Forward to Internal Port
The IP port number to which packets containing the specified port number are to be
redirected. When set to 0, no port remapping occurs and the router uses the original port
number. The NAT mode parameter of the appropriate interface must be set to NAPT rather
than NAT or OFF for this parameter to take effect.
