• The 2.4 GHz access point provides connectivity to 802.11b/g/n wireless clients that are
farther from the AP. Use this access point for legacy wireless clients.
Note: If you are connecting the wireless client to the 5 GHz access point, make
sure the wireless client supports 5 GHz connections.
Wireless Client
The wireless client allows you to connect a wireless client to a wireless access point. Both
built-in and external (for example via USB) wireless clients are available.
Devices like tablets, smart TVs and smartphones usually have a built-in wireless client. Check
the documentation of your device for more information.
Configuring Your Wireless Clients

Channel Width:
The channel bandwidth can be selected manually for Wireless-N connections. For best
performance in a network using Wireless-N, Wireless-G, and Wireless-B devices, it is
suggested to use the AUTO (20 or 40MHz) channel setting.
Wireless-N connections will use the 40MHz channel if there is no interference, while WirelessG and Wireless-B will still use the 20MHz channel.
For Wireless-G and Wireless-B networking only, select 20MHz only. Then, only the 20MHz
channel will be used.
For 5GHz, the options include AUTO 20 or 40 or 80MHz. The 80MHz will only be used for AC.
Channel:
If AUTO (20 or 40MHz) is selected for the Radio Band setting the appropriate Standard
Channel setting will be automatically selected, depending on the Wide Channel setting.
If only 20MHz is selected as the Radio Band setting, select the appropriate channel from the
list provided to correspond with the network settings. All devices in the wireless network must
broadcast on the same channel to communicate.
MAC Address: The wireless MAC Address is displayed in this field.
Scan Nearby AP: The Scan button provides a mechanism for the AP to scan for neighboring
APs and provides various statistics on neighbors.
Note: Enabling Network Name (SSID) broadcast does not mean that everyone
can connect to your network. They still need the correct wireless network key
(password) to connect to the Gateway network. It only informs them that your
network is present.

How to Start a WPS Session
Wi-Fi Protected Setup (WPS) allows users to easily connect to the wireless network by simply
pushing a button or entering a PIN code. WPS permits home users to easily connect to a
secure network without any complex configuration and eliminates the need to remember or
store their security information in an unsafe way.
The CGA4131 supports the WPS Push-Button Configuration (PBC). In this method, the user
pushes a button, either an actual or a virtual one, on both the access point and the new
wireless client device.
The CGA4131 provides two WPS PBC buttons:
• Hardware button on the front panel
• Software button on the Web UI
Pressing either PBC button on the CGA4131 will flash the WPS LED and initiate the WPS PBC
operation. Then, press the software PBC button on the client device (some clients use a
hardware button). The two buttons must be pushed within 60 seconds of each other.
Using the Admin Tool, click the Wireless tab and then click the WPS control tab. The screen
displays WPS setup information. Here a user can set and display WPS parameters including
the Access Point PIN and Connection Method (Push Button / PIN Number).

Port Configuration for Applications and Services
The Gateway allows you to use one Internet connection for multiple computers. This means
that all your computers share one public IP address, as if only one computer were connected
to the outside world.
Issue
When the Gateway receives an incoming message, the Gateway must decide to which
computer it should send this message. If the incoming message is a response to an outgoing
message originating from one of your computers, the Gateway sends the incoming message to
this computer.
Figure 30: Gateway Message Handling – Incoming Response to Outgoing Message
t
CGA4131 Business Gateway Setup and User Guide 40
Page 47
Advanced Configuration
The Gateway will not be able to resolve the destination if:
• The incoming message arrives on a different port as the outgoing message. The
Gateway will not know that the two messages are related.
• There is no outgoing message.
Figure 31: Gateway Message Handling – Incoming Message Arrives on a Different Port or
There is no Outgoing Message
Solutions
To avoid this problem, the Gateway offers the following solutions:
• The Gateway supports automatic device discovery and port configuration for UPnPenabled devices. For more information, see UPnP (Universal Plug and Play).
• The Gateway allows you to assign a port to a device. For more information, see Port
Forwarding.
• The Gateway allows you to define a number of trigger ports. When a device sends data
over one of these ports, the Gateway will automatically assign several related ports to the
device. For more information, see Port triggering.
UPnP (Universal Plug and Play)
UPnP is designed to automate the installation and configuration of a (small) network as much
as possible. This means that UPnP-capable devices can join and leave a network without any
effor t of a network admi nistrator.
CGA4131 Business Gateway Setup and User Guide 41
Page 48
Advanced Configuration
Supported Operating Systems
The following operating systems support UPnP:
• Windows 10
• Windows 8
• Windows 7
• Windows Vista
• Windows XP
Note: If your computer is running Windows XP, you first must install the UPnP
component. For more information, see Windows help.
UPnP and the Gateway
UPnP offers you the following functions:
• You do not have to manually create port mappings to run services on a computer. The
automatic port configuration mechanism for UPnP-enabled applications will do this for
you. If the application is UPnP- enabled, UPnP will create these entries automatically.
• You can access the Admin Tool without having to remember the address of the Gateway.
Enable UPnP on the Gateway
1. Go to the Admin Tool (http://192.168.0.1), using a computer or device that is currently
connected to your Gateway (either wired or wirelessly). For more information, see
Accessing the Admin Tool.
2. On the Application menu, click UPnP.

Port Forwarding
Port forwarding allows you to forward incoming Internet traffic arriving on a specific port to an
internal IP address. For example, if you are running a web server and the Gateway receives a
request on port 80, this request should be forwarded to your web server.
Use a Reserved IP Address
The target device of the port forwarding rules will be specified by an IP address. Make sure
that your device uses a fixed (static) IP address. If you do not do this, the device might get a
new IP address after some time and the port forwarding rule will no longer be applied to the
device. For more information, see “Assigning a reserved IP (static IP) to a device”.
Proceed as follows:
1. Go to the Admin Tool (http://192.168.0.1), using a computer or device that is currently
connected to your Gateway (either wired or wirelessly). For more information, see
Accessing the Admin Tool.
2. Click the Application tab and then the Port Forward subtab.
Result: The Port Forward screen appears. This screen displays Port Forward information
– Start Port, End Port, Type, Service IP, Service IPv6, Enable and Delete.
CGA4131 Business Gateway Setup and User Guide 43
Page 50
Advanced Configuration
Figure 34: Port Forward Table Settings
On this screen, you can select the range of ports and the types of traffic to be forwarded to an
IP address. The range information can be configured in Start Port and End Port fields. You
can select either TCP traffic alone or UDP traffic alone or both.
The Server IP should be the IP address of the target device. In the example above (Figure 34),
the 4131 is configured to forward TCP traffic on po rts 2-20 to IP address 192.168.0.10.
The enable button enables the port forwarding feature; the entries can be deleted from the
table clicking the X in the Delete column.
Port triggering
Port triggering allows you to define a set of dynamic port forwarding rules that will be activated
as soon as a device sends traffic to the Internet over a specific port(s), the trigger port(s).
The difference compared to the port forwarding function described in Getting Started is that:
• Port triggering rules will only be activated if a local device is sending traffic over one of
the trigger ports. There must be outbound traffic first.
• Port triggering rules forward the traffic to any device that has initiated the communication
while port forwarding only forwards to a specific fixed IP.
• Port triggering rules allow you to translate the port numbers. This means that the
incoming port can differ from the target port.
• If no outgoing traffic is detected on the Trigger Range ports for 10 minutes, the Target
Range ports will close.
This is a safer method for opening specific ports for special applications such as, video
conferencing programs, interactive gaming, file transfer in chat programs, etc. They are
dynamically triggered and not held open constantly or erroneously left open via the router
administrator and exposed for potential hackers to discover.

Figure 36: Port Filter Settings
Configure a DMZ Host
The DMZ feature exposes the network user to the Internet for using special-purpose services
such as Internet Gaming or Video Conferencing. DMZ hosting forwards all the ports at the
same time to one computer. The Port Forwarding feature is more secure because it only opens
the ports the user wants to have opened, while DMZ hosting opens all the ports of one
computer, exposing the computer to the Internet. This is generally used if PCs are running
specific applications that use random unknown port numbers and do not function correctly with
specific port triggers or port forwarding setups.
It is advisable not to have any PCs/Servers as DMZ hosts because of exposure to the public
Internet which results from this configuration. Remember to disable this setting if this is
enabled temporarily for any specific application.
Any computer whose port is being forwarded must have its DHCP client function disabled and
should have a static IP address assigned to it. Its IP address may change when it is using the
DHCP function.
Application Tab/DMZ
Click the Application tab then click the DMZ tab. This screen displays DMZ setup information.

Figure 37: DMZ Settings
Dynamic DNS
Dynamic DNS (DDNS) configures the Gateway's router functionality as a Dynamic DNS client.
Dynamic DNS allows a dynamic IP address to be aliased to a static, predefined host name so
that the host can be easily contacted by other hosts on the Internet, even if its IP address
changes. The CGA4131 supports a dynamic DNS client compatible with the Dynamic DNS
service (http://www.dyndns.com/).
1. Go to the Admin Tool (http://192.168.0.1), using a computer or device that is currently
connected to your Gateway (either wired or wirelessly). For more information, see

Figure 38: Dynamic DNS Settings
Assigning a Reserved IP (static IP) to a Device
By default, each device will get an IP address from the Gateway’s DHCP server. When a
device leaves, is turned off or the lease time of the address has expired, the IP address
becomes available and can be re-used for other devices.
When you want to run a service on a network device (for example, a web server, network
printer, etc.), it is advised to assign a “static IP” to the device. This way, the device will always
be reachable on the same address and there is no risk that you are accessing the wrong
device.
You can add a static IP through the LAN Setup screen. Click Connection and LAN to access
this screen and then click Add Static IP (see Figure 39).
