manually.

Select this and manually enter the server's IP address.

number(s) and protocol will be displayed in the port forwarding summary table.
Otherwise, select User define to manually enter the port number(s) and select the IP
protocol.

UDP, or TCP_UDP.

configured automatically.

forwarding summary table.
