Configuring Port Forwarding to Local Servers
Although the router causes your entire local network to appear as a single machine to the Internet,
you can make a local server (for example, a Web server or game server) visible and available to the
Internet. This is done using the Port Forwarding menu.
Use the Port Forwarding menu to configure the router to forward incoming protocols to computers
on your local network. In addition to servers for specific applications, you can also specify a
Default DMZ Server to which all other incoming protocols are forwarded. The DMZ Server is
configured in the WAN Setup menu as discussed in
“Configuring the WAN Setup Options” on
page 8-11
.
Before starting, you need to determine which type of service, application or game you will
provide, and the IP address of the computer that will provide the service. Be sure the computer’s IP
address never changes.
To configure port forwarding to a local server:
1.
From the main menu of the browser interface, under Advanced, click on
Port Forwarding /
Port Triggering
to view the port forwarding menu, shown below.
Note:
To assure that the same computer always has the same IP address, use the reserved
IP address feature of your WPNT834 router. See
“Using Address Reservation” on
page 8-15
for instructions on how to use reserved IP addresses.

2.
From the Service Name box, select the service or game that you will host on your network.
If the service does not appear in the list, see the following section,
Adding a Custom Service
.
3.
Enter the IP address of the local server in the corresponding Server IP Address box.
4.
Click the
Add
button.
Adding a Custom Service
To define a service, game or application that does not appear in the Service Name list, you must
determine what port numbers the service will use. For this information, you may need to contact
the manufacturer of the program that you wish to use. When you have the port number
information, follow these steps:
1.
Select
Port Forwarding / Port Triggering
from the Advanced Section of the main menu, as
described in the preceding section.
2.
Click the
Add Custom Service
button.
3.
Type the service name in the Service Name box.
4.
Type the beginning port number in the Starting Port box.
If the application uses only a single port; type the same port number in the Ending Port
box.
If the application uses a range of ports; type the ending port number of the range in the
Ending Port box.
5.
Type the IP address of the computer in the Server IP Address box.
6.
Click
Apply
to save your changes.

Editing or Deleting a Port Forwarding Entry
To edit or delete a Port Forwarding entry, follow these steps.

Click the
Edit Service
or
Delete Service
button.
Local Web and FTP Server Example
If a local computer with a private IP address of 192.168.1.33 acts as a Web and FTP server,
configure the Ports menu to forward HTTP (port 80) and FTP (port 21) to local address
192.168.1.33
In order for a remote user to access this server from the Internet, the remote user must know the IP
address that has been assigned by your ISP. If this address is 172.16.1.23, for example, an Internet
user can access your Web server by directing the browser to http://172.16.1.23. The assigned IP
address can be found in the Router Status Menu, where it is shown as the WAN IP Address.
Some considerations for this application are:
If your account’s IP address is assigned dynamically by your ISP, the IP address may change
periodically as the DHCP lease expires.
If the IP address of the local computer is assigned by DHCP, it may change when the computer
is rebooted. To avoid this, you can manually configure the computer to use a fixed address.
Local computers must access the local server using the computers’ local LAN address
(192.168.1.33 in this example). Attempts by local computers to access the server using the
external IP address (172.16.1.23 in this example) will fail.
Multiple Computers for Internet Gaming
To set up an additional computer to play Age of Empire or Quake III:
1.
Click the button of an unused port in the table.
2.
Select the game again from the Services/Games list.
3.
Change the beginning port number in the Start Port box.
For these games, use the supplied number in the default list and add +1 for each additional
computer. For example, if you have already configured one computer to play Hexen II (using
port 26900), the second computer's port number would be 26901, and the third computer
would be 26902.
4.
Type the same port number in the End Port box that you typed in the Start Port box.

5.
Type the IP address of the additional computer in the Server IP Address box.
6.
Click
Apply
.
Some online games and videoconferencing applications are incompatible with NAT. The
WPNT834 router 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
computer can run the application properly if that computer’s IP address is entered as the default in
the Port Forwarding / Port Triggering Menu. If one local computer acts as a game or
videoconferencing host, enter its IP address as the default.
Configuring the WAN Setup Options
The WAN Setup options let you configure a DMZ server, change the MTU size and enable the
wireless router to respond to a Ping on the WAN port. These options are discussed below.
Connecting Automatically, as Required
Normally, this option should be checked to enable it. An Internet connection will be made
automatically after each timeout, whenever Internet-bound traffic is detected. This provides
connection on demand and is potentially cost-saving, in some regions of Europe for example,
where Internet services charge by the minute.
If disabled, you must connect manually, using the “Connection Status” button on the Router Status
screen. This manual connection will stay up all the time without timeouts.
