The Applications & Gaming Tab - Port Range Forwarding

When you click the Applications & Gaming tab, you will see the

Port Range Forwarding

screen. Port Range

Forwarding sets up public services on your network, such as web servers, ftp servers, e-mail servers, or other

specialized Internet applications. (Specialized Internet applications are any applications that use Internet

access to perform functions such as videoconferencing or online gaming. Some Internet applications may not

require any forwarding.) When users send this type of request to your network via the Internet, the Router will

forward those requests to the appropriate PC.

Before using forwarding, you should assign a static IP address to the designated PC.

If you need to forward all ports to one PC, click the

DMZ

tab.

Port Range Forwarding

Port Range

To add a server using Port Range Forwarding, complete the following fields:

Application

. Enter the name of the application.

Start and End

. Enter the number or range of external port(s) used by the server or Internet application. Check

with the Internet application software documentation for more information.

Protocol

. Select the protocol

TCP

or

UDP

, or select

Both

.

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.”

ip

(internet protocol): a protocol used to

send data over a network.

ip address

: the address used to identify a

computer or device on a network.

tcp

: a network protocol for transmitting

data that requires acknowledgement from

the recipient of data sent.

udp

: a network protocol for transmitting

data that does not require

acknowledgement from the recipient of

the data that is sent.

The Applications & Gaming Tab - Port Triggering

Enable

. Check the

Enable

box to enable the services you have defined. Port Range Forwarding will not function

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

When you have finished making changes to this screen, click the

The Applications & Gaming Tab - Port Triggering

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.

Port Triggering

Application

. Enter the application name of the trigger.

Triggered Range

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.

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

. To use this feature, select

Enabled

. To disable DMZ hosting, select

Disabled

.

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 a

0

in the field.

When you have finished making changes to this screen, click the

Chapter 5: Configuring the Router

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.

Use this screen to configure IP QoS for connections, view the rules you have set up, and manage your rules.

IP QoS

Choose a connection

. Choose the appropriate connection from the drop-down menu.

Low priority weight

. Select the weight of the low priority queue, which is available in increments of 10%. The

sum of the low and medium priority weights should equal 100%.

Medium priority weight

. Select the weight of the medium priority queue, which is available in increments of

10%. The sum of the low and medium priority weights should equal 100%.

Enable IP QoS

. Click this checkbox to enable IP QoS for the selected connection.

Trusted Mode

. The Router has two modes for management of queue traffic. Click the

Trusted Mode

checkbox if

you want the Router to apply all of the IP QoS rules first, regardless of the TOS bit settings. After the rules have

been applied, then the TOS bit settings will be applied. If Trusted Mode is not used, then the Router will use the

un-trusted mode. The default rule will be applied if the there is no match between the un-trusted mode and the

rules of the Trusted Mode. (The default rule will assign a low queuing priority.)

The following table will list the rules you have configured. You can also add new rules and delete existing rules.

Each rule uses the criteria you specified to identify specific types of application traffic, which should be assigned

to one of the Router’s three priority queues: High, Medium, or Low.

Figure 5-19: Applications & Gaming Tab -

QoS

NOTE:

If IP QoS is enabled

and you have no defined

rules, then a default rule will

be implemented. All traffic

will be transmitted in the Low

priority queue.
