Chapter 5: Configuring the Router

The Applications & Gaming Tab - Port Trigger

Broadband Router with 2 Phone Ports

The Applications & Gaming Tab - Port Trigger

The

Port Trigger

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.

Port Trigger

Application

. Enter the application name of the trigger.

Triggered Range

Protocol

. Select the protocol

TCP

or

UDP

.

For each application, list the triggered port number range. Check with the Internet application documentation for

the port number(s) needed.

Start Port

. Enter the starting port number of the Triggered Range.

End Port

. Enter the ending port number of the Triggered Range.

Forwarded Range

Protocol

. Select the protocol

TCP

or

UDP

.

For each application, list the forwarded port number range. Check with the Internet application documentation for

the port number(s) needed.

Start Port

. Enter the starting port number of the Forwarded Range.

End Port

. Enter the ending port number of the Forwarded Range.

Enable

. Check the

Enable

box to enable the application you have defined. Port Triggering for a specific

application will not function if its Enable box is left unchecked. This is disabled (unchecked) by default.

Chapter 5: Configuring the Router

The Applications & Gaming Tab - UPnP Forward

Broadband Router with 2 Phone Ports

The Applications & Gaming Tab - UPnP Forward

The

UPnP Forward

screen displays preset application settings as well as options to customize port services for

other applications.

UPnP Forward

Application

. Ten applications are preset. For custom applications, enter the name of your application in one of

the available fields.

The preset applications are among the most widely used Internet applications. They include the following:

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.

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.

DNS

(Domain Name System). The way that Internet domain names are located and translated into IP addresses. A

domain name is a meaningful and easy-to-remember “handle” for an Internet address.

TFTP

(Trivial File Transfer Protocol). A version of the TCP/IP FTP protocol that has no directory or password

capability.

Finger

. A UNIX command widely used on the Internet to find out information about a particular user, such as a

telephone number, whether the user is currently logged on, and the last time the user was logged on. The person

being “fingered” must have placed his or her profile on the system in order for the information to be available.

Fingering requires entering the full user@domain address.

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.

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.

NNTP

(Network News Transfer Protocol). The protocol used to connect to Usenet groups on the Internet. Usenet

newsreaders support the NNTP protocol.

SNMP

(Simple Network Management Protocol). A widely used network monitoring and control protocol. Data is

passed from SNMP agents, which are hardware and/or software processes reporting activity in each network

device (hub, router, bridge, etc.) to the workstation console used to oversee the network. The agents return

information contained in a MIB (Management Information Base), which is a data structure that defines what is

obtainable from the device and what can be controlled (turned off, on, etc.).

Ext. Port

. Enter the number of the external port used by the server in the

Ext. Port

column. Check with the

Internet application documentation for more information.

TCP or UDP

. Select the protocol

UDP

or

TCP

for each application. You cannot select both protocols.

Int. Port

. Enter the number of the internal port used by the server in the

Int. Port

column. Check with the Internet

application software documentation for more information.

IP Address

. Enter the IP address of the server that you want the Internet users to be able to access. To find the IP

address, go to “Appendix C: Finding the MAC Address and IP Address for Your Ethernet Adapter.”

Enable

. Check the

Enable

box to enable the application you have defined. UPnP Forwarding for a specific

application will not function if its Enable box is left unchecked. This is disabled (unchecked) by default.

Chapter 5: Configuring the Router

The Applications & Gaming Tab - DMZ

Broadband Router with 2 Phone Ports

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. 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.

DMZ

DMZ

. To use this feature, select

Enable

. To disable DMZ hosting, select

Disable

.

DMZ Host IP Address

. To expose one PC, enter the computer’s IP address. To get the IP address of a computer,

refer to “Appendix C: Finding the MAC Address and IP Address for Your Ethernet Adapter.” Deactivate DMZ by

entering

0

in the field.
