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.

The Applications & Gaming Tab - DMZ
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. DMZ hosting forwards all the ports at the same time to one PC. The
Port Range Forwarding 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.

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
