Check this box to enable IP Address Filtering.
Filter
Method
The filter can be set in either “Allow” mode or “Block” mode.
1. “Allow” mode will refuse access to all IP addresses except the
ones listed below.
2. “Block” mode will accept all incoming access except the IP
addresses listed below.
Make sure you include the Netmask in your consideration.
IP Address
The IP address you wish to allow or block. Please note that the
actual range is modified by the Netmask.
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. .
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.
Apply
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.
