Here is an example for IP Access Setting. Enter the range of 51~80 in the “Filter Group”
column and 20~80 in the “Block Port Range” column, then click the “Apply” button. As a
result, the user’s computers which have IP Addresses in the range of 192.168.1.51 to
192.168.1.80 will not be able to use the applications which use port numbers from 20 to 80,
