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 f
uture 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.
