■
Primary DNS Address
— The address of your ISP’s Domain
Name Service server is automatically configured but may be
edited.
■
Secondary DNS Address
— The address of your ISP’s
secondary Domain Name Service server. The second server is
optionally provided by an ISP in case of failure of the primary
server.
■
Host Name
— The Host Name of your computer may be
required by your ISP.
■
PPPoE User Name
— The user name you use to access your
ISP.
■
PPPoE Password
— The password you use to access your ISP.
■
PPPoE Service Name
— Your ISP may require you to specify a
service name for your connection.
■
Maximum Idle Time
— The amount of time without activity
before the Gateway terminates the Internet connection.
Since the Gateway firmware contains its own PPPoE client, you
no longer need to run PPPoE client software on your computer
to access the Internet. You can simply start your browser and
connect to the Internet immediately after setting up your cable
or DSL modem.
Setting up NAT
The Gateway is able to perform Network Address Translation
(NAT) in one of two modes as shown in
Figure 34
:
■
One-to-many NAT
— The Gateway shows only one address to
the Internet.
■
One-to-one NAT
— Every address on the Internet pool is
linked to an address in the LAN pool. The Gateway will
respond to all the addresses in the Internet pool.
