Since we updated HiveOS to V10.3 there are some strange DNS-Queries log entries in the Firewall.
We do not use Cloud-Services, we are working with APs on hivemanager Classic.
The APs do not have connections to the Internet.
The Problem: from V10.3 on there are strange DNS-Requests to www.google.com from the AP directly, not to the local DNS, but to a DNS-Server which we use in our Guest-WLAN => open to the internet, but it’s not accessible from the AP management-VLAN (tagged Port). The AP uses a DNS-Server which is not configured on them; they get the local DNS-Server, which is seen by “show dns”. But the request is send to the DNS-Server in the Guest-WLAN, which will be given via DHCP ONLY to Clients in a tagged VLAN (same Eth-Port like the AP).
I have found some things like “ping 126.96.36.199” and Client-Tracking via DNS/Google. But this way is not working and I have a firewall, which is actually blocking this traffic. But the Logs are full! See: there are up to 3 Requests from one AP, together we have about 250 APs Aerohive AP 130 running.
Can anybody help to stop these requests???
Hope, my words are not confusing…
