Setup Basic Settings – Network Configuration Page Description

The following table provides a description of the fields within the Setup Basic

Settings – Network Configuration page.

Field Name

Description

LAN IP

The base IP address of the private home LAN and the

Address

WebWizard IP address. Your gateway cable modem assigns

 

private IP addresses to your attached computers by its internal

 

dynamic host configuration protocol (DHCP) server

MAC

The MAC address for the WAN. The factory assigned MAC

Address

address for the WAN is also referred to as the WLAN Data

 

MAC address unless a spoofed MAC address is used. (See

 

Spoofed MAC Address later in this table)

WAN IP

The public IP address assigned to your cable modem by your

Address

ISP. The WAN will be assigned a public IP address by your

 

cable service provider. The WAN IP address will be shared by

 

all the PCs in your private local area network to access the

 

Internet

Duration

The length of time your WAN IP address is valid. This length

 

of time renews when this duration expires

Expires

The date and time your WAN IP address expires

Host Name

Some ISPs require this information for authentication and will

 

supply it to you

Domain

Some ISPs require this information for authentication and will

Name

supply it to you

Static IP

Some ISPs require this information for authentication and will

Address

supply it to you

 

When setting a static IP address, you must enter the IP

 

address, subnet mask, and default gateway before the static

 

IP address will become operational

Static IP

Some ISPs require this information for authentication and will

Mask

supply it to you

Default

Some ISPs require this information for authentication and will

Gateway

supply it to you

Primary DNS

Some ISPs require this information for authentication and will

 

supply it to you

Secondary

Some ISPs require this information for authentication and will

DNS

supply it to you

Spoofed

Some ISPs require the MAC address of the network interface

MAC

card (NIC) in your computer for authentication. When installing

Address

the gateway cable modem, you can enter your computer MAC

 

address here to allow you to connect to your ISP. If a Spoofed

 

MAC address is used, the gateway will use the Spoofed MAC

 

address to obtain the public WAN IP address in place of using

 

the WLAN Data MAC address assigned at the factory

Setup Basic Settings – IP Management Page Description

The following tables provide a description of the fields within the Setup Basic

Settings – IP Management page.

Field Name

DHCP Server

Starting Local Address

Number of CPEs

DHCP Client Lease Info

Function Keys

Description

Allows you to enable or disable the DHCP server

The starting address used by the built-inDHCP server to distribute Private LAN IP addresses. In the example shown, addresses between 2 and 9 can be used for devices on your Private LAN that require fixed IP addresses such as printers or a device assigned as a DMZ host

The LAN IP address ending in 1 is reserved for the internal gateway server. The LAN IP address ending in 255 is also reserved and should not be used for CPE devices

Enter the maximum number of devices allowed to connect to the Private LAN.

The maximum number of devices is 255. This is the combined total of addresses reserved for static IP addresses, for example, the sum of the IP addresses between 1 and the value entered in the Starting Local Address field and the value entered in the Number of CPEs field.

Note: The sum of the value entered in the Starting Local Address field and the value entered in the Number of CPEs field mustalways be 255 or less.

Displays the MAC address, IP Address, Subnet Mask, Duration and Expiration date of all devices issued an IP address by the built-inDHCP server. This field also displays the current system time and date

Reserving IP Addresses

Use the Setup Basic Settings – Fixed CPE IP Assignment page to reserve IP addresses to be issued by the DHCP server in the gateway to specific devices on the LAN. This feature allows you to assign a fixed IP address to any device in your network and eliminates the need to set static IP addresses in your PC or other network device.

Reserving IP addresses is useful in making sure that a particular PC or other network device (for example, a printer) is always issued the same IP address. Another example: when using DMZ Host, the IP address for the DMZ Host will always be issued to the same PC or device.

If you are not familiar with the Fixed CPE IP Assignment procedures detailed in this section, contact your cable service provider before you attempt to change any of the gateway cable modem default Fixed CPE IP Assignment settings.

Click Fixed CPE IP Assignment in the Basic Settings section of the Setup page to access the Setup Basic Settings – Fixed CPE IP Assignment page.

Assign to IP

The IP address you assign to the PC or device for which

 

you want to reserve a specific IP address on the

 

network (for example, 192.168.0.7). The factory

the gateway. Access to the set-upparameters is

 

obtained by using the password to access the

 

WebWizard.

 

Enable this feature by checking the Remote Config

 

Management box on the Setup Advanced Settings –

 

Options page. To access your gateway from a remote

 

location, you must also know the WAN IP address of the

 

gateway. To find the WAN IP address, go to the

 

Network Configuration page under Basic Settings. You

 

will find the gateway’s WAN IP address list on this page.

 

Enter the WAN IP address of your gateway into the

 

address field of any Web browser using the following

 

format: http://xxx.xxx.xxx.xxx:8080 where

 

xxx.xxx.xxx.xxx represents the WAN IP address of your

 

gateway.

 

Be sure to follow the syntax exactly, and then click Go

 

or press Enter. Your gateway Web pages will appear on

 

the remote computer. You will still need to enter your

 

password to access the Setup pages of your gateway
