Advanced Configuration

Applications and Gaming > DMZ

The DMZ feature allows one network computer 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 Forwarding 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.

DMZ

Any computer 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 Hosting To disable DMZ hosting, keep the default, Disable. To expose one PC, select Enable. Then configure the following setting:

DMZ Host IP Address Enter the IP address of the computer.

Click Save Settings to apply your changes, or click Cancel Changes to cancel your changes.

Applications and Gaming > 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.

Applications and Gaming > QoS

Wireless

The Gateway features Wi-Fi Multimedia (WMM™) Support. The No Acknowledgement feature is available only when the WMM Support feature is enabled.

WMM Support Wi-Fi Multimedia is a QoS feature defined by WiFi Alliance before IEEE 802.11e was finalized. Now it is part of IEEE 802.11e. When it is enabled, it provides four priority queues for different types of traffic. It automatically maps the incoming packets to the appropriate queues based on QoS settings (in IP or layer 2 header). WMM provides the capability to prioritize traffic in your environment. If you have other devices on your network that support WMM, keep the default, Enabled. Otherwise, select Disabled.

No ACK If you want to disable the Gateway’s Acknowledgement feature, so the Gateway will not re- send data if an error occurs, then keep the default, Enabled. Otherwise, select Disabled.

Internet Access Priority

In this section, you can set the bandwidth priority for a variety of applications and devices. There are four levels priority: High, Medium, Normal, or Low. When you set priority, do not 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.

Enabled/Disabled To use the QoS policies you have set, select Enabled. Otherwise, select Disabled.
