•10/100Base-T Ethernet router to provide Internet connectivity
to all computers on your LAN.
•Network address translation (NAT), Firewall, and IP filtering
functions to provide security for your LAN.
•
Network configuration through DHCP Server and DHCP Relay.

Proceed to Step "Configuring Your Computers".
Configuring Your Computers
This section provides instructions for configuring the Internet
settings on your computers to work with the ADSL Barricade
.
Before you begin
By default, the ADSL Barricade automatically assigns all required
Internet settings to your PCs. You need only to configure the PCs
to accept the information when it is assigned.
Note:
In some cases, you may want to assign Internet
information manually to some or all of your computers
rather than allow the ADSL Barricade to do so. See
Assigning static Internet Information to your PCs for
instructions.
If you have connected your PC via Ethernet to the ADSL
Barricade
, follow the instructions that correspond to the operating
system installed on your PC.

Assigning static Internet Information to your PCs
In some cases, you may want to assign Internet information to
some or all of your PCs directly (often called statically), rather
than allowing the ADSL Barricade to assign it. This option may
be desirable (but not required) if:
•You have obtained one or more public IP addresses that
you want to associate with specific computers (for example, if
you are using a computer as a public web server).
•You maintain different subnets on your LAN (subnets are
described in IP Addresses, Network Masks, and Subnets).
Before you begin, be sure to have the following information on
hand (or contact your ISP if you do not know it):
•The IP address and subnet mask you will assign to each PC
which will be assigned static IP information.
•The IP address of the default gateway for your LAN. In most
cases,thisistheaddressassignedtotheLAN port on theADSL
Barricade
. By default, the LAN port is assigned this IP
address: [
192.168.1.1.] (You can change this number, or
another number
can be assigned by your ISP.) See
Configuring the LAN Ports for more information.
•The IP address of your ISP's Domain Name System (DNS)
server.
On each PC you will assign static information, follow the
instructions on pages 8 through 15 specific to the IP protocol.
Once it is installed, continue
to follow the instructions for
displaying each of the Internet Protocol
(TCP/IP) properties.
Instead of enabling dynamic assignment of the IP addresses for
the computer, the DNS server, and the default gateway, click the
radio buttons that enable you to enter the information manually.
