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.

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.  
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.  
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.

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.

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

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.

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.

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.

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.

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  
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  
Note: WEP Encryption is an additional data security measure that is not  
essential for Gateway operation.  
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:  
1 Click the Setup tab of the Expert Interface  
2 Select Enable under the Wireless field.  
3 Select Mandatory under the Wireless WEP field.

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.

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.  
Warning: This is an advanced feature. Please proceed with caution.  
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.

Download from Www.Somanuals.com. All Manuals Search And Download.  
advanced  
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.
