Applications & Gaming > Port Range Triggering The Port Range Triggering screen allows the Router to watch outgoing data for specific port numbers.

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. Applications and Gaming > DMZ DMZ Any computer whose port is being forwarded should have its DHCP client function disabled and have a new static IP address assigned to it because its IP address may change when using the DHCP function. Enabled/Disabled To disable DMZ hosting, select Disabled. To expose one PC, select Enabled. Then configure the following settings: Source IP Address If you want any IP address to be the source, select Any IP Address. If you want to specify an IP address or range of IP addresses as the designated source, select and complete the IP address range fields. Destination If you want to specify the DMZ host by IP address, select IP Address and enter the IP address in the field provided. If you want to specify the DMZ host by MAC address, select MAC Address and enter the MAC address in the field provided.
