The DMZ Tab

The

DMZ

screen allows one local user to be exposed to the Internet for use of a special-purpose service such as

Internet gaming and videoconferencing through DMZ Hosting. DMZ hosting forwards all the ports for one

computer at the same time, which differs from Port Range Forwarding, which can only forward a maximum of 10

ranges of ports.

The QoS Tab

QoS

Quality of Service (QoS) ensures better service to high-priority types of network traffic, which may involve

demanding, real-time applications, such as Internet phone calls or videoconferencing.

Enabled/Disabled

. 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 or low priority for the five preset applications and three

additional applications that you specify.

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).

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.

Specific Port#

. You can add three more applications by entering their respective port numbers in these fields.
