introduction

hp digital home networking wireless gateway

Congratulations on your purchase of the HP Digital Home Networking Wireless

Gateway. The Wireless Gateway is the perfect solution for connecting your wireless

network to a high-speed broadband cable modem or Digital Subscriber Line (DSL)

Internet connection.

Your Gateway can be configured as a Dynamic Host Configuration Protocol

(DHCP) server, which means that it can automatically assign Internet Protocol (IP)

addresses to PCs in your Local Area Network (LAN). The Gateway becomes your

only visible network device on the Internet.

The Gateway also serves as your Internet firewall, protecting your networked PC’s

from access by external users. All incoming data is monitored and filtered using a

firewall. You can configure your Gateway to permit playing Internet games and

video conferencing. You also can use IP filtering to block your users from access to

the Internet as needed. Now all of your network users can enjoy fast broadband

Internet access and can share internal data.

A typical gateway (router) relies on a hub or switch to share its Internet connection,

but the HP Wireless Gateway, in addition to its wireless capabilities, also channels

the Internet connection through the full duplex speed of its built-in Ethernet 4-port

switch. This combination of wireless gateway and switch technology eliminates the

need to buy an additional hub or switch and extends the range of your wireless

network. Now your entire wireless network can enjoy fast broadband Internet

connections supported by its robust switched backbone. With the dual-function

speed and power of the Wireless Gateway, your network will operate faster than

you ever imagined.

reset button

To refresh Gateway connections and attempt to fix routing problems, very briefly

depress the Reset button with a paper clip.

If you have exhausted all troubleshooting options (see the Troubleshooting section of

this user’s guide) and continue to experience serious routing problems, depress the

Reset button for about five seconds to clear all of the Gateway data and restore

the factory default settings.

If the Gateway locks up, unplug the Power Adapter from the Gateway’s Power Port

for 3 to 5 seconds (but not longer) and then plug it back in. Leaving the power off

for too long could result in the loss of network connections.

Uplink Port You can connect a cable from another

switch, router, or hub to the Uplink port to

add it to your network. Since the Uplink

port shares wiring with LAN Port 4, port 4

will be disabled if a cable is plugged into

the Uplink port (and vice versa).

Power You will connect the included AC Power

Adapter to the Power port.

Antenna Jacks Connect the included antennas to the

antenna jacks.

Warning: Resetting the Gateway may create conflicts between your PC’s actual IP

addresses and what the Gateway expects them to be. You may be forced to restart the

entire system.

setting up a wireless network

network topology

A wireless Local Area Network (LAN) uses a wireless adapter to connect each

computer to the network. Computers in a wireless network must be configured to

share the same radio channel.

The Wireless USB Network Adapter provides wireless computers access to a wired

network. This integrated wireless and wired network is called an “infrastructure”

configuration. A group of wireless-network-adapter-equipped computers plus a

wireless access point, such as the HP Wireless Network Access Point, is called a

Basic Service Set (BSS). The wireless access point connects the wireless network to

the conventional wired network. Each wireless-adapter-equipped computer can

communicate with any computer in a wired network infrastructure via the wireless

access point.

An infrastructure configuration doubles the effective wireless transmission range of

two wireless-adapter-equipped PCs since the wireless access point forwards data

within the network. It is essential to use a unique ID (a BSSID, or simply, an SSID)

within a wireless network. All PCs within an independent wireless network that are

configured without roaming options (see Roaming below) must be configured with

the same wireless network ID.

The wireless network infrastructure configuration is appropriate for enterprise-scale

wireless access to a central database and for mobile users.

roaming

Infrastructure mode also supports roaming capabilities for mobile users. Multiple

wireless network can be configured as an “extended” wireless network, known as

an Extended Service Set (ESS), allowing users to roam freely within it. All wireless-

adapter-equipped PCs within one extended network must be configured with the

same extended network ID (an ESSID, or taken generically with a BSSID as

discussed above, often called an SSID,) and must use the same radio channel.

Before enabling an extended wireless network with roaming capability, select a

feasible radio channel and an optimal location for the wireless access point. Proper

wireless access point positioning and a clear radio signal will enhance

performance.

gateway system tray application

overview

The Gateway installation wizard installed an application on your computer that

functions as a tool kit for your Gateway. The application is accessed from a green,

red, or yellow house icon in the Windows System Tray. The Window System Tray is

in the recessed area of the Windows taskbar in the lower right of your screen.

If you did not authorize installation of the icon during Gateway installation, or if

you deleted the icon by choosing Exit from the pop-up menu, you can reinstall the

icon from the Windows Start menu. Click Start > Programs > HP Digital

Home Networking > Gateway System Tray Application. You can access

the System Tray application from any computer on your network.

The color of the house icon (green, red, or yellow) reflects the status of the network’s

Internet connection and your computer’s ability to communicate with the Gateway:

❑Green: all is well This computer is connected to the home network with an

active Internet connection.

❑Red: no Internet connection This computer is connected to the home

network, but there is no active Internet connection.

❑Yellow: connection to Gateway lost This computer is no longer

connected to the home network or to the Internet.

Besides providing constant feedback through the icon color, the Gateway System

Tray application provides additional functionality:

❑If there is any change in network status, a status notification window appears

on your screen describing the changed situation.

❑Right-click the Gateway System Tray icon to bring up a menu allowing you to

access the Gateway Control Panel, generate special status or diagnostic

reports, download and install software or firmware upgrades, and launch

additional Gateway utilities.

status notification windows

Any change in network status generates a status notification window describing the

change and, if needed, suggests actions to take. The change may also cause a

color change in the System Tray icon. (These same windows appear when you

select Get current network status from the System Tray pop-up menu. If all the results

are "ok", the utility has not detected any connection problems. If you do receive an

error message, however, see the table “Internet Connection Diagnostic” on

page 25 for more information.)

Note: This automatic notification feature is controlled by a toggle option in the

System Tray pop-up menu described in “Notify me when network events occur” on

page 27.

The following are examples of status notification windows, along with explanatory

comments (notice that the color of the house icon on the screen matches the color of

the icon on the System Tray):

frequently asked questions (FAQs)

gateway general information

What is Network Address Translation and what is it used for?

Network Address Translation (NAT) translates multiple IP addresses on the

private LAN to one public address that is sent out to the Internet. This adds a

level of network security since the addresses of PCs connected to the private

LAN are never transmitted over the Internet. NAT also allows the Gateway to be

used with low-cost Internet accounts, such as DSL or cable modem, where only

one Transmission Control Protocol/Internet Protocol (TCP/IP) address is

provided by the Internet Service Provider (ISP). The user may have 253 private

addresses behind this single address provided by the ISP.

What type of firewall does the Gateway have?

The Gateway uses NAT and TCP/IP port inspections.

Is the Gateway cross-platform compatible?

Any platform that supports Ethernet and TCP/IP is compatible with the

Gateway.

Does the Gateway replace a modem? Is there a cable or DSL modem in the

Gateway?

No, the Gateway must work in conjunction with a cable or DSL modem.

Which modems are compatible with the Gateway?

This Gateway is compatible with virtually any cable or DSL modem that

supports Ethernet.

How can I check whether I have static or DHCP IP Addresses?

Consult your ISP to obtain this information.

How do I get mIRC to work with the Gateway?

On the PC on which you are using mIRC, click the Forwarding tab on the

Expert Interface and set Port forwarding to 113 (see “forwarding” on

page 70 of the Appendix: Expert Interface). If you experience difficulty after

setting port forwarding, try changing the Direct Client-to-Client (DCC) settings to

a range from 1024 to 1030 on the DCC option of the Forwarding settings

wireless gateway

40

page of the Expert Interface.

How can I block corrupted FTP downloads?

If you are experiencing corrupted files when you download a file with your FTP

client, try using another FTP program.

What is DMZ Hosting?

Demilitarized zone (DMZ) hosting allows one IP address (or computer) to be

exposed to the Internet. Some applications require multiple TCP/IP ports to be

open. It is recommended that you set your computer with a static IP address if

you want to use DMZ Hosting.

If DMZ Hosting is used, does the exposed user/PC share the public IP address with

the Gateway?

No.

Does the Gateway pass PPTP packets or actively route PPTP sessions?

The Gateway allows Point-to-Point Tunneling Protocal (PPTP) packets to pass

through.

installation and configuration options

How many IP addresses can the Gateway support?

The Gateway supports a maximum of 253 IP addresses.

Where is the Gateway installed on the network?

In a typical environment, the Gateway is installed between the modem and the

LAN. Plug the Gateway into the cable or DSL modem's Ethernet port.

Does the Gateway support any operating system other than Windows 95, 98, Me,

2000, NT, or XP?

Yes, but Hewlett-Packard does not provide technical support for setup,

configuration, or troubleshooting of any non-Windows operating systems at this

time.

If all else fails in the installation, what can I do?

Reset the Gateway by depressing the Reset button for at least three seconds,

then reset your cable or DSL modem by powering the unit off and then back on.

Obtain and flash (upload) the latest firmware release from the Hewlett-Packard

Web site (www.hp.com).

Does the Gateway function in a Macintosh environment?

Yes, but the Gateway's setup pages are accessible only through Internet

Explorer v4.0 or Netscape Navigator v4.0 or higher for Macintosh PCs.

I cannot get the Web configuration screen for the Gateway. What can I do?

You may have forgotten to remove the proxy server settings on your Internet

browser, such as Netscape Navigator or Internet Explorer. Or, remove the dial-

up settings on your browser. Check your browser documentation.

Will the Gateway allow me to use my own public IP addresses and domain, or do I

have to use the IP addresses provided by the Gateway?

The Gateway mode allows customization of your public IP addresses and

domain.

How many ports can be simultaneously forwarded?

Theoretically, the Gateway can establish 520 sessions at the same time, but you

can only forward 10 ranges of ports.

installation and configuration options

43

What is the maximum number of virtual private network (VPN) sessions allowed by

the Gateway?

One VPN session at a time; the memory buffer on the Gateway is 512 KB.

My Web pages hang up, I get corrupted downloads, or junk characters are being

displayed on the screen. What do I do?

Force your Ethernet network interface card (NIC) to 10 Mbps or half duplex

mode and turn off the Autonegotiate feature temporarily (go to the Network

Control Panel in your Ethernet Adapter's Advanced Properties tab). Check with

your NIC manufacturer for more information.

supported software

Does the Gateway support ICQ send files?

Yes, with the following fix: from ICQ menu > preference > connections tab >,

select I am behind a firewall or proxy and set the firewall time-out to 80

seconds in the firewall setting. The Internet user can then send a file to a user

behind the Gateway.

How do I get Napster to work with the Gateway?

Napster is fully compatible with the Gateway. During installation select no

idea when asked about your firewall settings. Set your proxy settings to No

Proxy Server in File>Preferences.

I set up an Unreal Tournament server, but others on the network cannot join. What

do I do?

If you are running a dedicated Unreal Tournament (UT) server, you must create

a static IP address for each of the network PCs and forward ports 7777, 7778,

7779, 7780, 7781, and 27900 to the IP address of the server. If you want to

use the UT server admin, forward another port (8080 usually works well), then

in the [UWeb.WebServer] section of the server.ini file, set the ListenPort to 8080

to match the mapped port above and ServerName to the IP assigned to the

Gateway from your ISP.

Can multiple gamers on the LAN log on to one game server and play simultane-

ously with just one public IP address?

It depends on which network game you’re playing and what kind of game

server you’re using. For example, UT supports multi-login with just one public IP

address.

How do I get Half-Life:Team Fortress to work with the Gateway?

The default client port for Half-Life is 27005. The PCs on your LAN must have

“+clientport 2700x” in the HL shortcut command line; the x would be 6, 7, 8,

and on up. This allows multiple PCs to connect to the same server. One

exception: version 1.0.1.6 won't let multiple PCs with the same CD key connect

at the same time, even if they’re on the same LAN (it’s not a problem with

version 1.0.1.3). For hosting games, the HL server does not need to be in the

DMZ. Just forward port 27015 to the local IP of the server PC. There remains,

however, a problem with people being booted after a few minutes with an

illegible server message.

supported features

What are the advanced features of the Gateway?

The Gateway's advanced features include IP filtering, IP forwarding, dynamic

routing, static routing, DMZ hosting, and MAC address cloning.

Is IPSec Pass-Through supported by the EtherFast Gateway?

Yes, it is a built-in feature that the Gateway automatically enables.

Does the Gateway support IPX or AppleTalk?

No. TCP/IP is the only protocol standard for the Internet and has become the

global standard for communications. Internet Packet eXchange (IPX), a

NetWare communications protocol used only to route messages from one node

to another, and AppleTalk, a communications protocol used on Apple and

Macintosh networks, can be used from LAN to LAN connections, but those

protocols cannot connect from WAN to LAN.

Does the WAN connection of the Gateway support 100 Mbps Ethernet?

Since broadband Internet connections like cable and DSL do not exceed 10

Mbps, the Gateway’s current hardware design only supports 10 Mbps Ethernet

on its WAN port. It does support 100 Mbps through the built-in auto-sensing

Fast Ethernet 10/100 switch on the LAN side of the Gateway.

Does the Gateway support SPI?

Stateful packet inspection (SPI) is a new feature of the Gateway.

upgrade information

How will I be notified of new Gateway firmware upgrades?

All Hewlett-Packard firmware upgrades are posted on the HP website at

www.hp.com, where they can downloaded for free. The Gateway's firmware

can be upgraded with Trivial File Transfer Protocol (TFTP) programs. If your

Gateway’s Internet connection is working well, there is no need to download a

newer firmware version unless that version contains new features that you would

like to use. Downloading a more current version of Gateway firmware will not

enhance the quality or speed of your Internet connection, and may disrupt your

current connection stability.

troubleshooting

I can’t connect to the Gateway.

❑Verify that the Gateway is properly installed, the LAN connections are OK (the

LAN LEDs should be lit), and it is powered on.

❑Verify that the PC is using an IP address between 192.168.1.2 and

192.168.1.254 and thus compatible with the Gateway default IP address of

192.168.1.1.

❑The subnet mask must be set to 255.255.255.0 to match the Gateway’s subnet

mask. Confirm these settings for the Gateway from the Windows Start button

by selecting Settings > Control Panel > Network (or Network & Dial-

up Connections) > Local Area Connection > Internet Protocol

(TCP/IP)/Properties.

I can’t browse through the Gateway.

❑Verify that both ends of the Ethernet cable and power adapter are properly

connected and that the LEDs on the front panel are functioning properly.

❑If using Windows 98 or Me, verify the TCP/IP setup on the client side. Click the

Windows Start button, select Run, type winipcfg, and click Enter. The PC

should have an IP address of 192.168.1.xxx ("xxx" is from 2 to 254), the

subnet mask should be 255.255.255.0, the default gateway IP should be the

Gateway’s IP address, and it should have DNS. If using Windows 2000, use

ipconfig to obtain this information.

❑Also, check the same values as indicated in the previous bullet in the Setup tab

of the Gateway’s Expert Interface (see the Setup sections of the Appendix:

Expert Interface of this user’s guide.)

When I enter a URL or IP address, I get a Request timed out error.

❑Check to see if other PCs give you the same error message. If they do, verify

that your workstations’ IP settings are correct (IP address, subnet mask, default

gateway, and DNS server).

❑If the PCs are configured correctly but still not working, check the Gateway.

Verify that it is connected and powered on. Connect to the Gateway and check

its settings. If you cannot connect to it, check the LAN and power connections.

❑If the Gateway is configured correctly, check your Internet connection

(broadband modem) to see that it is working correctly.

❑Manually configure the TCP/IP with a DNS address provided by your ISP.

wireless gateway

50

I can’t obtain an IP address from my cable or DSL modem.

❑Verify that all of your cabling is properly connected and that the Gateway’s

WAN and LAN LEDs are lighting up.

❑Power down your cable or DSL modem for a few seconds, then turn it back on.

After the modem goes through its self-test, see if you now have an IP address.

❑Verify that your cable or DSL modem is DHCP-capable.

❑You may have to enter the host or domain name on the Setup page of the

Gateway’s Expert Interface. See “setup” on page 53 of the Appendix: Expert

Interface.

❑Your ISP may require MAC Addresses. Check with your ISP. This MAC address

can be obtained on the Status screen of the Gateway’s Expert Interface.

I can’t get a link to a modem, hub, or switch for one of my ports.

❑Verify that your cabling is undamaged and is connected properly.

❑Verify that your network interface adapter has been properly installed.

❑Verify that both the Gateway and the other device are powered on.

❑If you are linking to a hub or a switch, be sure that the other device is

functioning properly.

❑If you are connecting to a cable modem, try plugging it into the Gateway’s

uplink port rather than into a LAN port.

❑If all else fails, reset the Gateway by depressing the Reset button with a paper

clip. If you continue to experience serious routing problems, depressing the

Reset button for about five seconds will clear all of the Gateway data and

restore the factory default settings. However, be cautious before resetting the

Gateway since doing so risks creating conflicts between your PCs’ actual IP

addresses and what the Gateway expects them to be, and you may be forced

to restart the entire system.

I can’t access my e-mail or the Internet.

❑Some ISPs, especially cable providers, configure their networks so that you

don’t have to enter a full Internet address into your Web browser or e-mail

application to reach your home page or receive your e-mail.

❑You must obtain this information before connecting the Gateway to your

network: ask your ISP.

setting WEP encryption

Wired Equivalent Privacy (WEP) encryption is a method of encrypting data

transmitted over a wireless network to insure data security. In a wired network, data

security is maintained through the physical wire. WEP encryption provides the same

level of security for wireless data as if transmitted over standard network cabling.

In order to duplicate wired network security levels, wireless data is encrypted at the

point of transmission and decoded by the receiving device, allowing users to have

the same amount of security over their wireless network as they would over a wired

network. This level of security is in addition to that already provided by the

password protection of your network operating system.

The present standard for this encryption as set by the Institute of Electrical and

Electronics Engineers is defined as 40-bit (sometimes also called 64-bit) encryption.

These numbers refer to the complexity of the algorithms generated in order to code

and decode the data transmitted. The higher the bit number, the greater the

complexity of the algorithm and the more secure the encryption.

Higher levels of encryption often negatively affect network data transmission rates.

This encryption is not necessary for the operation of your wireless network device. If

ordinary password protection is sufficient, disregard WEP encryption. However, if

password prtection is not sufficient, then enable WEP encryption.

To enable WEP encryption:

1Click the Setup tab of the Expert Interface

2Select Enable under the Wireless field.

3Select Mandatory under the Wireless WEP field.

Note: WEP Encryption is an additional data security measure that is not

essential for Gateway operation.

dynamic routing

Dynamic routing allows the Gateway to automatically adjust to physical changes in

network layout. The Gateway, using the dynamic Routing Information Protocol (RIP)

protocol, determines the route that the network packets take based on the fewest

number of hops between source and destination. The RIP protocol regularly

broadcasts routing information to other routers on the network.

Select the Dyn. Routes tab of the Expert Interface to view the DYNAMIC

ROUTING screen.

To view the current routing table:

Click Show Routing Table to view all valid dynamic route entries in use.

the Internet connection.

2In the TX field, choose the protocol to transmit data on the network.

3In the RX field, choose the protocol to receive data from the network.

4Click Apply to save changes.

static routing

If your Gateway is connected to more than one network, it may be necessary to set

up a static route between them. Static routing determines the path that data follows

over your network before and after it passes through your Gateway. You can use

static routing to allow different IP domain users to access the Internet through this

device.

This Gateway is also capable of dynamic routing. To view the Dynamic Routing

screen, select the Dyn. Routes tab. In many cases, it is better to use dynamic

routing because it allows the Gateway to automatically adjust to physical changes

in the network layout. In order to use static routing, the Gateway's DHCP settings

must be disabled.

75

❑Destination LAN IP: Enter the IP address of the remote network or host for

which you wish to create a static route. If you are building a route to an

entire network set the network portion of the IP address to zero (0). For

example, the Gateway’s standard IP address is 192.168.1.1. Based on this

address, the address of the network to which the Gateway is connected is

192.168.1, with the last digit (1, in this case) determining the Gateway’s

place on the network. Enter 192.168.1.0 for the IP address if you want to

route to the Gateway’s entire network.

❑Subnet Mask: Enter the subnet mask used on the destination LAN's IP

domain. The subnet mask (also known as the network mask) identifies which

portion of an IP address is the network portion and which is the host

portion. For example, if the subnet mask is 255.255.255.0, the first three

numbers (255) identify this particular network, while the last digit (1 to 254)

identifies the specific host.

❑Default Gateway: If the Gateway is the main IP router to connect your

network to the Internet, then the default gateway IP address and your

Gateway IP address are the same. If you have another router handling your

network's Internet connection, enter the IP address of your main Internet

router here instead.

❑Hop Count: Specifies the number of nodes a data packet passes through

before reaching its destination. A node is any device on the network

(switches and PCs, for example).

❑Interface: Specifies whether your network is on the internal LAN or the

WAN (the Internet). Select one of the following:

❑LAN if you are connecting to a subnetwork.

❑WAN if you are connecting to a network through the Internet.

3Click Apply to save changes.

(each connected to the cable, not one to another).

wireless gateway

82

client/server network

Network in which one computer (the “server”) shares resources with other

computers, called “clients” (as opposed to a peer-to-peer network).

CSMA/CD (Carrier Sense Multiple Access/Collision Detect)

subnet.

DHCP (Dynamic Host Configuration Protocol)

A utility for assigning TCP/IP addresses to workstations automatically (a unique

IP address must be assigned to each computer in the network). When computers

are moved within the network, DHCP allows automated IP addresses to be

assigned automatically. DHCP “leases” an IP address to a device for a specific

amount of time, which is useful in education and other environments where

users change frequently. DHCP also supports static IP addresses for computers

needing a permanent IP address, such as those containing Web servers. See

static IP address.

DNS (Domain Name System)

Method for matching Internet domain names with IP addresses. When a

Uniform Resource Locator (URL) is entered into a Web browser, a domain name

server retrieves the corresponding IP address for the domain name specified

(“name resolution”) and sends the request to the appropriate server. Domain

names are convenient “handles” for IP addresses.

DSL (Digital Subscriber Line)

Transmits data bi-directionally at high speeds.

DSSS (Direct Sequence Spread Spectrum )

Generates a redundant bit pattern for each bit to be transmitted. This bit pattern

is called a chip (or chipping code). The longer the chip, the greater the

probability that the original data can be recovered. Even if one or more bits in

the chip are damaged during transmission, statistical techniques embedded in

the radio can recover the original data without the need for retransmission. To

an unintended receiver, DSSS appears as low-power wideband noise and is

rejected (ignored) by most narrowband receivers.

TCP/IP network, as opposed to a static IP address.

ESS (Extended Service Set)

More than one wireless network.

ESSID (Extended Service Set Identification)

A unique name (or ID) used by users roaming among the multiple wireless

networks. An infrastructure configuration can support roaming capability for

mobile workers. More than one BSS can be configured as an ESS. Users within

an ESS can roam freely between BSSs while served as a continuous connection

to the network. Wireless stations and wireless access points within an ESS must

be configured with the same ESSID and radio channel.
