I've got a case where a DNS is not working in the router, I have read some things found on google but I still can't make it work... that's why I'm here and hope you could help.
I issued a debug ip udp to check how the conversion was being made and it seems that the DNS server responds but still does not resolve to the router, I just want to know if it's the DNS or the Router (or both) who are doing this weird behavior.
Here's the output generated with a ping
