I've pushed dnsmasq-2.64rc2 at http://www.thekelleys.org.uk/dnsmasq/release-candidates/dnsmasq-2.64rc2.tar.gz This adds an extra check on which interfaces router advertisements go out on, and the SetDomainServers DBus method. This will become 2.64 final very soon unless any problems are reported. Cheers, Simon.
