External Components  
This section describes the back and front panels of the Wireless Gateway in details.  
Back Panel  
Following are explanations of the items on the Wireless Gateway's back panel:  
·
·
Antennae: The antennae at the back panel carry radio-frequency signals  
between wireless stations and the Wireless Gateway's wireless bridge (the  
interface between the wireless and wired parts of the LAN).  
Reset will be initiated when the reset button is pressed once and  
Reset button:  
the LPT LED begins to flash. Factory Reset will be initiated when the reset  
button is pressed continuously for three seconds or when the LPT LED begins  
to light up. Release the reset button and the LPT LED will begin to flash  
indicating the Wireless Gateway is changing to factory reset. When factory  
reset is completed the Wireless Gateway will be set to default on channel 11  
with default IP address as 192.168.0.254 and EES-ID is set as ‘ default’ .  
·
·
DC Input: For connection to the DC 5V power adapter.  
For connecting the Wireless Gateway to an upstream hub or  
Uplink port:  
switch with an ordinary “straight-through” (as opposed to cross-wired)  
Ethernet cable. This port and the LAN port next to it cannot be used at the  
same time; they are simply differently wired ports for LAN port 1.

Note: All connections to the Wireless Gateway's LAN ports  
should be made with Category 5 Ethernet cabling. Lower-grade  
cabling cannot reliably carry 100-Mbps signals.  
·
LAN ports 1 through 4: Switched, auto-negotiating 10/100-Mbps Ethernet  
ports for connecting end nodes (or downstream hub- or switched-based  
clusters of end nodes) to the Wireless Gateway.  
·
·
WAN port: 10-Mbps Ethernet port for connection to a DSL or cable modem  
or router.  
Parallel port: A Centronics-type connector for a standard printer cable.  
Front Panel  
The Wireless Gateway's LED indicators are located on the unit's front panel:  
·
·
Power: Illuminates whenever the unit has power.  
Wireless: Illuminates when the wireless AP (access point) is ready but idle;  
flashes when there is activity on the wireless link.  
·
·
LAN 1 to LAN 4 Link/Act: Each of these indicators illuminates when there is  
a good but idle link on the corresponding LAN port, flashes when packets are  
received/transmitted on the link.  
LAN 1 to LAN 4 100M: Each of these indicators illuminates when the  
corresponding LAN port is operating at 100 megabits per second.  
WAN Link: Illuminates when there is a good link on the WAN port.  
WAN Act: Illuminates whenever unit has power, flashes when there is  
activity on the WAN port.  
·
·
·
LPT: Flashes three times then goes off to indicate a successful Power-On  
Self-Test. Flashes on and off later during normal operation when there’ s  
printing activity. If the self-test detect any component error, thenthe LPT LED  
will continuously signal the error according to the following table. In the  
event of any such error signal, contact your dealer for correction of the faulty  
unit.

Web Configuration  
The Wireless Gateway must be configured through its built-in Web-based  
configuration utility. Before attempting to access this utility, note the following  
factory defaults:  
·
·
·
WAN interface defaults: IP address 192.168.100.254, address mask  
255.255.255.0. DHCP (Dynamic Host Configuration Protocol) client and  
PPPoE (Point-to-Point Protocol over Ethernet) functions are off.  
LAN interface defaults: IP address 192.168.0.254, address mask  
255.255.255.0. DHCP server function is on and will assign addresses in the  
range of 192.168.0.101 through 192.168.0.150.  
General defaults: No administrator password is set. Requests received  
through the WAN port (including “ping” requests and HTTP requests to the  
built-in Web-based configuration utility) are disabled.  
The requirements for configuring the Wireless Gateway are (1) a computer equipped  
with an Ethernet interface and a recent, frames-capable, Javascript-enabled World  
Wide Web browser, and (2) an Ethernet cable.  
You will also need extensive knowledge of the LAN and the broadband link that the  
Wireless Gateway will be connected to.  
The recommended way to connect the Wireless Gateway for configuration is as  
follows:  
1. Connect the computer to one of the LAN ports on the back panel of the  
Wireless Gateway's LAN ports with the Ethernet cable (NOT the uplink port).  
Do not make any other connections to the Wireless Gateway.  
2. Set the computer to use an IP address in the range of 192.168.0.1 through  
192.168.0.253 and an address mask of 255.255.255.0.  
10  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Note: If the operating system or the browser is set to use an  
HTTP proxy server, either turn off the setting or put the  
Wireless Gateway's IP address in the list of unproxied hosts.  
3. Power up the Wireless Gateway and wait about 15 seconds while it boots up.  
4. Command the browser to access the following URL:  
Note: If you have accessed the configuration utility and changed the IP address of  
the Wireless Gateway before, use the factory reset button to reset the unit. Or  
alternatively, you can enter the new IP address as the URL and make sure the  
computer use a corresponding IP address. For example, if you have changed the  
IP address to 172.16.100.1, use it as the URL and make sure the computer have an  
IP address in the range of 172.16.100.2 through 172.16.100.254. In addition, if  
you have changed the subnet mask, the computer must have the same subnet mask  
too.  
The configuration utility's initial display will appear and divide the browser window  
into three sections:  
·
·
·
A
at the top of the window contains the names of the utility's  
menu bar  
top-level menus. This bar never changes.  
A
at the left edge of the window contains the commands in  
occupying the rest of the window contains either buttons,  
command panel  
the current menu.  
A
settings panel  
input boxes, and other controls for changing device settings, or information  
about the Wireless Gateway.  
The following sections explain the items in the settings panels under each of the  
configuration utility's menus.

Basic Setup  
The settings panels under the Basic Setup menu contain settings that almost always  
must be adjusted to let the Wireless Gateway operate at all. Four settings panels can  
be accessed from the Basic Setup menu:

Basic Setup — Broadband Router  
The Basic Setup menu's Broadband Router panel is the first to appear whenever the  
configuration utility starts up. The controls in this panel are explained below.  
Router Name  
The Router Name is a text string that some ISPs require as a means of  
identification. The setting is ignored if the ISP does not require it. It is most  
often required on DHCP-based links, where it is sometimes referred to as the  
DHCP client's (that is, the Wireless Gateway's) “host name.” If the ISP  
requires this item, click in the Router Name input box and enter the correct  
name as shown in the materials received from the ISP.  
Local LAN  
13  
Download from Www.Somanuals.com. All Manuals Search And Download.  
The Local LAN settings are the IP address and subnet mask that will identify  
the Wireless Gateway to the other machines on your LAN. The address must  
be unique on the LAN, that is, assigned exclusively to the Wireless Gateway;  
the subnet mask must be the same for all machines on the LAN that will  
communicate directly with the Wireless Gateway. Be sure to keep a record  
of the address you set here. This will be the “default gateway” for other  
machines on the LAN.  
Before setting IP addresses, note that no machine must ever be assigned an  
address ending in zero (that is, x.x.x.0) or 255. An IP address ending in zero  
identifies an entire network, not a particular machine. An IP address ending in  
255 is a “broadcast” address, used for sending messages to all the machines on  
a network at the same time.  
Note also that possible subnet mask settings for the LAN interface are of the  
form 255.255.255.x, where x can be 0, 128, 192, 224, 240, 248, or 252. The  
installing technician will recognize that this makes the Local LAN settings  
suitable for a Class C IP network or a subnet of such a network.  
In the case that ISP give you a single globally legal IP address to be assigned  
to the Wireless Gateway's WAN port, you will have to use what are called  
“private addresses” on the LAN.  
An example of a private address is 172.16.0.0. This is a network address;  
individual machines on a LAN using this network address can be assigned  
addresses in the range of 172.16.0.1 through 172.16.0.254. (This assumes that  
all machines on the LAN use a subnet mask of 255.255.255.0; using any other  
mask requires extensive technical knowledge and is beyond the scope of this  
guide.)  
The following three IP address blocks have been set aside by Internet  
regulatory authorities specifically for local-only use:  
10.0.0.0 through 10.255.255.255  
172.16.0.0 through 172.31.255.255  
192.168.0.0 through 192.168.255.255  
Global WAN Mode  
14  
Download from Www.Somanuals.com. All Manuals Search And Download.  
The Global WAN Mode controls must be adjusted as required by your ISP.  
The settings you enter here determine how the Wireless Gateway will be  
identified to your ISP's equipment and other machines on the global Internet.  
·
·
·
If your ISP has given you a fixed IP address to use on the WAN link,  
click the Specify Global IP Address control. Then click in (or tab to)  
the three boxes below it and type in the global IP address, subnet mask,  
and default gateway that the ISP has instructed you to use.  
If your ISP will assign the Wireless Gateway an IP address and related  
settings using DHCP (the Dynamic Host Configuration Protocol),  
simply click Obtain Global IP Address Automatically (DHCP).  
DHCP is commonly used on cable links.  
If your ISP uses PPPoE (the Point-to-Point Protocol over Ethernet),  
click the PPP over Ethernet (PPPoE) control. The ISP will have  
given you a “username” or user ID and a password to use on the  
PPPoE link; click in (or tab to) the corresponding boxes under this  
control and type in the strings your ISP has instructed you to use. In  
some cases — especially if the Wireless Gateway's WAN port is  
networked directly to more than one broadband modem or router —  
you will need to type an identifying string into the Service Name box.  
Your PPPoE link might allow you to save on connection charges by  
disconnecting when the link is not in use and reconnecting when  
someone on the LAN wants to access the Internet. If this is the case,  
you have the option of setting the Connect on Demand control to Yes  
or . If you click , you will have to use the  
No No  
and  
PPPoE Connect  
PPPoE Disconnect commands in the Tools menu to take the Wireless  
Gateway on line and off line. (You can, alternatively, use the Manager  
Server software to set a connection schedule; see the Manager Server  
manual for details.) If you click  
, be sure to set the  
Maximum Idle  
Yes  
Time control also. The Wireless Gateway will then automatically  
disconnect whenever the specified amount of time passes without  
anyone on the LAN accessing the Internet.  
DNS IP Addresses  
In almost all cases your ISP will provide you with the IP addresses of two or  
more DNS (Domain Name System) servers. Click in the boxes provided and  
type in the addresses carefully. If you set the Wireless Gateway up as a DHCP  
15  
Download from Www.Somanuals.com. All Manuals Search And Download.  
server for the machines on your LAN, it will pass the addresses to those  
machines as part of the automatic configuration process. (If the Wireless  
Gateway will not act as a DHCP server, you might need to set the DNS server  
addresses on each of the machines individually.)  
WAN Port MAC  
A MAC (Media Access Control) address is a globally unique identifier for an  
Ethernet interface. In cases where the Wireless Gateway is a replacement for a  
computer or router with an existing broadband connection to an ISP, you  
might need to make the Wireless Gateway use the same MAC address as the  
device it replaces.  
The original device should have a label with the device's MAC address printed  
on it. A MAC address is ordinarily written as twelve hexadecimal digits, with  
or without separating spaces — for example, 0080C82F8086, 0080C8 2F8086,  
or 00 80 C8 2F 80 86 (these are all different ways of writing the same address).  
Only the numbers 0 through 9 and the letters A through F can appear in a  
hexadecimal MAC address. Letters can be in upper or lower case;  
0080c82f8086 is the same as 0080C82F8086.  
Only if it is necessary to do so, click the Use New MAC Address button, and  
then click in the box provided and carefully type the original device's MAC  
address.  
Save/Cancel  
After making sure all settings in the Broadband Router panel are correct, click  
Save to store the settings in the Wireless Gateway's non-volatile memory. You  
can, alternatively, click Cancel (or simply exit the panel) to restore all settings  
in the panel to the values last saved to or retrieved from the Wireless Gateway.  
Note: If you have changed the IP address in the Wireless  
Gateway's Local LAN settings, be sure, after you click Save, to  
point your browser to the Wireless Gateway's new IP address  
before going on.  
This completes the basic setup of the Wireless Gateway as a router. You are now  
ready to carry out the basic setup of the Wireless Gateway's other important functions.

Basic Setup — Wireless AP  
The Wireless Gateway's “wireless AP” is the access point — the radio-frequency  
transmitting and receiving circuitry — through which wireless devices will  
communicate with your LAN's wired devices and the Internet. To begin setting up the  
wireless AP, click Wireless AP in the command panel at the left edge of your  
browser window (if the command does not appear there, click Basic Setupat the top  
of the window first).  
ESS-ID  
“ESS-ID” (or “ESSID”) stands for Extended Service Set ID. This is an  
identifier for the network segment made up of the Wireless Gateway's wireless  
AP and the wireless stations that will communicate with it. Click in the  
ESS-ID box and type any string up to 32 characters long (spaces, symbols,  
and punctuation are not allowed). The same string must be set as the ESS-ID  
on each wireless station that will use the Wireless Gateway as an access point.  
Wireless Channel  
A “channel” is a range of frequencies to be used in communication between an  
AP and wireless stations. The number of channels available on the Wireless  
Gateway depends on the regulatory region in which the unit was sold.  
17  
Download from Www.Somanuals.com. All Manuals Search And Download.  
If the Wireless Gateway is the only AP on your LAN, it does not matter which  
channel you set the unit to use; properly configured 802.11b wireless stations  
will find the correct channel automatically.  
Where there are multiple APs with overlapping coverage areas, channel  
assignment must be carefully planned. A good practice is to set the Wireless  
Gateway to use a channel five or more channels away from that of any other  
AP with a coverage area overlapping that of the Wireless Gateway. A  
common scheme is to use channels 1, 6, and 11, making sure that no two APs  
using the same channel have overlapping coverage areas.  
Tx Bit Rate  
The Tx (transmission) Bit Rate is the speed at which wireless stations and an  
AP communicate. The choices are 1, 2, 5.5, and11 Mbps (megabits per  
second), and Fully Automatic. The default setting is Fully Automatic. A  
setting of Fully Automatic allows stations and the AP to adjust their speed on  
the basis of signal strength and quality. A low, fixed setting might be used for  
maximum reliability or to discourage the use of high-bandwidth applications  
such as video and audio. A high, fixed setting will fasten the transmission  
speed and ensure that only stations very close to the AP will be able to  
communicate reliably with it.  
Save/Cancel  
After making sure all settings in the Wireless AP panel are correct, click  
Save  
to store the settings in the Wireless Gateway's non-volatile memory. You can,  
alternatively, click (or simply exit the panel) to restore all settings in  
Cancel  
the panel to the values last saved to or retrieved from the Wireless Gateway.

Basic Setup — Print Server  
To view and adjust the Wireless Gateway's print server settings, click Print Server in  
the command panel at the left edge of your browser window (if the command does not  
appear there, click Basic Setup at the top of the window first). Controls in the Print  
Server settings panel are explained below.  
Print Port  
The Print Port Speed control has two possible settings, High and Low. The  
default setting is High, which is preferable for most modern printers. Change  
the setting to Low only if your printer is antiquated and prints incorrectly at a  
High setting.  
TCP/IP  
The Print Server TCP/IP settings include the IP address and subnet mask used  
by the Wireless Gateway on the LAN. These are set through the Broadband  
Router settings panel and displayed in the Print Server panel for informational  
purposes only. The Print Server panel also shows the Raw Send Port, an  
unchangeable setting used by Microsoft Windows 2000 for network-based  
printing.  
AppleTalk  
19  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Machines running the Macintosh OS on your LAN can print on a PostScript  
printer attached to the Wireless Gateway. When such machines request  
information about network printers using the AppleTalk protocol, the Wireless  
Gateway will respond with the information shown in the Print Server panel.  
This information must be correct for successful printing.  
The Zone Name is a text string identifying a group of devices using  
AppleTalk on a LAN. These devices can be concentrated in one area or  
scattered throughout the network. Ordinarily an asterisk [*] initially appears in  
the Zone Name box; this can represent “the local zone” (whatever its name  
might be), or it can mean that no zones are configured. If AppleTalk zones are  
configured on the network, click in the Zone Name box and type the name of  
the zone you want the printer to belong to.  
Chooser Name is the name the Wireless Gateway will use for the printer  
when reporting its presence to machines running the Macintosh OS. The  
Wireless Gateway will construct a default name from the name given to the  
broadband router in basic setup, but you can change it to any text string you  
like.  
The Printer Type is a text string that tells the Macintosh which driver to use  
for the printer. For a PostScript printer this should almost always be  
LaserWriter. This is the default value.  
The PostScript Level can be 1 or 2. Unless the printer is a very old model, a  
setting of Level 2 should work best.  
The  
setting tells the Macintosh how many PostScript fonts the  
Font Group  
printer has built in. All but the oldest PostScript printers can safely be assumed  
to have the “Standard 35” PostScript fonts.  
Save/Cancel  
After making sure all settings in the Print Server panel are correct, click Save  
to store the settings in the Wireless Gateway's non-volatile memory. You can,  
alternatively, click Cancel (or simply exit the panel) to restore all settings in  
the panel to the values last saved to or retrieved from the Wireless Gateway.

Basic Setup — Admin Password  
It is highly recommended that you set an administrator password on the Wireless  
Gateway as soon as possible to prevent any tampering with the device's settings. To  
do this, click Admin Password in the command panel at the left edge of your browser  
window (if the command does not appear there, click Basic Setup at the top of the  
window first).  
Set a password as follows:  
1. Click in the Password box and type the desired password. The password  
should not contain spaces, symbols, or punctuation marks. Note that only  
asterisks will appear as you type.  
2. Click in (or tab to) the Confirm Againbox and type exactly the same string.  
You can clear all input and start again, if you wish, by clicking the Cancel  
button.  
3. Click the Save button.  
The password will be stored in the Wireless Gateway's non-volatile memory and take  
effect immediately.

Advanced Settings  
Basic setup ensures that the Wireless Gateway will work with your ISP's equipment,  
your wireless stations, and your printer. Further adjustments are usually necessary to  
provide more sophisticated functions that may by desired or required on the local  
network. Such adjustments are carried out through the settings panels under the  
Advanced Settings menu. Those panels are:

Advanced Settings — DHCP Server  
The Wireless Gateway can act as a DHCP (Dynamic Host Configuration Protocol)  
server for machines on your LAN. It is a way to use private addresses in the LAN  
when your ISP does not offer you enough globally legal IP addresses. This function is  
turned on by default when the Wireless Gateway is first shipped or a factory reset is  
carried out.  
A DHCP server assigns IP addresses to stations on the LAN that are set up as DHCP  
clients. See your operating system manuals for instructions on setting up stations as  
DHCP clients. Each client will broadcast a request for configuration information upon  
power-up. The server will then respond, providing an IP address and other TCP/IP  
networking settings. You should not have more than one DHCP server on the LAN.  
To view the Wireless Gateway's DHCP server settings, click DHCP Serverin the  
command panel at the left edge of your browser window (if the command does not  
appear there, click Advanced Settings at the top of the window first). The DHCP  
Server settings panel will appear. The controls in this panel are explained below.

Enable  
Click No to turn the Wireless Gateway's DHCP server function off, or click  
to turn the function on. If you turn this function off, you can go directly to  
Yes  
the bottom of the panel and click Save, ignoring the rest of the controls in the  
panel; they will have no effect on the Wireless Gateway's operation.  
Address Range  
The Address Range is the pool of addresses from which the Wireless Gateway  
will assign addresses to DHCP clients on the LAN. The From control sets the  
lowest address in this range, and the To control sets the highest. Be careful  
24  
Download from Www.Somanuals.com. All Manuals Search And Download.  
that the range of addresses must not contain the IP address you have already  
given to the Wireless Gateway.  
The From and To addresses always begin with the same three numbers as the  
Wireless Gateway's Local LAN address (see “Broadband Router” under  
“Basic Setup,” above). Only the last number of each address can be changed  
through the DHCP Server settings panel. These two numbers are referred to  
below as the “From value” and the “To value.”  
The default From and To values are 101 and 150, respectively. These values  
are suitable for the Wireless Gateway's default Local LAN settings or settings  
similar to them — that is, settings that put the Wireless Gateway's LAN  
interface on an undivided Class C IP network, where valid host addresses run  
from x.x.x.1 to x.x.x.254. If the LAN interface is on a smaller network — that  
is, if a Local LAN subnet mask other than 255.255.255.0 is chosen — and the  
Wireless Gateway's DHCP server function is enabled, the DHCP address  
range must be adjusted accordingly.  
Lease Time  
The Lease Time value is the number of minutes each DHCP client can use its  
assigned IP address without requesting renewal from the Wireless Gateway.  
The default setting is 1440 minutes (24 hours). If a DHCP client does not  
request a lease renewal within this time, it is considered to have gone off the  
network, and its IP address can be assigned to another client. Note that some  
DHCP clients will themselves disconnect from the network if their lease time  
runs out and the DHCP server is not available to renew the lease.  
Reserve Table  
The Reserve Table lets youmake sure that when the DHCP server function is  
enabled, the Wireless Gateway will always assign certain IP addresses to  
certain DHCP clients and never to any others. This function is especially  
useful when, for example, there’ s a network print server which will be easier  
to use with a fixed IP address in the LAN. The Reserve Table can contain up  
to sixteen entries.  
To reserve an IP address for a DHCP client, you must know the client  
machine's MAC (Media Access Control) address. This is usually printed on a  
label affixed to the machine or its network interface card, and consists of  
25

twelve hexadecimal digits with or without spaces in between. The  
hexadecimal digits are 0 through 9 and A through F (in upper or lower case);  
0080C82F8086, 0080c82f8086, 0080C8 2F8086, and 00 80 C8 2F 80 86 are  
all different ways of writing the same MAC address.  
To enter a MAC address in the Reserve Table, click in a table entry's MAC  
Address box and type the address in, with or without spaces.  
The first three numbers of the Local IP address are automatically set to those  
of the Wireless Gateway's Local LAN address; for the fourth number, click in  
the box provided and type a suitable value.  
Save/Cancel  
After making sure all settings in the DHCP Server panel are correct, click  
Save to store the settings in the Wireless Gateway's non-volatile memory. You

Advanced Settings — Port Forwarding  
A TCP “port” is a number associated with a protocol providing a specific service. The  
source and destination port numbers are the first parts of a TCP packet.  
Port forwarding is often used in conjunction with Network Address Translation  
(NAT). When you use NAT, your LAN appears to the rest of the world to be a single  
machine with the IP address of the Wireless Gateway's WAN port. Requests from  
outside your LAN will all be directed to this address. Port forwarding is a means of  
using TCP packets' destination port number to determine which machine on the LAN  
each such request should be passed to.  
In short, port forwarding lets you provide TCP-borne services such as FTP (the File  
Transfer Protocol) and HTTP (the Hypertext Transfer Protocol of the World Wide  
Web) to machines outside your LAN even if your servers' IP addresses are hidden  
from those machines.  
To view the Port Forwarding settings panel, click Port Forwarding in the command  
panel at the left edge of your browser window (if the command does not appear there,  
click Advanced Settings at the top of the window first). The Port Forwarding settings  
panel will appear. The controls in this panel are explained below.

TCP Port to IP Forwarding  
This is a table of up to sixteen entries. A list of standard, commonly used TCP  
port numbers appears next to the table to help you create entries. Each entry  
consists of the port number for the protocol on which a particular  
(1)  
network-based service is based, and (2) the IP address of the server on your  
LAN that will provide that service to machines outside the LAN.  
To create an entry, fill in the TCP port number and type in the fourth number  
of the local IP address associated with it (the first three numbers are  
automatically set to those of the Wireless Gateway's Local LAN address; see  
“Broadband Router” under “Basic Setup,” above).  
To remove an entry, set the TCP port number or the local IP address, or both,  
to zero.

DMZ Host  
A DMZ host is a machine exposed to the Internet and running software  
designed to provide specific services while protecting the LAN's other  
machines from direct access from outside. On the Wireless Gateway, if an IP  
address for a DMZ host is specified, incoming packets of types not listed in  
the TCP Port to IP Forwarding table will be directed to the DMZ host.  
The first three numbers of the DMZ Host IP Address control are  
automatically set to those of the Wireless Gateway's Local LAN address (see  
“Broadband Router” under “Basic Setup,” above). The default value of the  
fourth number is zero; this has the effect of disabling the Wireless Gateway's  
DMZ Host function. If a DMZ host exists on the LAN, click in the box for the  
fourth number and type the last number of that machine's IP address.  
Save/Cancel  
After making sure all settings in the Port Forwarding settings panel are correct,

Advanced Settings — Port Open  
The Port Open function is provided mainly to facilitate controlled Internet gaming. It  
lets you specify the TCP ports that are used for input and output by up to sixteen  
applications. When the function is enabled for application, the Wireless Gateway will  
allow packets for the specified ports only (and none for any other ports) to pass  
between the WAN and the machine on the LAN that started the packet exchange.  
The controls in the Port Open settings panel are explained below.  
Enable  
You can turn the function on or off at any time by clicking the Enable control's  
Yes or No button.  
Go to  
You can define Port Open settings for up to sixteen applications. The current  
settings for application #1 are automatically displayed when the Port Open  
panel first appears. To view or input settings for another application, click a  
number here.  
Application  
30  
Download from Www.Somanuals.com. All Manuals Search And Download.  
The Application section of the Port Open settings panel contains a number, a  
Name input box, and Save and Cancel buttons.  
The number is the number of the application for which Port Open settings  
currently appear (see “Go to,” above).  
The Name box helps you identify the application that the displayed settings  
are for. To enter a name, click in this box and type any text up to 32 characters  
long. Spaces and punctuation can be used. The name serves only as a reminder;  
it does not affect operation in any way.  
The Save and Cancel buttons work slightly differently from those in other  
settings panels. They affect only the Enable setting and the contents of the  
Name input box. Click Save to store these settings (but not those in the Define  
Port Open List section of the panel) in the Wireless Gateway's non-volatile  
memory; click Cancel to restore them to the values last saved to or retrieved  
from the Wireless Gateway.  
Define Port Open List  
For the Port Open function to work, the Wireless Gateway must “know”  
which port or ports an application uses for input from the WAN (and, in some  
cases, output from the user's machine to the WAN). The Define Port Open List  
section of the Port Open settings panel lets you list the port or ports an  
application uses for input and output.  
An application might use a single port for all input and output, or a different  
port in each direction, or multiple ports (contiguous or non-contiguous) in one  
direction or both. The Define Open Port List section of the Port Open settings  
panel lets you input settings for all patterns of port use, from the simplest to  
the most complex. The controls in this section are explained below.  
The I/O control can be set to In or Out. This setting has no immediate effect.  
Its effect comes when you click Add to store Start Port and End Port numbers  
in the Wireless Gateway's non-volatile memory. If the I/O control is set to In,  
the specified port or ports will be treated by the Wireless Gateway as input  
ports; if it is set to Out, they will be treated as output ports.  
The Start Port and End Port boxes are for specifying a port or a range of  
ports. To specify a single port, click and type the same number into both boxes;  
31  
Download from Www.Somanuals.com. All Manuals Search And Download.  
to specify a range, click the Start Port box and type the lowest number of the  
range, and then click in the End Port box and type the highest number.  
The Add button is for sending the displayed I/O, Start Port, and End Port  
settings to the Wireless Gateway for storage in non-volatile memory. Once an  
entry has been added, it will appear in the drop-down list box titled (I/O, Start  
Port, End Port). You can repeat the process as many times as necessary to  
store complete port usage information for an application.  
The  
button is used in conjunction with the drop-down list box  
(I/O,  
Delete  
Start Port, End Port) to remove port usage settings previously saved in the  
non-volatile memory. (Note that in some browsers, the list box appears only  
after I/O, Start Port, and End Port settings have been saved with the Add  
button.) To delete an unwanted triplet of settings in  
(I/O, Start Port, and End  
Port), simply select those settings from the drop-down list and then click  
Delete.

Advanced Settings — Routing  
Routing settings determine whether the Wireless Gateway acts as a router, and how it  
interacts with other routers for efficient dispatching of packets to other networks.  
To view the Routing settings panel, click  
in the command panel at the left  
Routing  
edge of your browser window (if the command does not appear there, click Advanced  
at the top of the window first). The Routing settings panel will appear. The  
Settings  
controls in this panel are explained below.  
Static Routing  
33  
Download from Www.Somanuals.com. All Manuals Search And Download.  
A static route is a known, unchanging path from your LAN to another network  
or subnet. You can set up to sixteen static routes on the Wireless Gateway. A  
static route consists of the settings described below.  
IP Address: This is the IP network address of an outside network or subnet.  
When a machine on your LAN addresses a packet to any machine on this  
outside destination network, the Wireless Gateway will route that packet  
according to your Static Routing settings.  
Subnet Mask: A subnetmask is necessary for the above IP network address.  
Default Gateway: This is the IP address of the router or other gateway that  
can best handle packets addressed to the destination network or subnet. It must  
be a device on your LAN or on the network that the WAN port is connected  
to — that is, there must not be any intervening “hops” between the Wireless  
Gateway and the default gateway.  
Interface: The Interface control is a drop-down list box with two options:  
WAN and LAN. If the default gateway (see preceding) is networked to the  
WAN port, leave this control set to its default setting, WAN; if the default  
gateway is networked to one of the Wireless Gateway's LAN ports, set the  
Interface control to LAN.  
Dynamic Routing  
The Wireless Gateway can perform dynamic routing — that is, it can  
periodically exchange information with other routing devices to determine the  
best paths for outward-bound packets. These exchanges are in a form called  
the Routing Information Protocol (RIP). The Dynamic Routing section of the  
Routing settings panel lets you control RIP operation on the Wireless  
Gateway.  
The Yes and No options turn dynamic routing on and off, respectively. As a  
general rule, if a simple point-to-point connection to an ISP through the WAN  
port is the only link to networks other than the local LAN, dynamic routing  
should probably be turned off; otherwise, it might need to be turned on. The  
correct setting must be determined by a technician familiar with the  
networking environment in which the Wireless Gateway is installed. If a  
setting of No is chosen here, the remaining controls in the Dynamic Routing  
section have no effect.  
34  
Download from Www.Somanuals.com. All Manuals Search And Download.  
The LAN Interface settings control whether and how the Wireless Gateway  
uses RIP with any routing devices networked to it through its LAN ports.  
·
The TX setting controls the transmission of routing information to  
such devices. Possible settings are None (send no RIP packets), RIP-1  
(send RIP version 1 packets), RIP-1 Compatibility(send RIP version  
1 packets, but internally support RIP version 2 functions), and RIP-2  
(send RIP version 2 packets).  
·
The RX setting controls the handling of routing information received  
from such devices. Possible settings are None (ignore all RIP packets),  
RIP-1 only (accept only RIP version 1 packets), RIP-2 only (accept  
only RIP version 2 packets), and RIP-1/RIP-2 (accept both kinds of  
packets).  
The WAN Interface settings control whether and how the Wireless Gateway  
uses RIP with any routing devices networked to it through its WAN port. The  
available TX and RXsettings are the same as those for the LAN interface, and  
their effects are the same except that they control RIP use through the WAN  
port.  
NAT/Router Mode  
NAT stands for Network Address Translation. NAT is ordinarily used when  
only the WAN port has a “globally legal” IP address and machines on the  
LAN all use “private addresses.” In NAT operation, the Wireless Gateway  
modifies outgoing packets so their source IP address is that of the Wireless  
Gateway's WAN port. All machines on the LAN thus appear to be a single  
machine to outside devices. The Wireless Gateway also makes other necessary  
modifications of each outgoing packet, so that return packets can be directed  
to the correct machines on the LAN. Since all machines on the LAN appear to  
have the same IP address to outside devices, NAT operation is also known as  
“IP sharing.”  
NAT mode must be used when the machines on the LAN all use private  
addresses. It can also be used as a partial firewall when the machines on the  
LAN use globally legal IP addresses but no routing devices other than the  
Wireless Gateway exist on the LAN.

Advanced Settings — Filters  
The Filters settings panel can be used to ensure that certain machines on the LAN  
cannot access the WAN; to ensure that certain protocols cannot be used by anyone on  
the LAN to access the WAN; to keep certain packets from triggering an on-demand  
PPPoE connection; and to block all requests that originate on the WAN. The controls  
in this panel are described below.  
37  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Users Filter  
The Users Filter table lists machines on the LAN that are not allowed to access  
the WAN at all. There is room for sixteen entries. An entry can consist of an  
IP address or a MAC address, or both. (If both are entered, the Wireless  
Gateway will block all packets with either one, regardless of whether the other  
is associated with it.)  
The first three numbers of the Local IP Address control are automatically set  
to those of the Wireless Gateway's Local LAN address (see “Broadband  
Router” under “Basic Setup,” above). To enter a machine's IP address, click in  
the box for the fourth number and type the appropriate number. Make sure the  
machine you want to block always uses this IP address.  
If a machine does not have a fixed IP address, WAN access from that machine  
can still be blocked on the basis of the machine's MAC (Media Access Control)  
address. This is usually printed on a label affixed to the machine or its network  
interface card, and consists of twelve hexadecimal digits, possibly separated  
by spaces. The hexadecimal digits are 0 through 9 and A through F (in upper  
or lower case); 0080C82F8086, 0080c82f8086, 0080C8 2F8086, and 00 80 C8  
2F 80 86 are all different ways of writing the same address. To enter a  
machine's MAC address in the Users Filter table, find the address, click in a  
table entry's MAC Address box and type the address in.  
Protocols Filter  
38  
Download from Www.Somanuals.com. All Manuals Search And Download.  
The Protocols Filter control lets you list the TCP port numbers for up to  
sixteen protocols that you do not want LAN users to use over the WAN  
connection. A list of standard, commonly used TCP port numbers appears next  
to the table to help you create entries. To create an entry, simply click in a  
TCP Port # box and type a port number.  
NetBIOS over TCP/IP Filter  
NetBIOS is a communication protocol designed for use on small networks and  
heavily reliant on network-wide broadcasts. “NetBIOS over TCP/IP” (often  
abbreviated as NBT) is a means of letting NetBIOS requests travel between  
networks in TCP/IP packets. This method is used in Windows 95 and  
Windows NT.  
Since NetBIOS over TCP/IP can be routed between networks, it can trigger  
dial-out on a dial-on-demand PPPoE WAN connection (see “Global WAN  
Mode” under “Basic Setup — Broadband Router,” above). If you have a  
PPPoE link to your ISP, and the Connect on Demandcontrol is set to Yes,  
you will almost certainly need to enable the NetBIOS over TCP/IP filter.  
When the filter is enabled, NetBIOS over TCP/IP packets will not trigger  
dialing and will not be passed from the LAN to the WAN link. (NetBIOS over  
TCP/IP will still work among the machines on the LAN.)  
If the Wireless Gateway's WAN port connects a LAN to a corporate network  
containing resources that local machines must access using NetBIOS over  
TCP/IP, the NetBIOS over TCP/IP Filter control should be set to Disable to  
let those packets through.  
Block WAN Request  
The Block WAN Request function, if enabled, causes the Wireless Gateway to  
ignore requests addressed to it from the WAN. This makes the Wireless  
Gateway almost “invisible” to the outside world while still allowing access to  
the WAN from the LAN.  
Note that if the Block WAN Request function is enabled, outside machines  
will not be able to “ping” the Wireless Gateway and remote management of  
the Wireless Gateway will not be possible.

Advanced Settings — Manager Console  
A “manager console” is a computer running Manager Server, a program designed to  
enhance the capabilities of devices such as the Wireless Gateway and can be found in  
the DC-ROM that comes with the Wireless Gateway. All the features in the Manager  
Console panel require that such a computer be networked to the Wireless Gateway,  
preferably through the wired LAN or the wireless access point. In addition, this  
computer should be on and running Manager Server (which can run as a background  
process) all the time to take full advantage of manager console features.  
To set the Wireless Gateway up to work with a manager console, click Manager  
in the command panel at the left edge of your browser window (if the  
Console  
command does not appear there, click Advanced Settings at the top of the window  
first). The controls in the Manager Console panel are explained below.  
41  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Manager Console  
To communicate with a manager console, the Wireless Gateway must know  
the manager console's IP address. If you have set up a manager console, click  
in the IP Address box and type the address in.  
If no manager console exists, make sure the manager console IP Address  
control is set to 0.0.0.0 (this is the default setting). Any other setting will cause  
the Wireless Gateway to attempt to contact the manager console at regular  
intervals, adding unnecessarily to the network load.  
A manager console can be networked to the Wireless Gateway through the  
wired LAN, or the wireless access point. Since some manager console features  
need quick response times to work well, however, it is best for any manager  
console to be on the local LAN.  
Log and Filter  
The Wireless Gateway can send information about network activity to the  
manager console. Manager Server can keep a log of this information; it can  
also inspect the information as it is received and instruct the Wireless Gateway  
42  
Download from Www.Somanuals.com. All Manuals Search And Download.  
to filter (that is, bloc k) connections that meet criteria you set. For full details,  
see the Manager Server user's guide.  
The default setting of the Log and Filter control is Disable . This setting  
ensures that the Wireless Gateway will not send information about network  
activity to the manager console for logging or filtering. If you have set  
Manager Server to log or filter connections made through the Wireless  
Gateway, you must also set this panel's Log and Filter control to Enable for  
the function to work.  
Schedule Connection  
The Schedule Connection section of the Manager Console panel consists of a  
yes/no control, a schedule table, a holiday table, and a connect mode control.  
Using these controls, you can —  
·
·
·
·
set exact times at which the Wireless Gateway should (or may) connect  
to the WAN, and when it must disconnect, on each day of the week;  
specify days of the year on which the Wireless Gateway should not  
connect to the WAN;  
specify whether connection (during times when it is allowed by the  
tables) should be on-demand, continuous, or manually controlled;  
enable or disable the entire connection schedule.  
For the Schedule Connection feature to work correctly, the manager console's  
real-time clock must be set correctly, and the connection between the Wireless  
Gateway and the manager console must be reliable.  
The Yes/No control turns the Schedule Connection feature on and off. To use  
this control, simply click Yes or No, and then click the Save button at the  
bottom of the panel. Note that the Wireless Gateway will not connect to the  
WAN at all if this feature is turned on and no connection times are specified in  
the Schedule Table.  
The Schedule Table is for specifying times when the Wireless Gateway can  
or should connect to the WAN, and when it must disconnect, on each day of  
the week. There can be multiple connection periods per day. An input example  
above the table shows the correct format for each connection period: starting  
time, hypen, ending time, where the times always contain four digits each, are  
based on a 24-hour clock, and have a colon between the hour and the minute.  
43

Separate connection periods with commas; do not type any other characters,  
not even spaces.  
The Holiday Table is for specifying days of the year when the Wireless  
Gateway should not connect to the WAN at all. Click in the input box for the  
desired month and type the day or days of that month on which connection is  
not allowed. Use only a comma, never a space, between days.  
The Connect Mode control determines how connection to the WAN is  
triggered when it is allowed by the schedule:  
·
·
Connect on Demand means to connect when someone on the LAN  
tries to access the WAN;  
Auto Connect means to connect at the beginning of each specified  
connection period, leave the connection open for the whole period, and  
disconnect at the specified ending time;  
·
Manual Connect means to connect only on command from the  
manager.

Advanced Settings — Wireless Access  
The Wireless Access panel lets you control which machines can, and which ones  
cannot, connect to the network through the Wireless Gateway's wireless access point.  
Initially, no controls are placed on wireless access through the Wireless Gateway. To  
control access, you must create a “user list,” that is, a list of MAC (Media Access  
Control) addresses, each with an indication of whether the station with that address is  
allowed access or not. This list can then be enabled (that is, its restrictions put into  
effect) or disabled. Finally, you must indicate whether stations not on the list are  
allowed access or not.  
The controls in the Wireless Access panel are explained below.  
Define User List  
The Define User List section of the Wireless Access panel contains controls  
for creating and maintaining a list of wireless stations that are explicitly  
allowed or denied wireless access to the network.  
The MAC Address input box is for adding a station to the list. A station's  
MAC address can usually be found on a label attached to the station's case or  
its wireless interface card. It is a number in hexadecimal (base 16) notation,  
and may contain the letters A through F (in upper or lower case) as well as the  
digits 0 through 9. Spaces may be added for readability. An example of a  
45  
Download from Www.Somanuals.com. All Manuals Search And Download.  
MAC address is 0080C82F8086, which may also be written as 0080c82f8086,  
0080C8 2F8086, or 00 80 C8 2F 80 86. The first step in creating a User List  
entry is to click in the MAC Address input box and type the station's MAC  
address, with or without spaces.  
The Wireless Access control is for specifying whether the wireless station  
with the specified MAC address will be allowed access or not. Click Yes to  
allow access, No to deny it.  
The  
button stores the MAC Address and Wireless Access controls'  
Add  
settings in the Wireless Gateway's non-volatile memory.  
The Delete button is used in conjunction with the drop-down list box next to it.  
(Note that in some browsers, the list box appears only if there is at list one  
entry in the User List.) These two controls are for removing entries from the  
list. To remove an entry, open the list and click or drag to the unwanted entry;  
then click Delete.  
Access Control  
The Access Control section of the Wireless Access panel turns the User List  
on and off, and controls whether non-listed wireless stations are allowed  
access or not.  
The Enable/Disable control puts the User List into effect (“enables” it) or  
causes it to be ignored (“disables” it). Click the appropriate setting.  
The Other Users Wireless Access control determines whether unlisted  
wireless stations will be allowed access or not. Clicking Yes allows them  
access, clicking No denies it.  
The  
button stores the settings of the Enable/Disable and Other Users  
Save  
Wireless Access controls in the Wireless Gateway's non-volatile memory. The  
settings take effect immediately after being saved.

Advanced Settings — Wireless Encryption  
Wireless network communications are easily intercepted. WEP (Wired Equivalent  
Privacy) is an encryption method specified by the IEEE 802.11b standard to make any  
intercepted communications extremely difficult to interpret by unauthorized parties.  
The Wireless Gateway supports WEP with up to four “keys,” as specified in the  
standard. Each key can be of the 64-bit type or the 128-bit type.  
When WEP encryption is enabled on the Wireless Gateway, wireless access will be  
granted only to stations that also use WEP encryption with the same key as the  
Wireless Gateway.  
The recommended way to use WEP is as follows: (1) Decide on an input format and  
create four keys (key creation is explained below). (2) Select the key to be used (this  
must be done on the Wireless Gateway and all wireless stations communicating  
through it). (3) Enable WEP encryption.  
The controls in the Wireless Encryption panel are explained below.  
Enable/Disable  
The Enable/Disable control turns WEP encryption on and off on the Wireless  
Gateway. Click the desired setting. Any change in the setting takes effect  
when the settings in the Wireless Encryption panel are saved. For other

wireless devices to communicate through the Wireless Gateway, their  
encryption settings must be the same as the Wireless Gateway's.  
Input Format  
The Input Format control determines how your input for Key 1 through Key 4  
will be interpreted by the Wireless Gateway when you save the settings in the  
Wireless Encryption panel.  
Although your keys can be different lengths (that is, some can be 64-bit and  
some 128-bit), you must use the same input format (ASCII or hex) for all four  
keys.  
ASCII format causes each character you type to be interpreted as an eight-bit  
value. All unaccented upper- and lower-case Western European characters that  
can be input through your keyboard's typing zone are valid. For a 64-bit key,  
you must type 5 characters; for a 128-bit key, you must type 13 characters.  
These character counts result in bit counts of 40 and 104, respectively; the  
Wireless Gateway will automatically pad your input to a bit count of 64 or  
128.  
causes each pair of characters you type to be interpreted as an  
Hex format  
eight-bit value in hexadecimal (base 16) notation. Only the digits 0 through 9  
and the letters A through F (in upper or lower case) are valid. For a 64-bit key,  
you must type 10 pairs of characters; for a 128-bit key, you must type 26 pairs  
of characters. These character counts result in bit counts of 40 and 104,  
respectively; the Wireless Gateway will automatically pad your input to a bit  
count of 64 or 128.  
Key 1 through Key 4  
After deciding on an input format (see preceding), click in each key input box  
and type the key you have decided to use. To help maintain security, only  
asterisks will appear as you type. Remember to input the same keys on stations  
that will need to communicate through the Wireless Gateway's wireless access  
point.

This control determines which key the Wireless Gateway will use when WEP  
encryption is enabled. Click the list box to open it, and then drag to or click  
the name of the desired key.  
For good security, it is advisable to switch keys often. Remember to switch to  
the same key on both the Wireless Gateway and all wireless stations that need  
to communicate through it.

Advanced Settings — Wireless Bridge  
The “wireless bridge” is the circuitry tha t transfers packets between the wireless  
access point and wired connections. The purpose of the Wireless Bridge settings panel  
is to prevent specified kinds of packets from passing across this bridge. This may be  
done to increase network security or to avoid congestion on the wireless segment.  
To access the Wireless Bridge panel, click  
in the command panel at  
Wireless Bridge

Protocol Filters  
Protocol filters prevent specified kinds of packets from passing in either  
direction across the wireless bridge. The Protocol Filters section of the  
Wireless Bridge panel contains controls for turning this function on and off  
and for selecting the filter or filters you want to use.  
The Enable/Disable control is for turning the protocol filters that you have  
selected on and off. The default setting of this control is Disable , that is, any  
selected filters are off and no protocols are blocked.  
Common protocols are listed below the Enable/Disable control. (Numbers in  
hexadecimal notation appear to the right of several protocols. These are  
“protocol IDs,” for reference only.) To select or deselect a protocol, click the  
check box next to it. When a protocol is selected and the Enable/Disable  
control is set to Enable, that protocol will be filtered, that is, prevented from  
passing in either direction across the wireless bridge.  
The “Others to be Filtered” section lets you select protocols not listed by name.  
To select such a protocol, you must know its protocol ID (also known as the  
“Ethernet type,” “type element,” or “length element” code). To select a  
protocol in this way, click in a  
ID.

Broadcast/Multicast Filter  
51  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Unlike protocol filters, the Broadcast/Multicast Filter function is one-way: it  
prevents broadcast packets (those addressed to all stations on the network) and  
multicast packets (those addressed to two or more, but not all, stations) from  
passing through the wireless bridge from the wired segment to the wireless  
segment.  
Because of its (usually) lower speed and higher overhead, the wireless  
segment can become congested more easily than the wired segment. You can  
use the Broadcast/Multicast Filter function to reduce the possibility of  
congestion on the wireless segment. You can keep the wireless segment free  
of broadcasts and multicasts from all wired stations or from specified wired  
stations only.  
Broadcast packets are most often sent out in search of a server. The most  
common use of multicast packets is to deliver streaming audio and video. It is  
recommended that you use the Broadcast/Multicast Filter function only if your  
servers are all on the wired segment and you do not need to deliver streaming  
audio and video to wireless stations.  
The Enable/Disable control turns the Broadcast/Multicast Filter function on  
and off. The default setting is Disable , that is, the function is off, and  
broadcast and multicast packets can pass freely from the wired segment to the  
wireless segment.  
If Sent from All Wired Stations is selected and the Broadcast/Multicast  
Filter function is enabled, no broadcast or multicast packets from any wired  
station will be allowed onto the wireless segment.  
The Sent from Listed Wired Stations option lets you specify that only  
broadcast and multicast packets from particular wired stations are to be  
blocked at the wireless bridge.  
The MAC Address input boxes are for listing the wired stations from which  
broadcast and multicast packets should be blocked at the wireless bridge. You  
can list up to sixteen machines. A station's MAC address can usually be found  
on a label attached to the station's case or its network interface card. It is a  
number in hexadecimal (base 16) notation, and may contain the letters A  
through F (in upper or lower case) as well as the digits 0 through 9. Spaces  
may be added for readability. An example of a MAC address is  
0080C82F8086, which may also be written as 0080c82f8086, 0080C8 2F8086,

Information — Wireless Tallies  
The Wireless Tallies panelgives statistics on the operation of the Wireless Gateway's  
wireless access point. These statistics help you check wireless activity levels and  
monitor the health of the wireless segment.  
Figures are given for several kinds of transmitted (Tx) and received (Rx) frames.  
(“Frame,” in this context, can be interpreted to mean “packet”).  
Unicast frames are packets addressed to a single machine.  
Multicast frames are packets addressed to more than one machine. Packets addressed  
to all machines on the network, often called broadcast packets, are included in these  
tallies.  
Tx Errors is the number of packets transmitted erroneously.  
Rx FCS Errors is the number of packets received from wireless stations and found to  
have Frame Check Sequence errors. The FCS is a value computed by the sender on  
the basis of packet contents and then sent at the end of the packet. The Wireless  
Gateway does the same calculation and compares the result with the value received. A  
packet with an FCS error is silently dropped; the sender, receiving no  
acknowledgement, automatically tries again. An abnormally large number of FCS  
errors usually indicates radio-frequency interference or a faulty transmitter.

Rx Discards WEP Undecryptable is the number of packets dropped because the  
sender's WEP encryption settings differed from the Wireless Gateway's. Packets will  
be dropped if the devices use different keys or one device uses encryption and the  
other does not.
