DHCP Server
Correctly configuring all the TCP/IP settings of the computers in your home
network is a complicated and time-consuming task. Fortunately, the setup
program provides a simple approach to handle all these settings. Instead of setting
up each computer separately, the gateway can act as a DHCP server, alloting each
computer on your home network an IP address.
To activate the DHCP Server option, click the Enable check box that corresponds to
DHCP Server.
DMZ Host
A DMZ (De-Militarized Zone) Host is a computer without the protection of firewall.
This state allows the computer to be exposed to unrestricted 2-way communication
from outside of your home network. This feature should be used only if the Virtual
Server or Special Applications options do not provided the level of access needed for
certain applications.
To configure one of your computers as a DMZ host, enter the last digit(s) of the IP
address of the computer in the IP Address of DMZ Host text box, and then click
the Enable check box.
Setup Program

Remote Administrator Host
In general, only a user on your home network can use the setup program of
the gateway. The remote administrator host feature enables you to perform
administration tasks from a remote host, that is, a computer not a part of your
home network.
To activate the remote administrator host feature, enter the IP address of the
remote host in the Remote Administrator Host text box. If the IP address entered is
0.0.0.0, any host can connect to the gateway to perform administration tasks,
provided the user knows the IP address of the gateway. Then, click the Enable
check box that corresponds to Remote Administrator Host.
When this feature is enabled, the Web port will be shifted to 88.

GLOSSARY
Analog modem
Analog modem uses existing phone lines to send and receive data.
DHCP
Dynamic Host Configuration Protocol. This protocol automatically configures the
TCP/IP settings of every computer on your home network.
DNS Server Address
DNS stands for Domain Name System, which allows Internet host computers to
have a domain name (such as 3com.com) and one or more IP addresses (such
as 192.34.45.8). A DNS server keeps a database of host computers and their
respective domain names and IP addresses, so that when a domain name is
requested (as in typing “3com.com” into your Internet browser), the user is sent
to the proper IP address. The DNS server address used by the computers on your
home network is the location of the DNS server your ISP has assigned.
DSL modem
Ethernet
IP address
ISDN modem
ISP
DSL stands for digital subscriber line. A DSL modem uses your existing phone lines
to send and receive data at high speeds.
A standard for computer networks. Ethernet networks that are connected by
special cables and hubs move data around at up to 100 million bits per second
(Mbps).
IP stands for Internet Protocol. An IP address, which consists of a series of four
numbers separated by periods, identifies a single, unique Internet computer host.
Example: 192.34.45.8.
ISDN stands for Integrated Services Digital Network. An ISDN modem uses your
existing phone lines to send and receive data at higher speeds than analog modems.
Internet service provider. An ISP is a business that provides connectivity to the
Internet for individuals, businesses, and organizations.
LAN
Local area network. A LAN is a group of computers and devices connected
together in a relatively small area (such as a house or office). Your home network
is considered a LAN.
MAC address
MAC stands for media access control. A MAC address is the hardware address of a
device connected to a network.
NAT
Network address translation. This process allows all of the computers on your
home network to use one IP address. Using the NAT capability of the Home
Ethernet Gateway, you can access the Internet from any computer on your home
network without having to purchase more IP addresses from your ISP.
Print server
A device that enables a printer to be shared across a network. The Home Ethernet
Gateway can be used as a print server for your home network.

GLOSSARY
PPPoE
Point-to-Point Protocol over Ethernet. Point-to-Point Protocol is a method of
secure data transmission originally created for dial-up connections; PPPoE is for
Ethernet connections.
subnet mask
A subnet mask, which may be a part of the TCP/IP information provided by your
ISP, is a set of four numbers configured like an IP address. It is used to create IP
address numbers used only within a particular network (as opposed to valid IP
address numbers recognized by the Internet, which must assigned by InterNIC).
TCP/IP
Transmission Control Protocol/Internet Protocol. This is the standard protocol for
data transmission over the Internet.
WAN
Wide area network. A network that connects computers located in geographically
separate areas, (i.e., different buildings, cities, countries). The Internet is an
example of a wide area network.
