The Applications and Gaming Tab - Port Range Forward
The Applications and Gaming Tab allows you to set up public services on your network, such as web servers, ftp
servers, e-mail servers, or other specialized Internet applications. (Specialized Internet applications are any
applications that use Internet access to perform functions such as videoconferencing or online gaming. Some
Internet applications may not require any forwarding.)
To forward a port, enter the information on each line for the criteria required. Descriptions of each criteria are
described here.
Application. In this field, enter the name you wish to give the application. Each name can be up to 12 characters.
Start/End. This is the port range. Enter the number that starts the port range under Start and the number that
ends the range under End.
Protocol. Enter the protocol used for this application, either TCP or UDP, or Both.
IP Address. For each application, enter the IP Address of the PC running the specific application.
Enable. Click the Enable checkbox to enable port forwarding for the relevant application.

The Applications & Gaming Tab - Port Triggering

The Applications & Gaming Tab - Port Triggering
The Port Triggering screen allows the Router to watch outgoing data for specific port numbers. The IP address of
the computer that sends the matching data is remembered by the Router, so that when the requested data
returns through the Router, the data is pulled back to the proper computer by way of IP address and port mapping
rules.
Port Triggering
Application. Enter the application name of the trigger.
Triggered Range
For each application, list the triggered port number range. Check with the Internet application documentation for
the port number(s) needed.
Start Port. Enter the starting port number of the Triggered Range.
End Port. Enter the ending port number of the Triggered Range.
Forwarded Range
For each application, list the forwarded port number range. Check with the Internet application documentation for
the port number(s) needed.
Start Port. Enter the starting port number of the Forwarded Range.
End Port. Enter the ending port number of the Forwarded Range.

The Applications and Gaming Tab - DMZ
Wireless-G Broadband Router with SpeedBooster
The Applications and Gaming Tab - DMZ
The DMZ feature allows one network user to be exposed to the Internet for use of a special-purpose service such
as Internet gaming or videoconferencing. DMZ hosting forwards all the ports at the same time to one PC. The Port
Range Forward feature is more secure because it only opens the ports you want to have opened, while DMZ
hosting opens all the ports of one computer, exposing the computer to the Internet.
Any PC whose port is being forwarded must have its DHCP client function disabled and should have a new static
IP address assigned to it because its IP address may change when using the DHCP function.
To expose one PC, select Enable. Then, enter the computer's IP address in the DMZ Host IP Address field.

QoS
Quality of Service (QoS) ensures better service to high-priority types of network traffic, which may involve
demanding, real-time applications, such as videoconferencing.
There are three types of QoS available, Device Priority, Application Priority, and Ethernet Port Priority.
Enabled/Disabled. To limit outgoing bandwidth for the QoS policies in use, select Enable. Otherwise, select Disable.
Upstream Bandwidth. Select the bandwidth to be used from the drop-down menu.This setting allows you to
limit the outgoing bandwidth for the QoS policies in use, so you can control how much bandwidth a particular
application is allowed to use.
Device Priority
Enter the name of your network device in the Device name field, enter its MAC Address, then select its priority
from the drop-down menu.
Ethernet Port Priority
Ethernet Port Priority QoS allows you to prioritize performance for four of the Router’s ports, LAN Ports 1-4. For
each of these ports, select High or Low for Priority. For Flow Control, if you want the Router to control the
transmission of data between network devices, select Enable. To disable this feature, select Disable. The

QoS
Wireless-G Broadband Router with SpeedBooster
Router’s other four ports will be automatically assigned low priority. Incoming Rate Limit limits the incoming
bandwidth. To use this feature, select 8M, 4M, 2M, 1M, 512K, 256K, or 128K (M stands for Mbps, while K stands for kbps). If
you do not want to use this feature, keep the default, Disable.
Ethernet Port Priority QoS does not require support from your ISP because the prioritized ports are LAN ports
going out to your network.
Application Port Priority
Application Port Priority QoS manages information as it is transmitted and received. Depending on the settings of
the QoS screen, this feature will assign information a high or low priority for the five preset applications and three
additional applications that you specify. For each application, select High or Low for Priority. For Specific Port#, you
can add three additional applications by entering their respective port numbers in the Specific Port# fields.
FTP (File Transfer Protocol). A protocol used to transfer files over a TCP/IP network (Internet, UNIX, etc.). For
example, after developing the HTML pages for a website on a local machine, they are typically uploaded to the
web server using FTP.
HTTP (HyperText Transport Protocol). The communications protocol used to connect to servers on the World
Wide Web. Its primary function is to establish a connection with a web server and transmit HTML pages to the
client web browser.
Telnet. A terminal emulation protocol commonly used on Internet and TCP/IP-based networks. It allows a user at
a terminal or computer to log onto a remote device and run a program.
SMTP (Simple Mail Transfer Protocol). The standard e-mail protocol on the Internet. It is a TCP/IP protocol
that defines the message format and the message transfer agent (MTA), which stores and forwards the mail.
POP3 (Post Office Protocol 3). A standard mail server commonly used on the Internet. It provides a message
store that holds incoming e-mail until users log on and download it. POP3 is a simple system with little selectivity.
All pending messages and attachments are downloaded at the same time. POP3 uses the SMTP messaging
protocol.
Application Name. You can add three additional applications by entering their names in the Application Name
fields.

The Administration Tab - Management
This section of the Administration tab allows the network’s administrator to manage specific Router functions for
access and security.
Local Router Access. You can change the Router’s password from here. Enter a new Router password and then
type it again in the Re-enter to confirm field to confirm.
Web Access. HTTP (HyperText Transport Protocol) - The communications protocol used to connect to servers on
the World Wide Web. HTTPS - Uses SSL (Secured Socket Layer) to encrypt data transmitted for higher security.
Select HTTP or HTTPS. Wireless Access Web - If you are using your Wireless Router in a public domain where you
are giving wireless access to your guests, you can disable wireless access to the router’s web-based utility. You
will only be able to access the web-based utility via a wired connection if you disable the setting. Select Enable
to enable wireless access to the Router’s web-based utility or Disable to disable wireless access to the utility.
Remote Router Access. To access the Router remotely, from outside the network, verify that Enable is selected.
Then, enter the port number that will be open to outside access. You will need to enter the Router’s password
when accessing the Router this way, as usual.
UPnP. When using UPnP features, select Enable. Because allowing this may present a risk to security, this
feature is disabled by default.

The Administration Tab - Log
The Router can keep logs of all traffic for your Internet connection. To disable the Log function, keep the default
setting, Disable. To monitor traffic between the network and the Internet, select Enable. When you wish to view
the logs, click Incoming Log or Outgoing Log, depending on which you wish to view.
