The fields in the above window are described as follows:
??
Protocol – [UDP] or [TCP]. This field designates the type of
packets that will be acted on.
??
Start Port – Some applications can only send data over a certain
range of port numbers. Thus, all port numbers in the specified range
must be exempt from the NAPT port translation process. This field
defines the beginning range of the port numbers to be exempted
from the NAPT port translation process.
??
End Port – This field defines the last port number in the range of
numbers excluded from the NAPT process (see Start Port above).
??
Connection Type – [Outgoing Control] or [Incoming Data]. The
user must initially run the special application and send a request to
the application server on the Internet. This outgoing request to join
a Diablo server, for example, is used to trigger the exemption
process for the incoming data.
