Port Forwarding Settings

DMZ

DMZ (demilitarized zone) feature allows access to all ports. (For example, if you have problems hosting a game server, you

can choose this option. This will open all ports to your game server.)

1. Check the

Enable DMZ Host

box.

2. Type the IP address of the computer that you want to run the gaming application in the

DMZ IP Address

field.

3. Click

SUBMIT

button to activate the setting.

NOTE: Configuring the Wireless Broadband Router in DMZ mode is useful if you want to play certain games through

the Wireless Broadband Router, but the ports cannot be opened with all other existing configuration tools.

NOTICE: Opening a service to the Internet causes security concerns. Pay careful attention to security alerts,

and make sure that strong access controls and authentication are in place before allowing access to any

services.

Custom Port Forwarding Settings

Port Forwarding may be more difficult than DMZ to configure. However, it provides a relatively safe way of running a Internet

application or providing a Internet service from behind a firewall since only a single port (or a range of ports) is exposed to the

Internet. You can configure this port forwarding setting to create a custom rule that defines a specific port and protocol for data

traffic to pass through to the specific computer on your LAN.

An example is a HTTP server running on your LAN, which you want it to be available to the Internet. Your public IP address

(that your ISP gives you) is X.X.X.X (The X is a number), and you have a computer hosting the HTTP server at LAN address

192.168.2.2 on your Wireless Broadband Router (192.168.2.1) controlled LAN. You can configure 192.168.2.2 to have port

forwarding for port 80 (HTTP), then users on the Internet can go to http://X.X.X.X and get the HTTP server (192.168.2.2). The

data traffic entering service port 80 will be directed to the computer (192.168.2.2), and other computers on your LAN will not

see this data traffic.

For some internet applications (such as Internet messaging and gaming applications), you can configure this port forwarding

setting so that these applications can function correctly behind the firewall. These applications are required to have specific

TCP/UDP ports.

The ports for these applications and the protocol type will depend on what Internet services you are using.

Please check with your service provider or application's user manual to have the information first.

Make sure you have the following ports setup as described below.

1. Check the

Enable

box.

2. Enter the desired name or description in the

Service Name

field.

3. In the

Incoming Ports

field, enter a range of ports. If you want to specify only a single port number, enter the same

number in both boxes.

Port Triggering

Port triggering allows the router to watch outgoing data for specific port number. The IP address of the the computer that

sends the data is remembered by the router, so that when the requested data returns through the router, the data will be

passed to the specific computer by way of IP address and port mapping rules. The router opens the port when the Port

Triggering happens. When the computer running the application stops sending the data through this port, the router will close

the port.

1. Check the

Enable

box.

2. Enter the desired name or description in the

Application Name

field.

3. In the

Trigger Port

field, enter a port number. Check with your Internet application provider for more information on

what the Trigger Port it is using.

4. Select TCP (Transmission Control Protocol), or UDP (User Datagram Protocol), or both protocols as the

Trigger Port

Type

.

Static Routing

Static routes are manually configured routes to remote networks. That is, the route is predefined and is not discovered by the

Routing Information Protocol

(RIP), as in dynamic routing. Static routing allows you to assign a gateway to an IP address or

network. If there are routers on your internal network that do not function with RIP 1 or 2, you can set up a static route to those

routers.

The advantage to using static routing is that network traffic is reduced; thus, static routing is beneficial for slow Internet

connections. Routing using static routes is practical for small networks. For larger networks, the router needs to dynamically

keep track of changes in the physical wiring of the network, and the use of dynamic routing (RIP) is recommended.

NOTICE: The Static Routing settings are intended for advanced network administrators only. Do not change

these settings unless you are certain of the correct values. You may not be able to access the configuration

tool if invalid information is entered.

To use static routing, manually add the Destination IP Address, Subnet Mask, and Gateway IP Address for each route you are

adding to the Static Routing Table, and click

ADD

. If you are routing to an entire network, the last number in the destination IP

address should be a zero (0); for example, 192.168.0.0.

NOTE: In static routing, the Wireless Broadband Router does

NOT

dynamically discover routing information and does

NOT

use RIP. The Wireless Broadband Router currently does

NOT

support RIP.

Use the checkboxes beside each route and the

DELETE

button to remove static routes from the Static Routing Table.

Allow remote user to configure the device

If you would like a remote user to be able to administer your Wireless Broadband Router over the Internet, check

the box titled

Allow remote user to configure the device

. Enter the IP address for the remote administration

host computer.

Allow remote user to ping the device

Check the box

Allow remote user to ping the device

to enable your Wireless Broadband Router to be "ping"ed

by any user on the Internet. This feature is helpful if you want to let other Internet users to check the status of

your Wireless Broadband Router.

Enable UPnP function

UPnP stands for Universal Plug and Play, a protocol which allows UPnP-enabled client computers such as

Windows XP to discover and configure the Wireless Broadband Router. One of most common use of UPnP on

the router is to open ports to allow application-specific data to be forwarded through the router for various Internet

services or gaming applications. The router detection and the router configuration process can be carried out

automatically by the UPnP-enabled client applications such as

MSN Messenger

so you won't have to do it

manually. Check the

Enable UPnP function

box to enable this service or clear the box to disable it.

If you have an Windows XP system, you can use it to access and control the router while the router's UPnP

function is enabled. Here are some examples of what you can do with UPnP from your XP system.

Example 1

) Access the router's Web Configuration tool without knowing its IP address.

1. Double click on the "My Network Neighborhood" icon from the desktop.

2. Double click on the "Broadband Router" icon that is created for your router.

3. This will bring up the authentication screen of the router's Web configuration tool. Enter the correct

password and click

OK

to access the Web configuration tool.

Example 2 ) Manage the router's port forwarding rules from the XP interface.

NOTE: You have already configured a port forwarding rule for the service via the web configuration tool, you

don't need to perform the following steps for the same service again.

1. Right click on the "My Network Neighborhood" icon from the desktop.

2. Right click the

Internet Connection

icon created for the router. (See below)

Page 100 / 178

3. Right click the icon and select

Property

.

4. Click

Settings

.

5. Click

Add

.

6. Enter Description of service, IP address of the service host, External Port number for this service, Internal

Port number for this service and select either TCP or UDP.

For example, the graph below shows an example of how to enable a computer with an IP address

192.168.2.101 to host a public HTTP server.
