Wireless Placement and Range Guidelines
The range of your wireless connection can vary significantly based on the physical placement of
the wireless voice gateway. The latency, data throughput performance, and notebook power
consumption of wireless adapters also vary depending on your configuration choices.
For best results, place your wireless voice gateway:
• Near the center of the area in which your PCs will operate.
• In an elevated location such as a high shelf where the wirelessly connected PCs have line-ofsight access (even if through walls).
• Away from sources of interference, such as PCs, microwave ovens, and 2.4 GHz cordless
phones.
• Away from large metal surfaces.
• Put the antenna in a vertical position to provide the best side-to-side coverage. Put the antenna
in a horizontal position to provide the best up-and-down coverage.
• If using multiple access points, it is better if adjacent access points use different radio
frequency channels to reduce interference. The recommended channel spacing between
adjacent access points is 5 channels (for example, use channels 1 and 6, or 6 and 11).
The time it takes to establish a wireless connection can vary depending on both your security
settings and placement. WEP connections can take slightly longer to establish. Also, WEP
encryption can consume more battery power on a notebook computer.

On by default, the wireless voice gateway broadcasts its
SSID, allowing wireless stations that have a null (blank)
SSID to adopt the correct SSID. If you disable broadcast of
the SSID, only devices with the correct SSID can connect.
This nullifies the wireless network discovery feature of some
products such as Windows XP, but the data is still fully

Inbound and Outbound Rules
You can use firewall rules to block or allow specific traffic passing through from one side to the
other. Inbound rules (WAN to LAN) restrict access by outsiders to private resources, selectively
allowing only specific outside users to access specific resources. Outbound rules (LAN to WAN)
determine what outside resources local users can have access to.
A firewall has two default rules, one for inbound traffic and one for outbound. The default rules of
the gateway are:
• Inbound: Block all access from outside except responses to requests from the LAN side.
Instructions for setting up inbound rules can be found in “Port Forwarding” on page 3-10
• Outbound: Allow all access from the LAN side to the outside. Use Port Blocking to set up
outbound rules (see “Enabling or Disabling Content Filtering Services” on page 3-6).
You may define more rules that specify exceptions to the default rules. By adding custom rules,
you can block or allow access based on the service or application, source or destination IP
addresses, and time of day.

2. Click Delete.
Port Forwarding
You can use port forwarding to set up a rule that directs inbound traf fic for a particular service to a
local server (for example, a Web server or game server) based on the destination port. This makes
the server visible and available to the Internet.
Unless you set up port forwarding, the gateway prevents this type of traffic.The gateway uses
Network Address Translation (NAT). NAT presents a single IP address for your network to the
Internet. Outside users cannot directly address your local computers.
Note: Some residential broadband ISP accounts do not allow you to run any server
processes (such as a Web or FTP server) from your location. Your ISP may check
for servers and may suspend your account if it discovers active services at your
location. If you are unsure, refer to the acceptable use policy of your ISP.
Before setting up Port Forwarding, consider the following:
• If the IP address of the local server PC is assigned by DHCP, it may change when the PC is
rebooted. To avoid this, you can assign a static IP address to your server outside the range that
is assigned by DHCP, but in the same subnet as the rest of your LAN. By default, the IP
addresses in the range of 192.168.0.2 through 192.168.0.9 are reserved for this.
• Local computers must access the local server using the local LAN address of the computer
(192.168.0.XXX, by default). Attempts by local computers to access the server using the
external WAN IP address will fail.
Remember that allowing inbound services opens holes in your firewall. Only enable those ports
that are necessary for your network.

Port Triggering is an advanced feature that allows you to dynamical ly open inbound ports based on
outbound traffic on different ports. This feature can be used for gaming and other Internet
applications.
Note: Port Forwarding is similar to port triggering, but it is static and has some
limitations. Ports are open to traffic from the Internet until the port forwarding rule
is removed. Additionally, port forwarding does not work well for some
applications when your WAN IP address is assigned by DHCP, and is changed
frequently. Port Triggering opens an incoming port temporarily and does not
require the server on the internet to track your IP address if it is changed.
Port Triggering monitors outbo und traffic. When the gateway detects traffic on the specified
outbound port, it remembers the IP address of the computer that sent the data and “triggers” the
incoming port. Incoming traffic on the triggered port is then forwarded to the triggering computer.
For example, port triggering can be used for Internet Relay Chat (IRC). When you connect to an
IRC server, the server tries to connect back on the port to do an Ident lookup. Unless you have
configured Port Forwarding to open that port, the traffic will be blocked. In this example, the
initial login to the server in the range of ports is detected. This triggers the gateway to temporarily
forward the port to the PC that initiated the login.

Setting Up a DMZ Host
The Default DMZ Server feature is helpful when using some online games and video conferencing
applications that are incompatible with NAT. The gateway is programmed to recognize some of
these applications and to work properly with them, but there are other applications that may not
function well. In some cases, one local PC can run the application properly if that PC’s IP address
is entered as the Default DMZ Host.
Note: For security, you should avoid using the Default DMZ Server feature. When a
computer is designated as the default DMZ server, it loses much of the protection
of the firewall, and is exposed to many exploits from the Internet. If compromised,
the computer can be used to attack your network.
Incoming traffic from the Internet is normally discarded by the gateway unless the traffic is a
response to one of your local computers or a service that you have configured in the Port
Forwarding or Port Triggerin g screen. In stead of discarding this traffic, you can have it forwarded
to one computer on your network. This computer is called the default DMZ host.
To assign a computer or server to be a DMZ host:
1. From the main menu, under the Advanced heading, select DMZ Host. The DMZ Host screen
displays:
Figure 3-9
2. In the DMZ Address field, enter the IP address of the computer that you want to assign as a
DMZ host.
3. Click Apply.
To disable the DMZ host, enter 0 (zero), and then click Apply.
If you want the gateway to respond to a ping from the Internet, select the Respond to Ping on
WAN Port check box. This should only be used as a diagnostic tool, since it allows your gateway
to be discovered. Do not select this check box unless you have a specific reason to do so.

Using the Gateway as a DHCP Server
By default, the gateway is a DHCP server. It can assign IP, DNS server, and default gateway
addresses to all computers connected to the LAN. The default wireless voice gateway address is its
LAN address. The wireless voice gateway assigns IP addresses to the network computers from a
pool of addresses specified in the Starting Address and Ending Address fields. Each pool address
is tested before it is assigned to avoid duplicate addresses on the LAN.
Note: If another device on your network is the DHCP server, or if you will manually
configure the network settings of all of your computers, select No for the DHCP
Server. For more information about DHCP and IP addresses, see the link to
“Preparing a Computer for Network Access:” in Appendix B.

Universal Plug and Play (UPnP)
Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, access
the network and connect to other devices as needed. UPnP devices can automatically discover the
services from other registered UPnP devices on the network.
UPnP can be enabled or disabled for automatic device configuration. The default setting for UPnP
is disabled. If disabled, the router will not allow any device to automatically control the resources,
such as port forwarding (mapping), of the router.
Other features of UPnP:
• Advertisement Period. The number entered in this field (in minutes) determines how often
the router will advertise (broadcast) its UPnP information. This value can range from 1 to 1440
minutes. The default period is for 30 minutes.
– Shorter durations ensure that control points have current device status at the expense of
additional network traffic.
– Longer durations might compromise the freshness of the device status but can
significantly reduce network traffic.
• Advertisement Time To Live. The time to live for the advertisement is measured in hops
(steps) for each UPnP packet sent. A hop is the number of steps allowed to propagate for each
UPnP advertisement before it disappears. The number of hops can range from 1 to 255. The
default value for the advertisement time to live is 4 hops, which should be fine for most home
networks. If you notice that some devices are not being updated or reached correctly, then you
may need to increase this value a little.
• UPnP Portmap T able. The UPnP Portmap Table displays the IP address of each UPnP device
that is currently accessing the router and which ports (internal and external) that device has
opened. The UPnP Portmap Table also displays what type of port is opened and if that port is
still active for each IP address.

If the error persists, you have a hardware problem and should contact
technical support.
LAN LEDs are off, but ports
are connected.
Check the following:
• Make sure that the Ethernet cable connections are secure at the
gateway and at the hub or PC.
• Make sure that power is turned on to the connected computer.
• Be sure you are using the correct cable:
When connecting the gateway use the cable that was supplied.
Connecting to the Wireless Voice Gateway Main Menu
If you are unable to access the gateway’s main menu from a PC on your local network, check the
following:
• Check the Ethernet connection between the PC and the gateway as described in the previous
section.
• Make sure that your PC’s IP address is on the same subnet as the gateway. If you are using the
recommended addressing scheme, your PC’s address should be in the range of 192.168.0.10 to
192.168.0.254. Refer to “Preparing a Computer for Network Access:” in Appendix B for more
information about IP address configuration.
Note: If your PC’s IP address is shown as 169.254.x.x:
Recent versions of Windows and Mac OS generate and assign an IP address if
the computer cannot reach a DHCP server. These auto-generated addresses are
in the range of 169.254.x.x. If your IP address is in this range, check the
connection from the PC to the gateway and reboot your PC.

v1.0, February 2008
Wireless Cable Voice Gateway Model CBVG834G Adminstrators User Manual
• If your gateway’s IP address has been changed and you don’t know the current IP address,
clear the gateway’s configuration to factory defaults. This will set the gateway’s IP address to
192.168.0.1. This procedure is explained in “Restoring Factory Default Configuration
Settings” on page 4-5.
• Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using
Internet Explorer, click Refresh to be sure that the Java applet is loaded.
• Try quitting the browser and launching it again.
• Make sure that you are using the correct login information. The factory default login name is
admin and the password is password. Make sure that Caps Lock is off when entering this
information.
If the gateway does not save changes you have made, check the following:
• When entering configuration settings, be sure to click Apply before moving to another menu
or page, or your changes are lost.
• Click the Refresh or Reload button in the Web browser. The changes may have occurred, but
the Web browser may be caching the old configuration.
Troubleshooting the ISP Connection
If your gateway is unable to access the Internet and your Online LED is on, you might need to
register the Cable MAC Address and Device MAC Address of you gateway with your cable
service provider.
Additionally, your PC may not have the gateway configured as its TCP/IP gateway. If your PC
obtains its information from the gateway by DHCP, reboot the PC and verify the gateway address
as described in “Preparing a Computer for Network Access:” in Appendix B.
Troubleshooting a TCP/IP Network Using a Ping Utility
Most TCP/IP terminal devices and routers contain a ping utility that sends an echo request packet
to the designated device. The device then responds with an echo reply. Troubleshooting a TCP/IP
network is made easier by using the ping utility in your PC or workstation.
