Configuring Automatic Configuration (DHCP)

If your Internet Service Provider (ISP) uses the Dynamic Host Control Protocol

(DHCP) to assign you an IP address, you will receive a dynamic IP address that is

newly generated each time you log in.

To configure the DHCP settings:

STEP 1

Choose

Networking

>

WAN

>

Internet Setup

.

STEP

2

From the

Internet Connection Type

drop-down menu, choose

Automatic

Configuration - DHCP

.

Configuring PPPoE

To configure the PPPoE settings:

STEP 1

Choose

Networking

>

WAN

>

Internet Setup

.

STEP

2

From the

Internet Connection Type

drop-down menu, choose

PPPoE

.

STEP

In the

PPPoE Settings

area, enter the following information (you may need to

contact your ISP to obtain your PPPoE login information):

Username

Enter your username assigned to you by the ISP.

Password

Enter your password assigned to you by the ISP.

Connect on Demand

Select this option if your ISP charges based on the

amount of time that you are connected. When you

select this option, the Internet connection is on only

when traffic is present. If the connection is idle—that

is, no traffic is flowing—the connection is closed. If you

click

Connect on Demand

, enter the number of

minutes after which the connection shuts off in the

Max

Idle Time

field.

Configuring Static IP

If your ISP assigned you a permanent IP address, perform the following steps to

configure your WAN settings:

STEP 1

Choose

Networking

>

WAN

>

Internet Setup

.

STEP

2

From the

Internet Connection Type

drop-down menu, choose

Static IP

.

STEP

area, enter the following information:

Keep Alive

When you select this option, the Internet connection is

always on.

If you click

Keep Alive

, enter the number of seconds

that the CVR100W attempts to reconnect after it is

disconnected in the

Redial period

field.

Authentication Type

Choose the authentication type:

•

Auto Negotiation:

The server sends a

configuration request specifying the security

algorithm set on it. Then, the CVR100W sends

back authentication credentials with the

security type sent earlier by the server.

•

PAP:

The CVR100W uses the Password

Authentication Protocol (PAP) to connect to the

ISP.

•

CHAP:

The CVR100W uses the Challenge

Handshake Authentication Protocol (CHAP)

when connecting with the ISP.

•

MS-CHAP or MS-CHAPv2:

The CVR100W

uses Microsoft Challenge Handshake

Authentication Protocol when connecting with

the ISP.

Enter subnet mask of the WAN port.

Default Gateway

Enter the IP address of the default gateway.

Static DNS 1

Enter the IP address of the primary DNS server.

Static DNS 2

Enter the IP address of the secondary DNS server.

Host Name

Enter the host name of the CVR100W.

Domain Name

Enter the domain name for your network.

MTU

The Maximum Transmit Unit (MTU) is the size of the

largest packet that can be sent over the network.

The standard MTU value for Ethernet networks is

usually 1500 bytes. For PPPoE connections, the value

is 1492 bytes.

Unless a change is required by your ISP, Cisco

recommends that you choose

Auto

. The default MTU

size is 1500 bytes.

If your ISP requires a custom MTU setting, choose

Manual

and enter the MTU size.

Size

Enter the MTU size.

Cloning the MAC Address

Sometimes, you may need to set the MAC address of the CVR100W’s WAN port to

be the same MAC address as your PC’s or some other MAC address. This is called

MAC address cloning.

For example, some ISP registers your computer’s NIC card MAC address when

the service is first installed. When you place a router behind the cable modem or

DSL modem, the MAC address from the CVR100W’s WAN port is not recognized

by the ISP.

In this case, to configure your CVR100W to be recognized by the ISP, clone the

MAC address of the WAN port to be the same as your computer’s MAC address.

To configure a MAC address clone:

STEP 1

Choose

Networking

>

WAN

>

MAC Address Clone

.

STEP

2

In the

MAC Address Clone

field, check

Enable

to enable MAC address cloning.

STEP

3

Set the MAC address of the CVR100W’s WAN port, do one of the following:

•

To set the MAC address of the WAN port to your PC’s MAC address,

click

Clone My PC’s MAC

.

•

To specify a different MAC address, enter it in the

MAC Address

field.

Configuring LAN Settings

The default DHCP and TCP/IP settings work for most applications. You can assign

an IP address to each additional logical subnet on the CVR100W.

Configuring Basic LAN Settings

You can configure the CVR100W’s IP address and DHCP settings.

IPv4

To configure the default LAN IP address of the CVR100W:

STEP 1

Choose

Networking

>

LAN

>

LAN Configuration

.

STEP

2

In the

IPv4

area, enter the following information:

STEP

3

Click

Save

.

After the CVR100W’s LAN IP address is changed, your PC is no longer connected

to the CVR100W.

STEP

4

To reconnect your PC to the CVR100W, do one of the following:

•

If DHCP is configured on the CVR100W, release and renew your PC’s IP

address.

•

Manually assign an IP address to your PC. The address must be on the same

subnet as the CVR100W. For example, if you change the CVR100W’s IP

address to 10.0.0.1, assign your PC an IP address in the range of 10.0.0.2 to

10.0.0.255.

VLAN

Choose the VLAN number from the drop-down menu.

Local IP Address

Enter the LAN IP address of the CVR100W.

Make sure the address is not in use by another device.

Subnet mask

Choose the subnet mask for the new IP address from

the drop-down menu. The default subnet is

255.255.255.0.
