Hello Simon, I have configured upstream server in. Conf file as below server=8.8.8.8@eth0 But somehow dnsmasq not able to read it. Wondering why is it not reading?

Re: [Dnsmasq-discuss] Dnsmasq replying with refuse without forwarding request to upstream server.
Ok. So you're not configuring a server and getting the expected response. Your problem now is to work out why dnsmasq is not reading your configuration. Note that it logs the configured servers ar start up, so that should help debugging. Simon.

Hello Alex, Thank you for your reply. How can I figure out if it's implemented on our platform. I m using 2.80 version. Is there any work around for this?

Re: [Dnsmasq-discuss] Dnsmasq replying with refuse without forwarding request to upstream server.
I get a warning message saying no upstream servers configured when I start the dnsmasq. But in dnsmasq.conf file I have configured upstream server as below server=8.8.8.8@eth0. dnsmasq is running but I get that warning message.

Re: [Dnsmasq-discuss] Dnsmasq replying with refuse without forwarding request to upstream server.
Hey Sunil, I encountered this situation only when dnsmasq didn't have any working upstream server it could forward your query to. Could you please 1. add "log-queries=extra" and "log-facility=/tmp/dnsmasq.log" to your configuration, 2. restart dnsmasq, 3. do the DNS query that ends up in REFUSED, and 4. send us the generated log file Maybe it reveals something of interest.
