RFC 2516 PPPoE

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

•

Service Name. Enter the name of your PPPoE service in the field.

•

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

•

Connect on Demand: Max Idle Time. You can configure the Gateway to disconnect the Internet

connection after it has been inactive for a specified period of time (Max Idle Time). If your Internet

connection has been terminated due to inactivity, Connect on Demand enables the Gateway 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

number of minutes you want to have elapsed before your Internet connection terminates.

•

Keep Alive: Redial Period. If you select this option, the Gateway will periodically check your Internet

connection. If you are disconnected, then the Gateway will automatically re-establish your connection.

To use this option, click the radio button next to

Keep Alive

. In the Redial Period field, you specify how

often you want the Gateway to check the Internet connection.

The default Redial Period is 30 seconds.

Chapter 5: Configuring the Gateway

The Setup Tab

ADSL2 Gateway with 4-Port Switch

Optional Settings (Required by some ISPs)

•

Host Name and Domain Name. These fields allow you to supply a host and domain name for the Gateway.

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

Manual

and enter the value desired in the

Size

field. It is recommended that you leave

this value in the 1200 to 1500 range. By default, MTU is configured automatically.

Network Setup

•

Router IP. The values for the Gateway’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 192.168.1.1.

•

Subnet Mask. The default value is 255.255.255.0.

•

Network Address Server Settings (DHCP). A Dynamic Host Configuration Protocol (DHCP) server automatically

assigns an IP address to each computer on your network for you. Unless you already have one, it is highly

recommended that you leave the Gateway enabled as a DHCP server.

•

DHCP Relay Server. If you enable the Local DHCP Server or DHCP Relay for the Local DHCP server, enter

the IP address for the DHCP server in the fields.

•

AutoDetect LAN DHCP Server.

•

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 default IP address for the Gateway is 192.168.1.1.

•

Maximum Number of DHCP Users. Enter the maximum number of users/clients that can obtain an IP

address. The number will vary depending on the starting IP address entered.

•

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

to the Gateway with their current dynamic IP address. Enter the amount of time, in minutes, that the user

will be “leased” this dynamic IP address.

•

Static DNS 1-3. 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. You

Figure 5-9: Optional Settings

Chapter 5: Configuring the Gateway

The Setup Tab

ADSL2 Gateway with 4-Port Switch

can enter up to three DNS Server IP Addresses here. The Router will use these for quicker access to

functioning DNS servers.

•

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.

•

Time Setting. This is where you set the time zone for your Gateway. Select your time zone from the drop-

down menu. If desired, check the

Automatically adjust clock for daylight saving changes

.

The DDNS Tab

The Gateway 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 Gateway.

Before you can use this feature, you need to sign up for DDNS service at DynDNS.org.

•

User Name, Password, and Host Name. Enter the User Name, Password, and Host Name of the account you

set up with DynDNS.org.
