ADSL2+ Gateway with VoIP

The Applications & Gaming - Single Port Forwarding Tab

Single Port Forwarding

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.

PVC Connection Select. If the service requests you wish to configure will be coming in over a PVC other than

PVC 1, select the correct PVC from this list.

PortMap List. In this section you will customize the port service for your applications.

• Application. Enter the name of the application in the field provided.

• External Port and Internal Port. Enter the External and Internal Port numbers.

• Protocol. Select the protocol you wish to use for each application: TCP or UDP.

• IP Address. Enter the IP Address of the appropriate computer.

• Enabled. Click Enabled to enable 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.
