Please run tcpdump -i wan udp port 53 -c 1000 -w /tmp/whatdns.pcap
(WAN is the device used as WAN connection, sometimes eth0.2 or eth1.2)
Then open file in wireshark, try to get sense from it.
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </>

root@OpenWrt:~# tcpdump -i wan udp port 53 -c 1000 -w /tmp/whatdns.pcap
tcpdump: wan: No such device exists
(No such device exists)
my wan named is wan (eth1), so that is correct
It is eth1 in your configuration
i.e tcpdump -i eth1 -w /tmp/dns.pcap -c 1000 udp port 53
Try to make sense of packet capture. It is kind of private, best to not post anywhere.
it's on the local network only, so no real sense, as you can see due to no wifi features
Do you have any Maven/Artifactory on your LAN?
