Advanced Configuration of the Router

This chapter describes how to configure the advanced features of your RangeMax NEXT Wireless

Router Gigabit Edition Model WNR854T. These features can be found under the Advanced

heading in the Main Menu of the browser interface.

Configuring Port Triggering

Port Triggering is an advanced feature that can be used to easily enable gaming and other internet

applications. Port Forwarding is typically used to enable similar functionality, but it is static and

has some limitations.

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 by DHCP, for example.

Port Triggering monitors outbound traffic. When the router 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.

Using the Port Triggering page, you can make local computers or servers available to the Internet

for different services (for example, FTP or HTTP), to play Internet games (like Quake III), or to

use Internet applications (like CUseeMe).

Port Forwarding is designed for FTP, Web Server or other server based services. Once port

forwarding is set up, a request from the Internet will be forwarded to the proper server. In contrast,

port triggering will only allow request from Internet after a designated port is 'triggered'. Port

triggering applies to chat and Internet games.

Note:

If you use applications such as multi-player gaming, peer-to-peer connections, real

time communications such as instant messaging, or remote assistance (a feature in

Windows XP), you should also enable UPnP according to the instructions at

“Using Universal Plug and Play (UPnP)“ on page -17

.

•

Port Triggering Timeout

Enter a value up to 9999 minutes. The Port Triggering Timeout value controls the inactivity

timer for the designated inbound port(s). The inbound port(s) will be closed when the

inactivity timer expires.

•

For Internet Games or Applications

Before starting, you'll need to know which service, application or game you'll be configuring.

Also, you'll need to have the outbound port (triggering port) address for this game or

application.

Follow these steps to set up a computer to play Internet games or use Internet applications:

Note:

If the

Disable Port Triggering

box is checked after configuring port triggering,

port triggering will be disabled but any port triggering configuration information

you added to the router will be retained even though it will not be used.

Configuring for 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. From the Main Menu of the browser

interface, under Advanced, click on Port Forwarding to view the port forwarding menu, shown

below.

.

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 Security Menu.

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 each service. Be sure the computer’s IP

address never changes. To configure port forwarding to a local server:
