seen this screen and properly configured all of the screen’s values.

• Host Name

and

Domain Name

These fields allow you to supply a host and

domain name for the Router. Some ISPs require these names as identifica-

tion. You may have to check with your ISP to see if your broadband Internet

service has been configured with a host and domain name. In most cases,

leaving these fields blank will work.

• Firmware Version

This entry shows the version and date of the firmware

you are using. Future versions of the Router’s firmware will be posted and

available for download on the Network Everywhere website at

Chapter 6: The Router’s

Web-based Utility

Use the Router’s web-based utility to administer it. This chapter will describe

each web page in the Utility and each page’s key functions. The utility can be

accessed via your web browser through use of a computer connected to the

Router.

For a basic network setup, most users only have to use the following screens of

the utility:

• Setup

Enter the settings provided by your ISP.

• Password

The Router’s default password is

admin

. To secure the Router,

change the Password from its default.

The Status, DHCP, Log, and Help tabs are also available for basic setup. For

advanced setup, click the Advanced tab to access these screens: IP Filtering,

Port Range Forwarding, Dynamic Routing, Static Routing, DMZ Host, and

MAC Address Clone.

To access the web-based utility of the Router, launch Internet Explorer or

Netscape Navigator, and enter the Router’s default IP address,

192.168.1.1

, in

the Address field. Then press

Enter

PPPoE

Some DSL-based

ISPs use PPPoE

(Point-to-Point

Protocol

over

Ethernet) to estab-

lish Internet con-

nections. If you are

connected to the

Internet through a

DSL line, check

with your ISP to

see if they use

PPPoE. If they do,

you will have to

enable PPPoE.

User Name and Password

Enter the

User Name

and

Password

provided

by your ISP.

Connect on Demand: Max Idle Time

You can configure the Router to cut

the connection with your ISP after a specified period of time (Max Idle

Time). If you have been disconnected due to inactivity, Connect on Demand

enables the Router to automatically re-establish your connection as soon as

you attempt to access the Internet again. If you wish to activate Connect on

Demand, click the radio button. In the Max Idle Time field, enter the num-

ber of minutes you want to have elapsed before your Internet access dis-

connects.

Keep Alive Option: Redial Period

If you select this option, the Router will

periodically check your Internet connection. If you are disconnected, then

the Router will automatically re-establish your connection.

To use this

option, click the radio button next to

Keep Alive

. In the Redial Period field,

enter the number of seconds you want the Redial Period to last. The default

Redial Period is 30 seconds.

LAN

These fields display the Router’s current MAC Address, IP Address, and

Subnet Mask, as seen by users on your local area network. The DHCP Server

field shows the status of the Router’s DHCP server function, which is either

enabled or disabled.

WAN

These fields display the Router’s current MAC Address, IP Address,

Subnet Mask, and Default Gateway IP Address, as seen by external users on the

Internet. The DNS (Domain Name System) IP Address fields show the IP

address(es) of the DNS server(s) currently used by the Router. Multiple DNS

IP settings are common. In most cases, the first available DNS entry is used.

DHCP Release

Click the

DHCP Release

button to release the current IP

address of the device connected to the Router’s Internet (or WAN) port.

DHCP Renew

Click the

DHCP Renew

button to replace the Router’s current

WAN IP address with a new IP address.

DHCP Clients Table

Click the

DHCP Clients Table

button to view the list of

PCs that were given IP addresses by the Router.

This screen displays the Router’s current status; it reflects the data and selec-

tions you’ve entered using the Setup screen.

All of the information provided on this screen is read-only.

To make changes,

select the Setup tab.

Host Name

This field shows the Router’s name.

Firmware Version

This field shows the installed version and date of the

For PPPoE only, there is a

Connect

button to click if you are disconnected and

want to re-establish a connection.

DNS

The Domain Name System (DNS) is how the Internet translates domain

or website names into Internet addresses or URLs. Your ISP will provide you

with at least one DNS Server IP Address. If you wish to use another, type that

IP Address in one of these fields. You can type up to three DNS Server IP

Addresses here. The Router will use these for quicker access to functioning

DNS servers.

DHCP Clients Table

Click the

DHCP Clients Table

button to show the cur-

rent DHCP Client data. (This data is stored in temporary memory and changes

periodically.)

A Dynamic Host Configuration Protocol (DHCP) server automatically assigns

an IP address to each PC on your network for you. Unless you already have one,

it is highly recommended that you leave the Router enabled as a DHCP server.

DHCP Server

DHCP is already enabled by factory default.

If you already

have a DHCP server on your network, set the Router’s DHCP option to

Disable

. Click the

Apply

button and then the

Continue

button.

If you disable

DHCP, remember to assign a static IP address to the Router.

Starting IP Address

Enter a value for the DHCP server to start with when

issuing IP addresses.

This value must be 192.168.1.2 or greater, because the

Router’s default IP address is

192.168.1.1

Number of DHCP Users

(Optional) Enter the maximum number of PCs that

you want the DHCP server to assign IP addresses to. This number cannot be

greater than 253.

In order to determine the DHCP IP Address range, add the

last three digits of the starting IP address (e.g., 100) to the number of DHCP

users.

By default, as shown in Figure 6-8, add 100 to 50 (number of DHCP

users), and the range is 192.168.1.100 to 192.168.1.149.
