Ubuntu 13.10 (Saucy) included dnsmasq 2.66 or so. In dnsmasq 2.69 an important change was made which may be the cause of your problem. This change affects Ubuntu 14.10 and later, but not Ubuntu 14.04LTS (Trusty) which shipped with dnsmasq 2.68-1. The change is mentioned in the changelog (quoted below) and it should be obvious how this might be affecting you. Read the new dnsmasq manpage for a longer description of the "local-service" option.
dnsmasq (2.69-1) unstable; urgency=low * New upstream. * Set --local-service. (closes: #732610) This tells dnsmasq to ignore DNS requests that don't come from a local network. It's automatically ignored if --interface --except-interface, --listen-address or --auth-server exist in the configuration, so for most installations, it will have no effect, but for otherwise-unconfigured installations, it stops dnsmasq from being vulnerable to DNS-reflection attacks. -- Simon Kelley <si...@thekelleys.org.uk> Tue, 4 Feb 2014 16:28:12 +0000 ** Changed in: dnsmasq (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1414887 Title: dns query from localnetwork are blocked To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/1414887/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
