Frequently Asked Questions (continued)

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:

http://support.dlink.com

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

Step 2

.

Note:

Do not run Wizard.

Step 4

Click on the

WAN

tab on left-hand side of the screen. Select

PPPoE

.

Step 5

Select

Dynamic PPPoE

(unless your ISP supplied you with a static IP

Address).

Step 6

In the username field enter

ELN/[email protected]

and your

password, where username is your own username.

For SBC Global users, enter

.

For Ameritech users, enter

.

For BellSouth users, enter

.

For Mindspring users, enter

[email protected].

For most other ISPs, enter

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.

78

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

. Click

Continue

when prompted. You should

now see that the device info will show an IP Address, verifying that the device has

connected to a server and has been assigned an IP Address.

connection? (continued)

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

http://www.aol.com

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).
