1.
IP Address filter enable:
Check this box to enable IP Address Filtering.
2.
FILTER:
The filter can be set in either “Allow” mode or “Deny” mode.
“Allow” mode will refuse access to all IP addresses except the ones listed below.
“Block” mode will accept all incoming access except the IP addresses listed
below.
Make sure you include the Netmask in your consideration.
3.
IP Address:
The IP address you wish to allow or block. Please note that the
actual range is modified by the Netmask.
4.
Netmask:
Using Netmask allows you to set filtering for a whole range of IP
address at once, without the need to enter all of them individually. If you are not
sure about the function of netmask, then you should use 255.255.255.255, and it
will affect only a single IP address per line of entry, or use 255.255.255.0 to use
the same setting for all IP addresses starting with the same three numbers.
5.
Enable:
For each entry, you must check this box for it to be effective. For an
entry that you no longer need but does not wish to delete, you can uncheck it,
and the system will remember it for future use. If a new entry that has never been
used before does not have Enable checked, then it will not be stored in memory.
6.
Apply Button:
Click this to use the current displayed info to do IP Address
filtering. If you setup correctly, it will change into a grayed out “Success” in a
few seconds.
