Dear community, I do have many error in my Bind's log file such as :
client 192.168.201.1#29404: error sending response: host unreachable It seems that I have an iptables issue as each time I shut iptables I don't have anymore this message showing up. I saw that my firewall is dropping packets from the DNS server itself towards the client, as the source port is SPT=53/UDP. I am using bind 9.6, it should use random port >1024 for the source port. (I didn't specify query-source parameter). Nevertheless dns resolution seems to be working find. Any idea ? Regards,
