[Dnsmasq-discuss] dnsmasq: failed to send packet: Network is unreachable

[Paul Marley]

Hello,

I am running Ubuntu 22.04 server with Dnsmasq version 2.86. Dnsmasq is set up to handle DNS and DHCP. I have a Windows client that connects and receives a DHCP address. The client is able to browse without issue, however, after some time (time varies) the client loses the ability to do name resolution. Ping to an IP address still works but not to a host name. The issue persists until dnsmasq is restarted. We have not been able to replicate the same issue on Mac or Linux clients.

Is this a known bug? Might there be something wrong with my configuration? Can you recommend any resources to help me resolve the issue?

Thanks,
Paul
