CHAPTER 1
1.1About the Gateway
The Gateway provides Internet access to multiple users by
sharing a single-user account. The Gateway's most outstanding features include wireless LAN connectivity, as well as
the dual-port WAN interface which allows you to connect to
an xDSL or Cable modem, ISDN TA or PSTN analog
modem. The Gateway provides extensive firewall protection
and Virtual Private Network (VPN) services. It also provides print services for any client attached to a LAN port.
The Gateway supports dial-on-demand for ISDN/PSTN
service, automatically connecting to the Internet when there
are requests, and terminating the connection if no further
requests occur. This dual-port design also supports fail-over
Internet access through the secondary WAN port (i.e., the
serial port can be used for primary or backup Internet
access).
This new Gateway technology provides many cost-effective
functions and management benefits. It is simple to configure
and can be up and running in minutes.

CHAPTER 1
1.3Applications
Many advanced applications are provided by the
Gateway, such as:
zFlexible LAN Access
The Gateway provides connectivity to 10/100 Mbps wired
devices as well as 11 Mbps wireless mobile users. The
wireless interface makes it easy to create a network in difficult-to-wire environments, or to provide quick access to
databases for mobile workers.
zInternet Access
This device supports Internet access through an xDSL,
Cable, ISDN or PSTN connection. Since many xDSL
providers use PPPoE to establish communications with end
users, the Gateway includes a built-in client for this protocol, eliminating the need to install this service on your
computer.
zShared IP Address
The Gateway provides Internet access for up to 253 users
with a shared IP address. Using only one ISP account, multiple users on your network can browse the Web at the
same time.
zVirtual Server
If you have a fixed IP address, you can set up the Gateway
to act as a virtual host for network address translation.
Remote users access various services at your site using a
constant IP address. Then, depending on the requested
1-5
CHAPTER 1
service (or port number), the Gateway can route the request
to the appropriate server (at another internal IP address).
This secures your network from direct attack by hackers,
and provides more flexible management by allowing you to
change internal IP addresses without affecting outside
access to your network..
zUser-Definable Application Sensing Tunnel
You can define special applications that require multiple
connections such as videoconferencing, Internet gaming,
and Internet telephony. The Gateway can then sense the
application type and open a multi-port tunnel for it.
zDMZ Host Support
Allows a networked computer to be fully exposed to the
Internet. This function is used when the special application
sensing tunnel feature is insufficient to allow an application
to function correctly.
zSecurity
The Gateway supports security features that can deny
Internet access to specified users, or filter all requests for
specific services the administrator does not want to serve.
The Gateway's firewall can also block common hacker
attacks, including IP Spoofing, Land Attack, Ping of Death,
IP with zero length, Smurf Attack, UDP port loopback,
Snork Attack, TCP null scan, and TCP SYN flooding.
zVirtual Private Network
The Gateway supports three of the most commonly used
1-6
CHAPTER 1
VPN protocols - PPTP, L2TP and IPSec. These protocols
allow remote users to establish a secure connection to their
corporate network. If your service provider supports VPNs,
then any of these protocols can be used to create an
authenticated and encrypted tunnel for passing secure data
over the Internet (i.e., a traditionally shared data network).
The VPN protocols supported by the Gateway are briefly
described below:
*Point-to-Point Tunneling Protocol: Provides a secure
tunnel for remote client access to a PPTP security gateway. PPTP includes provisions for call origination and
flow control required by ISPs.
*Layer Two Tunneling Protocol - Includes most of the
features provided by PPTP, but has fewer overheads and
is more suited for managed networks.
*IP Security - Provides IP network-layer encryption.
IPSec can support large encryption networks (such as
the Internet) by using digital certificates for device
authentication

CHAPTER 2
2.2 Description of Hardware
The main functions of the Gateway can be divided into
three categories:
1.Connects to the Internet or to a remote site by using its
RJ-45 WAN port or RS232 serial port.
2.Directly connects to your PC or to a local area network
by using any of the three Fast Ethernet LAN ports or
through the IEEE802.11b wireless interface.
3.Functions as a print server as well.
Access speed to the Internet depends on your service type.
Full-rate ADSL can provide up to 8 Mbps downstream and
640 Kbps upstream. G.lite (or splitterless) ADSL provides
up to 1.5 Mbps downstream and 512 Kbps upstream. Cable
modems can provide up to 36 Mbps downstream and 2
Mbps upstream. ISDN can provide up to 128 Kbps when
using two bearer channels. And PSTN analog connections
can now run up to 56 Kbps. However, you should note that
the actual rate provided by specific service providers may
vary dramatically from those above-mentioned limits.
Although access speed to the Internet is determined by the
modem type connected to your Gateway, data passing
between devices connected to your local area network can
run up to 100 Mbps over the Fast Ethernet ports.
The Gateway includes an LED display on the front panel
for system power and port indications that simplifies installation and network troubleshooting. It also provides three
RJ-45 LAN ports, one RJ-45 WAN port, one RS232 serial
2-4
CHAPTER 2
port, one parallel printer port, as well as two antennas on
the rear panel.
zThree RJ-45 ports for connection to a 10BASE-
T/100BASE-TX Ethernet Local Area Network (LAN).
These ports can auto-negotiate the operating speed to
10/100 Mbps, the mode to half/full duplex, and the pin
signals to MDI/MDI-X (i.e., allowing these ports to be
connected to any network device with straight-through
cable). These ports can be connected directly to a PC or to
a server equipped with an Ethernet network interface card,
or to a networking device such as an Ethernet hub or
switch.
zOne RJ-45 port for connection to an xDSL or Cable
modem. This port is fixed at 10 Mbps, full duplex.
zOne RS232 serial port to connect to an ISDN Terminal
Adapter (TA) or to a PSTN analog modem.
zOne parallel printer port that can be connected to a printer,
which can be shared by any LAN/WLAN users.
zTwo antennas.

CHAPTER 2
2.4.2 Attach to Your Network Using Ethernet
Cabling
The three LAN ports on the Gateway can auto-negotiate the
connection speed to 10 Mbps Ethernet or 100 Mbps Fast
Ethernet, as well as the transmission mode to half duplex or
full duplex. These LAN ports also support auto-configuration for pin signals (auto-MDI/MDI-X) that allows you to
use straight-through cable for connecting the Gateway to
any network device. (See Appendices "B. Cables" for
details on wiring.)
Use twisted-pair cable to connect any of the three LAN
ports on the Gateway to an Ethernet adapter on your PC.
Otherwise, you can cascade any of LAN ports on the
Gateway to an Ethernet hub or switch, and then connect
your PC or other network equipment to the hub or switch.
When inserting an RJ-45 plug, be sure the tab on the plug
clicks into position to ensure that it is properly seated.
Warning:
Do not plug a phone jack connector into any RJ-45 port.
This may damage the Gateway. Instead, use only twistedpair cables with RJ-45 connectors that conform to FCC
standards.
2-10
CHAPTER 2
Notes:
1.Use 100-ohm shielded or unshielded twisted-pair cable
with RJ-45 connectors for all connections. Use Category
3, 4 or 5 for connections that operate at 10 Mbps, and
Category 5 for connections that operate at 100 Mbps.
2.Make sure each twisted-pair cable does not exceed 100
meters (328 feet).
Figure 2-3 Making LAN Connections
2-11
CHAPTER 2
2.4.3 Attach to Your Network Using Radio Signals
Install a wireless network adapter in each computer that will
be connected to the Internet or your local network via radio
signals.
Rotate both antennas on the back of the Gateway to the
desired position. Try to place the Gateway in a position that
is located in the center of your wireless network. Normally,
the higher you place the antenna, the better the performance
will be. Ensure that the Gateway's location provides optimal
reception throughout your home or office.
Computers equipped with a wireless adapter can communicate with each other as an independent wireless LAN by
configuring each computer to the same radio channel.
However, the Gateway can provide access to your
wired/wireless LAN or to the Internet for all wireless workstations. Each wireless PC in this network infrastructure can
talk to any computer in the wireless group via a radio link,
or access other computers or network resources in the wired
LAN infrastructure or over the Internet via the Gateway.
The wireless infrastructure configuration not only extends
the accessibility of wireless PCs to the wired LAN, but also
doubles the effective wireless transmission range for wireless PCs by re-transmitting incoming radio signals through
the Gateway.
A wireless infrastructure can be used for access to a central
database, or for connection between mobile workers, as
2-12

CHAPTER 2
2.4.4 Attach the Gateway to the Internet
If Internet services are provided through an xDSL or Cable
modem, use unshielded or shielded twisted-pair Ethernet
cable (Category 3 or greater) with RJ-45 plugs to connect
the broadband modem directly to the WAN port on the
Gateway. Use either straight-through or crossover cable
depending on the port type provided by the modem (see
Appendices "B. Cables"). For ISDN or PSTN service, attach
the access device to the RS232 serial port on the Gateway.
Figure 2-5. Making WAN Connections
Note:When connecting to the WAN port, use 100-ohm
Category 3, 4 or 5 shielded or unshielded twisted-pair
cable with RJ-45 connectors at both ends for all connections.
2-14
CHAPTER 2
2.4.5 Connect the Gateway to a Printer

CHAPTER3
CONFIGURING CLIENT TCP/IP
To access the Internet through the Gateway Broadband Router,
you must configure the network settings of the computers on
your LAN to use the same IP subnet as that defined for the
Gateway. The default network settings for the Gateway are:
IP Address: 192.168.2.1
Subnet Mask: 255.255.255.0
Note:These settings can be changed to fit your network
requirements, but you must first configure at least one
computer as described in Chapter 3 "Configuring
Client TCP/IP" to access the Gateway's Web configuration interface. (See Chapter 4 "Configuring the
Gateway" for information on configuring the
Gateway.)
All PCs connected to the Gateway must be set to the same IP
subnet as the Gateway. The default subnet address of the
Gateway is 192.168.2.X (where X means 2-254) and the subnet
mask is 255.255.255.0. You can set the IP address for client PCs
either by automatically obtaining an IP address from the
Gateway's DHCP service or by manual configuration. See
Section 3.2 "Setting TCP/IP to Work with the Gateway".
