Wireless-G ADSL Home Gateway
Applications & Gaming > Port Range
Triggering
The
Port Range Triggering
screen allows the Gateway to
watch outgoing data for specific port numbers. The IP
address of the computer that sends the matching data is
remembered by the Gateway, so that when the requested
data returns through the Gateway, the data is pulled back
to the proper computer by way of IP address and port
mapping rules.
Applications and Gaming > Port Range Triggering
Port Range Triggering
To trigger a port range, enter the information on each line
for the criteria required.
Application Name
Enter the application name of the
trigger.
Triggered Range Start Port and End Port
For each
application, enter the starting and ending port numbers of
the triggered port number range. Check with the Internet
application
documentation
for
the
port
number(s)
needed.
Forwarded Range Start Port and End Port
For each
application, enter the starting and ending port numbers
of the forwarded port number range. Check with the
Internet application documentation for the port number(s)
needed.

Applications and Gaming > DMZ
The DMZ feature allows one network computer 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 computer. The Port Range Forwarding 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.
Applications and Gaming > DMZ
DMZ
Any computer 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.
DMZ Hosting
To disable DMZ hosting, keep the default,
Disable
. To expose one computer, select
Enable
. Then
configure the following setting:
DMZ Host IP Address
Enter the IP address of the
computer.

Applications and Gaming > QoS
Quality of Service (QoS) ensures better service to high-
priority network traffic, which may involve demanding,
real-time applications, such as videoconferencing.

QoS (Quality of Service)
QoS
To use QoS, select
Enable
. Otherwise, keep the
default,
Disable
.
Application-based QoS
Application-based QoS manages information as it is
transmitted and received. Depending on the settings of
the
QoS
screen, this feature will assign information a high,
medium, or low priority for the five preset applications
and three additional applications that you specify.
The five preset applications are the following:
FTP (File Transfer Protocol)
A protocol used to transfer files over a TCP/IP network
(Internet, UNIX, etc.). For example, after HTML pages
are developed 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.
Specific Port#
You can add three more applications by
entering their respective port numbers in these fields.
High priority/Medium priority/Low priority
For each
application, select
High priority
(traffic on this queue
shares 70% of the total bandwidth),
Medium priority
(traffic on this queue shares 15% of the total bandwidth),
or
Low priority
(traffic on this queue shares 10% of the
total bandwidth).
