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 B: Finding the MAC Address and IP Address for Your Ethernet Adapter.”

Enabled

. Check the

Enabled

box to enable the service you have defined. UPnP Forwarding will not function if

the Enabled button is left unchecked. This is disabled (unchecked) by default.

The Applications & Gaming Tab - DMZ

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.

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 B: Finding the MAC Address and IP Address for Your Ethernet Adapter.” Deactivate DMZ by

entering a

0

in the field.

The Applications & Gaming Tab - QoS

The Applications & Gaming 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.

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.

Enable/Disable

. To use application-based QoS, select

Enable

. Otherwise, keep the default,

Disable

.

High priority/Low priority

. For each application, select

High priority

or

Low priority

.

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 additional applications by entering their respective port numbers in the

Specific Port#

fields.

Port-based QoS

Port-based QoS allows you to prioritize performance for three of the Router’s ports, LAN Ports 1-3. Port-based

QoS does not require support from your ISP because the prioritized ports are LAN ports going out to your

network.

Enable/Disable

. To use port-based QoS, select

Enable

. Otherwise, keep the default,

Disable

.

For each port, specify the Priority, Flow Control setting, and Ingress Rate Limit.

Priority

. Select the port’s priority level,

High

or

Low

.

Flow Control

. If you want the Router to control the transmission of data between network devices, select

Enable

. To disable this feature, select

Disable

.

Ingress Rate Limit

. This setting limits the incoming bandwidth. To use this feature, select

8M

,

4M

,

2M

,

1M

,

512K

,

256K

, or

128K

(M stands for Mbps, while K stands for kbps). If you do not want to use this feature, keep

the default,

Disable

.

Voice QoS

This setting allows you to limit the outgoing bandwidth for the application- or port-based QoS policies in use, so

you can control how much bandwidth a particular application is allowed to use.

Enable/Disable

. To limit outgoing bandwidth for the QoS policies in use, select

Enable

. Otherwise, select

Disable

.

QoS Upstream Rate

. If you want the Router to automatically detect the QoS upstream rate, keep the default,

Auto Detect

. The rate will be automatically displayed. If you want to manually set the maximum QoS upstream

rate, select

Manual

. Then enter the maximum speed in kbps; the default is

256

kbps.
