How does it works?
When you check “protect my PC”, netCut will ensure both Gateway and your own PC has the right ARP mapping.
Netcut keep alive APR message will keep Gateway and your own PC aware of the correct mapping, the netcut will detect any spoofing packet, and response with correction action immediately.
