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 elds.

The Destination Port Map eld species 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 eld) will be the same as the rst 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 elds (Port Start, Port End and Port Map) will have the

same port number.
