Wireless-G Router for Mobile Broadband

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.

Change these settings as described here, and click the Save Settings button to apply your changes or Cancel Changes to cancel your changes.

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.

There are three types of Wired QoS available, Device Priority, Application Priority, and Ethernet Port Priority. You can also configure Wireless QoS on this page.

Wired QoS

Enable/Disable. To limit outgoing bandwidth for the QoS policies in use, select Enable. Otherwise, select Disable.

Upstream Bandwidth. Select the bandwidth to be used from the drop-down menu. 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.

Device Priority

Device name, Priority, and MAC Address. For each device, enter the name of your network device in the Device name field. Then select its Priority and enter its MAC Address.
