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.
•

•
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.
•

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

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.
