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.

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.

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 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).
