Port Mapping
Some applications, such as Internet gaming, videoconferencing, Internet telephony
and others, require multiple connections. These applications cannot work with
one-to-one address/port translation. If you need to run applications that require
multiple connections, use port mapping to specify the additional public ports to be
opened for each application.
