DIR-100 Ethernet Broadband Router

Dynamic IP Address

A Dynamic IP Address connection configures the Router to automatically obtain its global IP address from a

DHCP server on the ISP’s network.

To configure a Dynamic IP Address connection, perform the steps listed below.

Dynamic IP Address connection setup menu

To configure a Dynamic IP Address Internet connection, follow these steps:

1. Select the

Dynamic IP (DHCP)

option from the

My Internet Connection is:

pull-down menu.

2. Under the

Dynamic IP

heading, type a Host Name if needed, and DNS IP address information. The

Primary DNS Address

will be normally be required, the

Secondary DNS Address

is used for a

back up DNS server.

3.

Some ISPs record the unique MAC address of your computer’s Ethernet adapter when you first

access their network. This can prevent the Router (which has a different MAC address) from being

allowed access to the ISPs network (and the Internet). To clone the MAC address of your computer’s

Ethernet adapter, type in the MAC address in the

MAC Address

field and click the

Clone MAC

Address

button.

4. Leave the

MTU

value at the default setting (default =

1500

) unless you have specific reasons to

change this (see table below for more information).

5.

Click on the Save Settings button to save and apply the new Internet connection settings.

Settings for Dynamic IP Address connections:

IP Address

Enter the IP address based on the information provided to you by your

ISP.

Subnet Mask

Enter the Subnet Mask based on the information provided to you by

your ISP.

ISP Gateway

Address

Enter the Default Gateway based on the information provided to you

by your ISP.

MAC Address

This field will instruct the user to enter the Media Access Control

(MAC) address of the Ethernet Card of your computer, if instructed to

do so by your ISP. To quickly accomplish this, click the

Duplicate

MAC address from the customer end

button, which will

automatically copy the MAC address of your Ethernet card and enter it

into the space provided, which will replace the MAC address of the

router.

Primary DNS

Address

This entry is for the IP address of your primary domain name server,

which should also be provided to you by your ISP. The router will first

try the

Primary DNS Address

to resolve a website’s URL IP address.

If this IP address fails, the router will then try the

Secondary DNS

Address

.

Secondary DNS

Address

The IP address of the secondary domain name server will be used to

resolve a website’s URL IP address if the

Primary DNS Address

fails.

The information in this field should also be provided by your ISP.

MTU

This field refers to the Maximum Transfer Unit, which is the maximum

size of a packet, in bytes, that will be accepted by the router. The

default setting is 1500 bytes. This field should not be altered unless

instructed by your ISP.

21

Static IP Address

When the Router is configured to use Static IP Address assignment for the Internet connection, you must

manually assign a global IP Address, Subnet Mask, and ISP Default Gateway IP address. Most users will

also need to configure DNS server IP settings. Follow the instruction below to configure the Router to use

Static IP Address assignment for the Internet connection.

Static IP Address connection setup menu

To configure a Static IP type Internet connection, follow these steps:

1. Select the

Static IP

option from the

My Internet Connection is:

pull-down menu.

2. Under the

Static IP

heading, type IP address information provided by your ISP, type an

IP Address

,

Subnet Mask

and

ISP Gateway Address

. The

Primary DNS Address

will be normally be

required, the

Secondary DNS Address

is used for a back up DNS server.

3.

Some ISPs record the unique MAC address of your computer’s Ethernet adapter when you first

access their network. This can prevent the Router (which has a different MAC address) from being

Ethernet adapter, type in the MAC address in the

MAC Address

field and click the

button.

4. Leave the

) unless you have specific reasons to

change this (see table below for more information).

Settings for Static IP Address connections:

Host Name

This field will require the user to enter the host name of the

connection, if instructed by your ISP. If not instructed, the user may

leave this field blank or leave the default name of

DIR-100

as the host

name.

MAC Address

This field will instruct the user to enter the Media Access Control (MAC)

address of the Ethernet Card of your computer, if instructed to do so by

your ISP. To quickly accomplish this, click the

Duplicate MAC address

from the customer end

button, which will automatically copy the

MAC address of your Ethernet card and enter it into the space

provided, which will replace the MAC address of the router.

Primary DNS

Address

This entry is for the IP address of your primary domain name server,

which should also be provided to you by your ISP. The router will first

try the Primary DNS Address to resolve a website’s URL IP address. If

this IP address fails, the router will then try the Secondary DNS

Address.

Secondary DNS

Address

The IP address of the secondary domain name server will be used to

resolve a website’s URL IP address if the

Primary DNS Address

fails.

The information in this field should also be provided by your ISP.

This field refers to the Maximum Transfer Unit, which is the maximum

size of a packet, in bytes, that will be accepted by the router. The

default setting is 1500 bytes. This field should not be altered unless

instructed by your ISP.

PPPoE

PPP or Point-to-Point protocol is a standard method of establishing a network connection/session between

networked devices. Different forms of PPP include PPPoA and PPPoE (discussed below) involve an

authentication process that requires a username and password to gain access to the network. PPPoE (PPP

over Ethernet), as described in RFC 2516, is a method of using PPP through the Ethernet network.

To configure the connection for PPPoE, perform the steps listed below. Some of the settings do not need to

be changed the first time the device is set up, but can be changed later if you choose. The information that is

to be provided in this window must be given to you by your ISP and must be carefully configured. Any small

discrepancy will send the wrong message to your ISP’s server and inhibit your connection.

There are two ways to configure the PPoE connection on the router, one is for a

Dynamic PPPoE

configuration, which means the router will implement some settings automatically through DHCP, such as

the router’s IP address and the default gateway. The other is through a

Static PPPoE

connection, in which

the user must configure the IP address and the DNS addresses automatically.

Follow the instructions below to configure the Router to use a PPPoE Internet connection.

PPPoE connection setup menu

To configure a PPPoE Internet connection, follow these steps:

1. Select the

PPPoE (Username / Password)

option from the

My Internet Connection is:

pull-down

menu.

2.

Choose the IP address assignment option (Dynamic PpoE or Static PPPoE). Static IP address

assignement requires manual entry of IP settings information.

3. Under the

PPPoE

heading, type the

User Name

and

Password

used for your account. A typical

User Name will be in the form

. 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.

Type the password

again in

Confirm Password

.

4.

For Static PPPoE connections, enter IP settings provided by the ISP and, if necessary enter MAC

address (see table below)

5. Leave the

MTU

value at the default setting (default =

1492

) unless you have specific reasons to

change this (see table below for more information).

6. Choose the desired

Connection Setting

. Select from: Always ON, Connection On Demand, or

Manual. Most users will want to choose the default connection setting, Always ON.
