The Application section of the Port Open settings panel contains a number, a
Name input box, and Save and Cancel buttons.
The number is the number of the application for which Port Open settings
currently appear (see “Go to,” above).
The Name box helps you identify the application that the displayed settings
are for. To enter a name, click in this box and type any text up to 32 characters
long. Spaces and punctuation can be used. The name serves only as a reminder;
it does not affect operation in any way.
The Save and Cancel buttons work slightly differently from those in other
settings panels. They affect only the Enable setting and the contents of the
Name input box. Click Save to store these settings (but not those in the Define
Port Open List section of the panel) in the Wireless Gateway's non-volatile
memory; click Cancel to restore them to the values last saved to or retrieved
from the Wireless Gateway.
Define Port Open List
For the Port Open function to work, the Wireless Gateway must “know”
which port or ports an application uses for input from the WAN (and, in some
cases, output from the user's machine to the WAN). The Define Port Open List
section of the Port Open settings panel lets you list the port or ports an
application uses for input and output.
An application might use a single port for all input and output, or a different
port in each direction, or multiple ports (contiguous or non-contiguous) in one
direction or both. The Define Open Port List section of the Port Open settings
panel lets you input settings for all patterns of port use, from the simplest to
the most complex. The controls in this section are explained below.
The I/O control can be set to In or Out. This setting has no immediate effect.
Its effect comes when you click Add to store Start Port and End Port numbers
in the Wireless Gateway's non-volatile memory. If the I/O control is set to In,
the specified port or ports will be treated by the Wireless Gateway as input
ports; if it is set to Out, they will be treated as output ports.
The Start Port and End Port boxes are for specifying a port or a range of
ports. To specify a single port, click and type the same number into both boxes;
