drop Web CFS DNS reply pkt
I've found some packet dropped by the firewall (TZ570, 7.0.1-5065) originating from google DNS 18.104.22.168 to our WAN IP firewall due to the cause reported in the object:
DROPPED, Drop Code: 712(Packet dropped - drop Web CFS DNS reply pkt), Module Id: 25(network), (Ref.Id: _723_iboemfXfcDgt) 1:1)
Google DNS is set as the first DNS Server IP in our WAN config. CFS is currently enabled and enforced
Any clue about a possibile cause?
