Simon,

Thanks.  dnsmasq is getting the queries, you can see them in the log:

Jan 18 16:56:07 datasoft-travel dnsmasq[7973]: query[A] www.cnn.com from
127.0.0.1

But there is neither a reply nor an error message after the query is
received.  "dig www.cnn.com" shows "status: REFUSED".  To be clear, the
queries are originating from the laptop and should be routed through the
bluetooth network connection.  The network connection is there and I can
ping the nameserver over the bluetooth network, but it's having trouble with
the DNS.  I don't think the bluetooth part of it is exactly relevant, but
I'm assuming that somehow disconnecting and reconnecting a bluetooth network
does something different than disconnecting and reconnecting a wifi network.
I think the following commit should solve your issue:

http://thekelleys.org.uk/gitweb/?p=dnsmasq.git;a=commit;h=2675f2061525bc954be14988d64384b74aa7bf8b

Do you have any chance to try a recent git snapshot?

Beniamino

Thanks very much. I applied that commit as a patch against current Ubuntu 16.10 dnsmasq source package and it does in fact fix the problem.

Aaron
