Port Triggering

screen allows the Router to watch outgoing data for specific port numbers. The IP address

of the computer that sends the matching data is remembered by the Router, so that when the requested data

returns through the Router, the data is pulled back to the proper computer by way of IP address and port

mapping rules.

The Applications & Gaming Tab - DMZ

The Applications & Gaming Tab - DMZ

The

DMZ

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

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

Port Range Forwarding 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.
