How can I setup my router to work with Earthlink DSL or any PPPoE
connection?
Make sure you disable or uninstall any PPPoE software such as WinPoet or Enternet
300 from your computer or you will not be able to connect to the Internet.
Step 1
Upgrade Firmware if needed.
(Please visit the D-Link tech support website at:
for the latest
firmware upgrade information.)
Step 2
Take a paperclip and perform a hard reset. With the unit on, use a paperclip
and hold down the reset button on the back of the unit for 10 seconds. Release it and
the router will recycle, the lights will blink, and then stabilize.
Step 3
After the router stabilizes, open your browser and enter 192.168.0.1 into the
address window and hit the
Enter
key. When the password dialog box appears, enter
the username
admin
and leave the password blank. Click
OK
.
If the password dialog box does not come up repeat

username
.
Step 7
Maximum Idle Time
should be set to zero. Set
MTU
to 1492, unless
specified by your ISP, and set
Autoreconnect
to
Enabled
.
Note:
If you experience problems accessing certain websites and/or email issues,
please set the MTU to a lower number such as 1472, 1452, etc. Contact your ISP for
more information and the proper MTU setting for your connection.

Step 8
Click
Apply
. When prompted, click
Continue
. Once the screen refreshes,
unplug the power to the D-Link router.
Step 9
Turn off your DSL modem for 2-3 minutes. Turn back on. Once the modem
has established a link to your ISP, plug the power back into the D-Link router. Wait
about 30 seconds and log back into the router.
Step 10
Click on the
Status
tab in the web configuration where you can view the
device info. Under
WAN
, click
Connect

Frequently Asked Questions (continued)
Can I use my D-Link Broadband Router to share my Internet
connection provided by AOL DSL Plus?
In most cases yes. AOL DSL+ may use PPPoE for authentication bypassing the
client software. If this is the case, then our routers will work with this service. Please
contact AOL if you are not sure.
To set up your router:
Step 1
Log into the web-based configuration (192.168.0.1) and configure the WAN
side to use PPPoE.
Step 2
Enter your screen name followed by @aol.com for the user name. Enter your
AOL password in the password box.
Step 3
You will have to set the MTU to 1400. AOL DSL does not allow for anything
higher than 1400.
Step 4
Apply settings.
Step 5
Recycle the power to the modem for 1 minute and then recycle power to the
router. Allow 1 to 2 minutes to connect.
If you connect to the Internet with a different internet service provider and want to use
the AOL software, you can do that without configuring the router’s firewall settings.
You need to configure the AOL software to connect using TCP/IP.
Go to
for more specific configuration information of their software.

Frequently Asked Questions (continued)
How do I open ports on my router?
To allow traffic from the internet to enter your local network, you will need to open up
ports or the router will block the request.
Step 1
Open your web browser
and enter the IP Address of
your D-Link router
(192.168.0.1). Enter username
(admin) and your password
(blank by default).
Step 2
Click on
Advanced
on
top and then click
Virtual
Server
on the left side.
Step 3
Check
Enabled
to
activate entry.
Step 4
Enter a name for your virtual server entry.
Step 5
Next to
Private IP
, enter the IP Address of the computer on your local
network that you want to allow the incoming service to.
Step 6
Choose
Protocol Type
- either TCP, UDP, or both. If you are not sure, select
both.
Step 7
Enter the port information next to
Private Port
and
Public Port
. The private
and public ports are usually the same. The public port is the port seen from the WAN
side, and the private port is the port being used by the application on the computer
within your local network.
Step 8
Enter the
Schedule
information.
Step 9
Click
Apply
and then click
Continue
.
Note:
Make sure DMZ host is disabled. If DMZ is enabled, it will disable all Virtual
Server entries.
Because our routers use NAT (Network Address Translation), you can only open a
specific port to one computer at a time. For example: If you have 2 web servers on
your network, you cannot open port 80 to both computers. You will need to configure
1 of the web servers to use port 81. Now you can open port 80 to the first computer
and then open port 81 to the other computer.

Frequently Asked Questions (continued)
What is DMZ?
Demilitarized Zone:
In computer networks, a DMZ (demilitarized zone) is a computer host or small
network inserted as a neutral zone between a company´s private network and the
outside public network. It prevents outside users from getting direct access to a
server that has company data. (The term comes from the geographic buffer zone that
was set up between North Korea and South Korea following the UN police action in
the early 1950s.) A DMZ is an optional and more secure approach to a firewall and
effectively acts as a proxy server as well.
In a typical DMZ configuration for a small company, a separate computer (or host in
network terms) receives requests from users within the private network for access to
Web sites or other companies accessible on the public network. The DMZ host then
initiates sessions for these requests on the public network. However, the DMZ host is
not able to initiate a session back into the private network. It can only forward packets
that have already been requested.
Users of the public network outside the company can access only the DMZ host. The
DMZ may typically also have the company´s Web pages so these could be served to
the outside world. However, the DMZ provides access to no other company data. In
the event that an outside user penetrated the DMZ hosts security, the Web pages
might be corrupted but no other company information would be exposed. D-Link, a
leading maker of routers, is one company that sells products designed for setting up
a DMZ
How do I configure the DMZ Host?
The DMZ feature allows you to forward all incoming ports to one computer on the local
network. The DMZ, or Demilitarized Zone, will allow the specified computer to be
exposed to the Internet. DMZ is useful when a certain application or game does not
work through the firewall. The computer that is configured for DMZ will be completely
vulnerable on the Internet, so it is suggested that you try opening ports from the
Virtual Server or Firewall settings before using DMZ.
Step 1
Find the IP address of the computer you want to use as the DMZ host.
To find out how to locate the IP Address of the computer in Windows XP/2000/ME/9x
or Macintosh operating systems please refer to Step 4 of the first question in this
section (Frequently Asked Questions).
