The Setup Tab - Basic Setup

Static IP

If you are required to use a permanent IP address, then select

Static IP

.

IP Address

. This is the IP address that the Router has, when seen from the Internet. Your ISP will provide

you with the IP Address you need to specify here.

Subnet Mask

. This is the Router’s Subnet Mask, as seen by external users on the Internet (including your

ISP). Your ISP will provide you with the Subnet Mask.

Gateway

. Your ISP will provide you with the Default Gateway Address.

DNS 1-3

. Your ISP will provide you with at least one DNS (Domain Name System) Server IP Address.

WINS

. The Windows Internet Naming Service (WINS) converts NetBIOS names to IP addresses. If you use a

WINS server, enter that server’s IP address here. Otherwise, leave this field blank.

PPPoE

Some DSL-based ISPs use PPPoE (Point-to-Point Protocol over Ethernet) to establish Internet connections for

end-users. If you use a DSL line, check with your ISP to see if they use PPPoE. If they do, you will have to

enable it.

User Name and Password

. Enter the User Name and Password provided by your ISP.

Chapter 5: Configuring the Router

The Setup Tab - Basic Setup

Keep Alive and Redial Period

. This option keeps your Internet access connected indefinitely, even when it

sits idle. If you select this option, the Router will periodically check your Internet connection. If the

connection is down, then the Router will automatically re-establish the connection. To use this option, click

the radio button next to

Keep Alive

. The default Redial Period is

45

seconds.

When you are finished, click the

Save Settings

button. Then click the

Status

tab, and click the

Connect

button to start the connection.

Optional Settings

Some of these settings may be required by your ISP. Verify with your ISP before making any changes.

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 identification. 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.

MTU

. The MTU (Maximum Transmission Unit) setting specifies the largest packet size permitted for network

transmission. Select

Auto

to have the Router automatically select the MTU value, or select

Manual

and enter the

value desired. It is recommended that you leave this value in the 1200 to 1500 range. For two Internet connection

types, Obtain an IP automatically and Static IP, the MTU’s default value is

1500

. For PPPoE, the MTU’s default

value is

1492

.

Network Setup

The Network Setup section allows you to change the Router’s local network settings.

NOTE:

For DSL users, if you

need to enable PPPoE support,

remember to remove any PPPoE

applications that are installed

on your PCs.

The Setup Tab - Basic Setup

Router IP

The values for the Router’s Local IP Address and Subnet Mask are shown here. In most cases, keeping the

default values will work.

Local IP Address

. The default value is

192.168.15.1

.

Subnet Mask

. The default value is

255.255.255.0

.

Network Address Server Settings (DHCP)

These settings allow you to configure the Router’s Dynamic Host Configuration Protocol (DHCP) server function.

The Router can be used as a DHCP server for your network. A DHCP server automatically assigns an IP address

to each computer on your network. Unless you already have one, it is highly recommended that you leave the

Router enabled as a DHCP server.

Local DHCP Server

. DHCP is enabled by factory default. If you already have a DHCP server on your network, set

the Router’s DHCP option to

Disable

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

DNS Proxy

. DNS Proxy is enabled by factory default.

Start IP Address

. Enter a value for the DHCP server to start with when issuing IP addresses. Because the

default IP address for the Router is 192.168.15.1, the Start IP Address must be 192.168.15. 101 or greater, but

smaller than 192.168.15.254. The default Start IP Address is

192.168.15.100

.

Number of Address

(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. The default is

50

.

DHCP Address Range

. The range of DHCP addresses is displayed here.

The Setup Tab - DDNS

Client Lease Time

. The Client Lease Time is the amount of time a network user will be allowed connection to the

Router with their current dynamic IP address. Enter the amount of time, in minutes, that the user will be “leased”

this dynamic IP address. After the dynamic IP address has expired, the user will be automatically assigned a new

dynamic IP address. The default is

0

minutes, which means one day.

WINS

. The Windows Internet Naming Service (WINS) converts NetBIOS names to IP addresses. If you use a WINS

server, enter that server’s IP address here. Otherwise, leave this field blank.

The Setup Tab - DDNS

The Router offers a Dynamic Domain Name System (DDNS) feature. DDNS lets you assign a fixed host and

domain name to a dynamic Internet IP address. It is useful when you are hosting your own website, FTP server,

or other server behind the Router.

Before you can use this feature, you need to sign up for DDNS service at one of two DDNS service providers,

DynDNS.org or TZO.com. If you do not want to use this feature, keep the default setting,

Disable

.

dynamic ip address

: a temporary IP

address assigned by a DHCP server.

ddns

: allows the hosting of a website, FTP

server, or e-mail server with a fixed

domain name (e.g., www.xyz.com) and a

dynamic IP address.
