118 / 122
Dst Mask
Is the destination address mask. When configured as 255.255.255.255, it
means the specific host. When set as 255.255.255.0, it means that a network
segment is filtered.
After setting, click [Add] and a new item will be added in the firewall input rule, as shown in the figure below:

Then select and click the button [Apply].
In this way, when the device is running: ping 192.168.1.118, the packet cannot be sent to 192.168.1.118
because the output rule is forbidden. However, the other IP of the ping 192.168.1.0 network segment can still
receive the response packet from the destination host normally.
