Wireless-G ADSL Gateway with SpeedBooster
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 PC, 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 types of 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 60% of the total bandwidth), Medium priority
(traffic on this queue shares 18% of the total bandwidth),
or Low priority (traffic on this queue shares 1% of the
total bandwidth).
