Download Block Internet Access By Mac Address Pictures. I want to block internet some pcs by mac address,so when i created an policy device identity with authentication rules action=deny,all pcs couldn't access internet. As you can see, blocking by mac address is a far more effective solution.

If i assume, i know the mac address of pi, is it possible to kick off any device that does not match that mac address?

As you mention the simple way is to just leave the gateway blank. How can i block someone's internet access using the mac address, i only want to block internet access and let all other traffic pass through. Any user that can change that can change the ip from the router access settings with your router. Mac addresses are a lan thing, not an internet thing.
