I'm a computer security student whom has recently been tasked with conducting an arp spoofing attack on a couple devices on a test network. The issue I'm facing is that none of the devices seem to be responding to any sort of arp spoofing. I can run nmap and scan through the network and see all the devices that are connected to the same AP as I am, so I know I can at least see the devices.
Note: The network is a PEAP network with mschapv2
So my question is: When conducting an arp-spoof attack on a network, can a router detect, and then throw away bogus arp-replys?
