Classification Engine: The end of the range is excluded, which is not intuitive

The port values (src and dst) allow values between 0 and 65535.
However the input also accepts 65536, which results in a 500 Internal Server Error.

Please ensure that 0-65535 is actually creating the ranges properly and not excluding the 65535 and therefore only creating a range of 0-65534 as this is not very intuiitve.

In any case, ensure that 65536 is not a valid option.
