Port Triggering

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.

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

Start Port and End Port. Enter the starting and ending Triggered Range numbers and the Incoming Forwarded Range numbers of the port you wish to forward.

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 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.

DMZ Hosting. This feature allows one local user to be exposed to the Internet for use of a special-purpose service such as Internet gaming and videoconferencing. To use this feature, select Enabled. To disable DMZ , select Disabled.

DMZ Host IP Address. To expose one computer, enter the computer’s IP address. To get the IP address of a computer, refer to “Appendix D: Finding the MAC Address and IP Address for Your Ethernet Adapter.”
