Hello, I need to block google DNS to get getflix work (It says proxy error) in some websites.
The problem is that Cisco DPC3825 doesn't have the "Advanced routing" option to block public DNS static route.
Example I need to block this: Network Address: 8.8.8.8
Subnet Mask: 255.255.255.255
and this Network Address: 8.8.4.4
Subnet Mask: 255.255.255.255
Without this tab I don't know how to do it and I'm too noob in these kind of things.
Is there any easy way to block those DNS to get Getflix work?
