configure. If you have multiple links, you can only edit one
WAN link at a time.
2. In the [Basic Setting] table, tick the checkbox next to “Enable” to activate the WAN link.
3. Select your WAN mode in the second field. Several options are available in this dropdown list. The WAN
type depends on how your ISP allocates the WAN link to you.In this example, we assume you are given a
single public IP from your ISP, so you need to configure your WAN mode as “Standard”.
4. In the thrid and fourth field, fill in your upstream and downstream bandwidth limits of your WAN link.
5. In the fifth field, you can set it manually or system can get it automatically.
5. In this example, we assumes you have a healthy WAN and stop monitoring ICMP and TCP packets, so we
configure it as “Never”. (For further information about “WAN Link Health Detection”, please refer to
the User’s Manual)
6. Fill in your IP Address to WAN1 of DLM-3500 in the ninth field. In this example, it is 211.30.10.11
