Use the

Single Port Forwarding

screen when you want to open a specific port so users on the Internet can see the

servers behind the Gateway (such servers may include FTP or e-mail servers). When users send this type of

request to your network via the Internet, the Gateway will forward those requests to the appropriate computer.

Any computer whose port is being forwarded should 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.

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.
