Anti-Spoof Cache
The MAC-IP Anti-Spoof Cache lists all the devices presently listed as “authorized” to access
the network, and all devices marked as “blacklisted” (denied access) from the network. To add
a device to the list, click the Add button.
A window is now displayed that allows for manual entry of the IP and MAC addresses for the
device. Enter the information in the provided fields. You may also select to approve or blacklist
the routing device. Checking the router setting allows all traffic coming from behind this device.
Blacklisting the device will cause packets to be blocked from this device, irrespective of its IP
address. Once your entries have been made, click OK to return to the main panel.
