My first thought is that it's probably replying to the wrong
interface: link local addresses can't be routed: you have to specify
the interface they're connected to. This insight came late to me, and
there's a chance that the dnsmasq code is still messing it up. I'll
take a closer look in the next day or two.

Cheers,

Simon.
