The Applications and Gaming Tab

Single Port Forwarding

The Single Port Forwarding screen provides options for customization of port services for common applications.

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.

Choose or enter the Application in the field. Then, enter the External and Internal Port numbers in the fields.

Select the type of protocol you wish to use for each application: TCP or UDP. Enter the IP Address in the field.

Click Enabled to enable UPnP Forwarding for the chosen application.

When finished making your changes on this tab, click the Save Settings button to save these changes, or click the Cancel Changes button to undo your changes.
