*1. If you select any, packets from any IP addresses will be allowed.
*2. The allowed IP address is calculated by the logical AND of the IP address
and the Mask
. If you want to
allow more than one IP address, mask a part of the IP address by setting the Mask. In this case, set 0 to
the bits to be masked in the IP address and Mask.
The following is an example of how to calculate the allowed IP addresses.
Example 1. Allowing IP address 192.168.250.1
If you want to allow one IP address, set 255.255.255.255 to the mask.
Setting Decimal notation Binary notation
IP address 192.168.250.1 11000000.10101000.11111010.00000001
Mask 255.255.255.255 11111111.11111111.11111111.11111111
Example 2. Allowing IP address 192.168.250.***
Set 255.255.255.0 to the mask to mask the lower 8 bits of the IP address.
Setting Decimal notation Binary notation
IP address 192.168.250.0 11000000.10101000.11111010.00000000
Mask 255.255.255.0 11111111.11111111.11111111.00000000
Example 3. Allowing IP address 192.168.250.1 to 192.168.250.31
Set 255.255.255.224 to the mask to mask the lower 5 bits if the IP address.
Setting Decimal notation Binary notation
IP address 192.168.250.0 11000000.10101000.11111010.00000000
Mask 255.255.255.224 11111111.11111111.11111111.11100000
*3. Set 0 to the bits to be masked in Mask. Multiple bits can be masked, but only bits from the least signifi-
cant can be masked. It is not possible to mask the higher bits, such as 0.255.255.255, or the middle bits,
such as 255.0.255.255.
The following are examples of setting a mask.
