How to beat the Google DNS query flood?

Question

Google

Hi all!
Faced with the blocking of my network by Google.
I found a large number of requests and connections from my external IP to 8.8.8.8 and to 8.8.4.4 (they are registered in MikroTik as DNS servers
)

Answer 1

Close recursive DNS from outside your network. Something like this:

Answer 2

1. Close tcp and udp port 53 for access from the provider's interface (in input)
2. Be sure to specify out-interface in the masquerading rule.
I will not paint, there is nothing complicated here
