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,
