Hello Daniel,

thank you for your reply, although it gave me couple minutes to figure
it out; that dnsmasq serves also as an DNS forwarder. Well, I haven't
thought about this one, because we have everything external. Providing
such option would be great; dnsmasq optionality; yet I'm pretty sure it
would complicate (or even break) a lot of other things.

Ok, at least one mystery got explained. :o)

Thanks,
Zdenek
