DSL-2542B

>>> DSL-2542B Basic Installation/Configuration

1.)Connect to the Router
To configure the WAN connection used by the Router it is first necessary to communicate with the Router through its management interface, which
is HTML-based and can be accessed using a web browser. The easiest way to make sure your computer has the correct IP settings is to configure
it to use the DHCP server in the Router. The next section describes how to change the IP configuration for a computer running a Windows operating
system to be a DHCP client.
1.To access the configuration utility, open a web-browser such as Internet
Explorer and enter the IP address of the router (192.168.1.1).

2.Type “admin” for the User Name and “admin” in the Password field. If
you get a Page Cannot be Displayed error, please refer to the
Troubleshooting section for assistance.

>>>Quick Setup

1.Click the Setup Wizard link in the middle of the top of the window of the
Router’s opening page to launch a series of setup windows.
*** Alternatively, you can tick the Manual Setup check box and click the
desired setting option radio button in the middle of the window. The
manual ADSL connection setup is described later in this manual.

2.OPENING WINDOW
The first window of the Setup Wizard lists the basic steps in the process.
These steps are as follows:
1. Change the Router password.
2. Configure the connection to the Internet.
3. Save the new configuration settings and reboot the system.

3.)CHANGE YOUR ROUTER PASSWORD
This window of the Setup Wizard is used to change the Router password.
D-Link recommends to help secure your network, the user change the
Current Password from the factory default “admin.” The New Password
should be between 1 and 16 alphanumeric characters. Once you have
filled out the fields in this window, including re-typing the new password in
the Confirm Password field, click the Next button to continue.
If you do not want to change the password, click the Skip button to
proceed to the next step.

4.)SELECT THE INTERNET CONNECTION TYPE
Now use the drop-down menus to select the Country, ISP Provider, and
Connection Type used for the Internet connection, and enter VPI and VCI
values if applicable. Your ISP has given this information to you—any
information that is not required for your provider will automatically be
grayed out in this window and subsequent Quick Setup windows.
The Connection Type options are 1483 Bridged IP LLC, 1483 Bridged IP
VC-Mux, 1483 Routed IP LLC, 1483 Routed IP VC-Mux, PPPoE LLC,
PPPoE VC-Mux, PPPoA LLC, and PPPoA VC-Mux.
Click the Next button when you are finished to proceed to the next Setup
Wizard window.

5.)SELECT THE INTERNET CONNECTION TYPE
If the following Setup Wizard window appears, please select the
connection type used by your ISP and then click the Next button. Most
users, however, will be sent directly to a Setup Wizard window for their
specific Internet connection type based on the information entered in the
previous Setup Wizard window.

6.)FINISH & RESTART CONFIRMATION
Finally you can confirm that the setup process is completed. If you are
satisfied that you have entered all the necessary information correctly,
click the Restart button to save the new configuration settings and restart

PPPoE/PPPoA

To configure a PPPoE or PPPoA type WAN connection, follow these
steps:
1. Type the Username and Password used for your ADSL account. A
typical User Name will be in the form “user1234@isp.co.uk.” The
Password may be assigned to you by your ISP or you may have
selected it when you set up the account with your ISP. The Service
Name field is used for the name of your Internet Service Provider.
This is optional.
2. Choose the Connection Type from the drop-down menu. This
defines both the connection protocol and encapsulation method
used for your ADSL service. The available options are PPPoE LLC,
PPPoE VC-Mux, PPPoA LLC and PPPoA VC-Mux. If you have not
been provided specific information for the Connection Type setting,
leave the default setting.
3. Leave the MTU value at the default setting unless you have
specific reasons to change this.
4. Some users will want to set an Idle Time Out. This is an age-out
value, in minutes, before the Router times out.
5. If you are instructed to change the VPI or VCI values, type in the
values assigned for your account.
6. When you are satisfied that all the WAN settings are configured
correctly, click the Apply Settings button. This will save the
settings and reboot the Router to let your changes take effect.
7. Upon restarting, the Router should automatically establish the
WAN connection. If it does not, click the Connect button at the
bottom of this window.

>>> DSL-2542B NAT, Port Triggering,DMZ Host description

NAT
To access the Network Address Translation (NAT) Setup window, click the NAT button in the Advanced Setup directory. The NAT button
appears when configuring WAN interface in PPPoA, PPPoE, MER or IPoA.
Virtual Servers
This window is used to configure virtual server. You can add, delete, and
modify virtual server on this window.
If you are setting up the virtual server, click the Add button.
You can configure the service settings on this window by clicking the
Select a Service radio button and then using the drop-down list to choose
an existing service, or by clicking the Custom Server radio button and
entering your own Application Rule in the field provided.
Click Save/Apply when you are finished with the virtual server
configuration.

Port Triggering
Some applications require that the remote parties open specific ports in
the Router’s firewall for access. Port Trigger dynamically opens the Open
Ports in the firewall when an application on the LAN initiates a TCP/UDP
connection to a remote party using Trigger Ports. The Router allows the
remote party form the WAN side to establish new connections back to the
application on the LAN side using the Open Ports.
Applications such as games, video conferencing, and other remote
access applications require that specific ports in the Router’s firewall be
opened for access by applications.
Click the Add button to configure port triggering.

You can configure the port settings on this window by clicking the Select
an application radio button and then using the drop-down list to choose
an existing application, or by clicking the Custom application radio
button and entering your own Application Rule in the field provided.
Click Save/Apply when you are finished with the port setting
configuration. The new Application Rule will appear in the Port Triggering
table.

DMZ Host
Since some applications are not compatible with NAT, the Router supports
use of a DMZ IP address for a single host on the LAN. This IP address is
not protected by NAT and will therefore be visible to agents on the Internet
with the right type of software. Keep in mind that any client PC in the DMZ
will be exposed to various types of security risks. If you use the DMZ, take
measures (such as client-based virus protection) to protect the remaining
client PCs on your LAN from possible contamination through the DMZ.
To designate a DMZ IP address, type in the IP Address of the server or
device on your LAN, and click the Save/Apply button.
