Forwarding screen. You can decide whether you want to use the default server
or specify a server manually.
Select this to use the default server.
Select this and manually enter the server's IP address.

service port number(s) and protocol will be displayed in the Port Forwarding
Summary section.
Otherwise, select User define to manually enter the port number(s) and select
the IP protocol.

TCP, UDP, or TCP&UDP.

will be configured automatically.

the Port Forwarding Summary section.
