Using Push 'N' Connect (WPS) Wireless Setup  
Push 'N' Connect (WPS) can be a quick way to automatically set up your gateway’s wireless  
network and set up your wireless computer to connect to it at the same time. WPS, also  
called Wi-Fi Protected Setup, is relatively new technology, so before you decide to use it,  
check to make sure your wireless computers and devices support WPS. Look for the  
symbol on all the computers that will connect wirelessly to the gateway.  
If you do not see the  
symbol on all the computers that will connect to the wireless  
network, then you should manually set up your network first (see Manually Configuring  
Wireless Settings). After that, you can still use WPS to set up the wireless connection for the  
computers that support WPS.

Port Blocking  
You can use port blocking to block outbound traffic on specific ports. Outbound traffic rules  
control access to outside resources from local users.The default rule is to allow all access  
from the LAN side to the outside. You can use port blocking to add predefined or custom  
rules to specify exceptions to the default rule.  
Note: Any outbound traffic that is not blocked by rules that you have  
created is allowed by the default rule.  
To configure port blocking and services to block specific outbound traffic:  
1. In the main menu, under Advanced, select Port  
Blocking.  
2. In the Services field, select a service from the  
drop-down list. (For example, FTP, which uses

Wireless Cable Gateway CG3000D-1CXNAS  
Port Forwarding  
A firewall has default rules for inbound traffic (WAN to LAN) and for outbound traffic. Port  
forwarding affects the inbound rules. These rules restrict access from outsiders. By default,  
the gateway blocks access from outside except responses to requests from the LAN side.  
You can use port forwarding to add rules to specify exceptions to the default rule.  
Because the gateway uses Network Address Translation (NAT), your network presents only  
one IP address to the Internet, and outside users cannot directly address any of your local  
computers. However, by defining an inbound rule you can make a local server (for example, a  
web server or game server) or computer visible and available to the Internet. The rule tells  
the Gateway to direct inbound traffic for a particular service to one local server or computer  
based on the destination port number. This is also known as port forwarding.  
Some residential broadband ISPs do not allow you to run server processes (such as a Web  
or ftp server) from your location. Your ISP might check for servers and suspend your account  
if it finds active services at your location. See your ISP’s Acceptable Use policy.  
To configure port forwarding and services for specific inbound traffic:  
1. In the main menu, under Advanced, select Port Forwarding.  
2. In the Service field, select a service from the  
drop-down list. (For example, FTP, which uses  
TCP ports 20 and 21.)  
3. To add a custom rule that is not in the list of  
services, specify these settings in the Add  
Custom Rules table:  
Name. Enter a name for the service.  
Start Port. Enter the start port for the  
service.  
End Port.Enter the end port for the  
service.  
Protocol. Select the protocol for the ports:  
-
-
-
TCP. Select TCP only.  
UDP. Select UDP only.  
Both. Select both TCP and UDP.  
Local IP Address. Complete the local IP address for the computer that is using the  
service.  
4. Perform one of these actions:  
Click Add. The Active Forwarding Rules table displays the list of forwarded ports.  
To delete a service, select the radio button in the Active Forwarding Rules table for the  
service that you want to delete, and then click Delete.  
To reset the selection in the Services field and to clear all the fields in the Add  
Custom Rules table, click Reset.

Wireless Cable Gateway CG3000D-1CXNAS  
Considerations for Port Forwarding  
If the IP address of the local server PC is assigned by DHCP, it might 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 your LAN. By default, the  
IP addresses fromf 192.168.0.2 through 192.168.0.9 are reserved for this purpose.  
Local PCs must access the local server using the PCs’ local LAN address  
(192.168.0.XXX, by default). Attempts by local PCs to access the server using the  
external WAN IP address will fail.  
Port forwarding opens holes in your firewall. Only enable ports that are necessary.  
Port Triggering  
Port triggering is an advanced feature that you can use to allow gaming and other Internet  
applications that would otherwise be blocked by the firewall. You must know the port  
numbers that are used by the application. Port triggering operates as follows:  
1. A computer makes an outgoing connection using a port number defined in the Port  
Triggering table.  
2. The gateway records this connection, opens the incoming port or ports associated with this  
entry in the Port Triggering List, and associates them with the PC.  
3. The remote system receives the PCs request, and responds using a different port number.  
4. The gateway matches the response to the previous request, and forwards the response to  
the PC. (Without port triggering, this response would be treated as a new connection  
request rather than a response. As such, it would be handled in accordance with the port  
forwarding rules.)  
Note: Only one computer at a time can use port triggering. After a  
computer finishes using a port triggering application, there is a short  
time-out period before the application can be used by another PC.  
To configure port triggering:  
1. In the main menu, under Advanced, select Port Triggering.

Wireless Cable Gateway CG3000D-1CXNAS  
2. For each port trigger, enter the settings in the Port  
Trigger List:  
Trigger Range. To specify the range of  
outgoing ports that will be monitored to  
trigger the incoming port forwarding rule,  
enter the Start Port and End Port.  
Target Range. To specify the range of  
incoming ports that will be opened when  
triggered, enter the Start Port and End Port.  
Protocol. Select the protocol for the ports:  
3. Select the Enable checkbox for the port trigger.  
4. Perform one of the following actions:  
Click Apply to save your settings and  
activate the port triggers.  
To remove a port trigger, select it’s radio  
button and click Delete.  
To return all trigger and target ranges to zero, click Reset.  
DMZ Host  
You can use the DMZ Host screen to set up a default DMZ computer. Specifying a default  
DMZ computer allows you to set up a PC that is available to anyone on the Internet for  
services that you have not defined. There are security issues with doing this, so only set up  
the DMZ host if you are willing to risk open access. If you do not define a DMZ host the  
gateway discards any undefined service requests.  
To set up a DMZ host:  
1. In the main menu, under Advanced, select DMZ Host.  
2. If desired, select the Respond to Ping on WAN Port checkbox.  
3. Type the last digit(s) of the IP address in the DMZ Address field.

LAN IP Setup  
The LAN IP screen allows you to configure LAN services such as the IP address of the  
gateway and DHCP. The TCP/IP and DHCP default values work fine in most cases.  
Note: If you disable the DHCP server, you will need to assign to your  
computer a static IP address to reconnect to the gateway and  
enable the DHCP server again.  
To configure LAN IP settings:  
1. In the main menu, under Advanced, select  
LAN IP.  
2. Specify these settings:  
LAN IP Address: The factory default  
setting is 192.168.0.1.  
Subnet Mask: The network number  
portion of an IP address. Unless you  
are implementing subnetting, use  
255.255.255.0 as the subnet mask.  
DHCP Server: The Yes radio button is  
selected by default so the gateway acts  
as a DHCP server, providing the  
TCP/IP configuration for all the  
computers connected to it.  
If you will assign IP addresses  
manually, or you have another DHCP  
server on your network, select the No  
radio button.  
Starting IP Address and Ending IP  
Address: These fields specify the  
range in the IP address pool.  
Max Users: The maximum number of

Remote Management  
With remote management, you can allow a user or users on the Internet to configure,  
upgrade, and check the status of the gateway.  
Note: Use very secure passwords if you enable remote management.  
Passwords should contain no dictionary words from any language,  
and should be a mixture of letters (both upper and lower case),  
numbers, and symbols. Your password can be up to 16 characters.  
To manage this gateway through the Internet, you need its public IP Address, as seen from  
the Internet. This public IP address is allocated by your ISP. But if your ISP account uses a  
dynamic IP address, the address can change each time you connect to your ISP. There are  
two solutions to this problem:  
Have your ISP allocate you a fixed IP address.  
Use the DDNS (Dynamic DNS) feature so you can connect using a domain name, rather  
than an IP address.

Configuring 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. With  
UPnP you can specify:  
Advertisement Period. This specifies how often the gateway broadcasts its UPnP  
information. The default is 30 minutes. Lower numbers ensure that control points  
have current device status at the expense of additional network traffic. Larger  
numbers may compromise the freshness of the device status but can significantly  
reduce network traffic.  
Advertisement Time to Live. The time to live for the advertisement, measured in  
hops (steps) for each UPnP packet that is sent. A hop is the number of steps that are  
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, you might need to increase this value  
slightly.  
To configure UPnP:  
1. In the main menu, under Advanced, select UPnP.  
2. Select the Turn UPnP On check box. The  
default setting is disabled, which prevents  
the gateway from allowing any device to  
automatically control of its the resources,  
such as port forwarding.

If the path is not working correctly, you could have one of the following problems:  
Wrong physical connections.  
-
Make sure the LAN port LED is on. If the LED is off, see “Using LEDs to  
-
Check that the corresponding Link LEDs are on for your network interface card  
and for the hub ports (if any) that are connected to your workstation and gateway.  
Wrong network configuration.  
-
Verify that the Ethernet card driver software and TCP/IP software are both  
installed and configured on your PC or workstation.  
-
Verify that the IP address for your gateway and your workstation are correct and  
that the addresses are on the same subnet.  
Testing the Path from Your PC to a Remote Device  
After verifying that the LAN path works correctly, test the path from your PC to a remote  
device. From the Windows run menu, type:  
PING -n 10 <IP address>

Check that your PC has the IP address of your gateway listed as the default gateway. If  
the IP configuration of your PC is assigned by DHCP, this information will not be visible in  
your PC’s Network Control Panel. Verify that the IP address of the gateway is listed as the  
default gateway. See the link to the online document “Internet Networking and TCP/IP  
Check to see that the network address of your PC (the portion of the IP address specified  
by the netmask) is different from the network address of the remote device.  
Check that your Cable Link LED is on.  
If your ISP assigned a host name to your PC, enter that host name as the Account Name  
in the Basic Settings screen.  
Wireless Performance and Gateway Location  
The range of your wireless connection can vary significantly based on the physical placement  
of the 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 gateway according to the following guidelines:  
Near the center of the area in which your computers will operate.  
In an elevated location such as a high shelf where the wirelessly connected PCs have  
line-of-sight 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.  
To reduce interference when using more than one access point, NETGEAR  
recommends using 5 channel spacing between adjacent access points (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 the gateway location. WEP connections can take slightly longer to establish.  
Also, WEP encryption can consume more battery power on a notebook computer.
