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
.
STEP

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

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.

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.
