bers. Some applications specify a range of ports in which case you will need to know
both the starting and ending port numbers in the range, which are mapped by the
start port and end port fields.
The Destination Port Map field specifies the internal port that the data will be
directed to on the LAN Client. When dealing with port ranges, the Internal Port (des-
ignated by the Port Map field) will be the same as the first port in the range. When
you simply want to forward a single port from outside (i.e. WAN side) to inside (i.e.
LAN side), then all three fields (Port Start, Port End and Port Map) will have the
same port number.
