This *should* work. When a network is isolated, we add "no-resolv" to
the dnsmasq conf file to prevent having unresolvable requests forwarded
to the hosts listed in /etc/resolv.conf on the host, but since
<forwarder> is handled by adding a server= option to dnsmasq.conf, that
should still work (I haven't tried it though).

The would be nice, but there is no support for it.
