The Port Triggering Tab

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 Range Triggering

•

Application. Enter the name you wish to give each application.

•

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

•

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

•

Enabled. Click the

Enabled

checkbox to enable port triggering for the chosen application.

The

screen allows one local user to be exposed to the Internet for use of a special-purpose service such as

Internet gaming and videoconferencing through DMZ Hosting. DMZ hosting forwards all the ports for one

computer at the same time, which differs from Port Range Forwarding, which can only forward a maximum of

10 ranges of ports.

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.

•

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 Gateway. This is

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

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.

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

Port Range

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

range(s) 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. Port numbers can range from 1 to 65535. Check your

application's documentation for details on the service ports used.

You can define up to three ranges for this bandwidth allocation. For each port range, designate

the protocol type(s):

TCP

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
