The Applications and Gaming Tab - Port Triggering

Wireless-G Broadband Router with SRX200

The Applications and Gaming Tab - Port Triggering

Port Triggering is used for special applications that can request a port to be opened on demand. For this feature,

the Gateway will watch outgoing data for specific port numbers. The Gateway will remember the IP address of the

computer that sends a transmission requesting data, so that when the requested data returns through the

Gateway, the data is pulled back to the proper computer by way of IP address and port mapping rules.

Port Triggering

Application

. In this field, enter the name you wish to give the application.

Triggered Range and Forwarded Range

Start Port and End Port

. Enter the starting and ending port numbers of the Triggered Range and Forwarded

Range.

Enable

. Click the

Enable

checkbox to enable port triggering for the relevant application.

The Applications and Gaming Tab - DMZ

The DMZ feature allows one network user to be exposed to the Internet for use of a special-purpose service such

as Internet gaming or videoconferencing. DMZ hosting forwards all the ports at the same time to one PC. The Port

Range Forward feature 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 expose one PC, select

Enable

. Then, enter the computer's IP address in the

DMZ Host IP Address

field.

Chapter 5: Configuring the Wireless-G Broadband Router

The Applications and Gaming Tab - QoS

Wireless-G Broadband Router with SRX200

The Applications and 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 videoconferencing.

QoS (Quality of Service)

Wireless

ACK Mode

. This setting prioritizes QoS for users who also have ACK Mode enabled. Users with Immediate ACK

(the default setting) will experience reliable connectivity for normal network use. Burst ACK is faster but less

reliable and may also affect long-range wireless performance. The No ACK setting disables the ACK feature.

Clients utilizing ACK must have their wireless adapter on the same setting as the Router. This is normally used in

a multicast broadcast like video. Do not use this unless you are an advanced user.

802.11e/QoS

. QoS will be enabled by default to provide the best performance for your wireless connection.

Select

Disable

to improve performance for a mixed wireless network.

Internet Access Priority

In this section, you can set priority based on Application, Port Range, or MAC Address. There are four priories you

can set: High, Medium, Normal, or Low.

Enable/Disable

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

Enable

. Otherwise, select

Disable

.

Set Internet Bandwidth

. This setting allows you to limit the outgoing bandwidth for the QoS policies in use, so

you can control how much bandwidth a particular application is allowed to use. Enter the bandwidth in the field.

Application

. With this option you can select

None

,

Add a New Application

,

Voice Device,

Online Game

, or

select from the list of applications you want to set. To create a new entry, select

Add a New Application

, and

refer to the

Add a New Application

section.

Priority

. Select the bandwidth priority for the application you selected. Select

High

,

Medium

,

Normal

, or

Low

for the bandwidth you need for that application. Don’t set all applications to High, because this will defeat the

purpose of allocating the available bandwidth. If you want to select below normal bandwidth, select

Low

.

Depending on the application, a few attempts may be needed to set the appropriate bandwidth priority. Once you

have made your selection, click

Add

to add to the Summary list.

Add a New Application

Enter a Name

Enter any name to indicate the name of the entry.

Category

Select from

Port Range

or

MAC Address

for the Router to use to set the bandwidth priority.

Port Range

If you selected Port Range, then this category will be available. It allows you to enter the port

range that the application will be using. For example, if you want to allocate bandwidth for FTP,

you can enter 21-21. If you need services for an application that uses from 1000 to 1250, you

enter 1000-1250 as your settings. You can have up to three ranges to define for this bandwidth

allocation. Port numbers can range from 1 to 65535. Check your application's documentation

for details on the service ports used.

MAC Address

If you selected MAC Address, then this category will be available. Enter the 12 hexadecimal

digit MAC Address to represent the device you want to set as a bandwidth priority.

This is a

unique identifier for your network device. When the Router identifies the device entered, the

Router will allocate the priority set for that entry. Check the device’s documentation to obtain

the MAC Address.

Priority

Select the bandwidth priority for the application you selected. Select

High

,

Medium

,

Normal

,

or

Low

for the bandwidth, but don’t set all applications to High. Once you have made your

selection, click

Add

to add to the Summary list.

Voice Device

Enter the name of your network device in the

Enter a Name

field, enter its MAC Address, select its priority

from the drop-down menu, and click

Add

.

Online Game

Selecting Online Game will display the

Select a Game

drop-down menu, which will list a few common pre-

configured games. Select the game from the list, and then select its priority.

Summary

Priority

This displays the bandwidth allocation priority of High, Medium, Normal, or Low, that you set

for the application.

Name

This displays the application name or the entries you entered to be allocated.

Information

This displays the Port Range or MAC Address entered when you added a new application. If a

pre-configured application was selected, there will be no valid entry shown in this section.

The Administration Tab - Management

This section of the Administration tab allows the network’s administrator to manage specific Router functions for

access and security.

Router Password

Local Router Access

Router Password and Re-enter to confirm

. You can change the Router’s password from here. Enter a new

Router password and then type it again in the

field to confirm.

Remote Router Access

Remote Management and Management Port

. To access the Router remotely, from outside the network, verify

that

Enable

is selected. Then, enter the port number that will be open to outside access. You will need to enter

the Router’s password when accessing the Router this way, as usual.

UPnP

UPnP

. UPnP allows Windows XP and Windows Me to automatically configure the Router for various Internet

applications, such as gaming and videoconferencing. To enable UPnP, check the

Enable

radio box. Because

allowing this may present a risk to security, this feature is disabled by default.

Multicast

Multicast Pass Through

. Multicasting allows for multiple transmissions to specific recipients at the same time.

If multicasting is permitted, then the Router will allow IP multicast packets to be forwarded to the appropriate

computers. Select

Enable

to allow multicasting, or
