Yes thanks for the confirmation.
Actually, my setup is a dual wan (Failover) setup and i have put on the DNS Forwarders for ANY 4 IP address two of each ISP DNS servers.
I see these messages also when I make a DNS Lookup for an address from 3 IP of dns servers of them…so I guess only one DNS server of the Active Wan is responding. Is this normal?
DNS lookups works fine!
Do I have to put all DNS servers at DNS Forwarders?
