[Unbound-users] Only forward specific query to the Forwarding zone

Not sure if i can ask my question here, since i suppose it's more general
than just unbound related.

I'm trying to set up a system that i tought was easy.

I've a lan, with a unbound dns resolving lan.domain.net and everything on
the internet, for the local users.
Everything works fine at that point.

Here is a snippet of my configuration file

include: "/var/unbound/etc/zone-lan.conf"

that contains

local-zone: "lan.domain.net" static
local-data: xxxxxxx

Now, my goal is to forward all query for a different subdomain (
virtu.domain.net) to a different dns servers and ONLY that sort of query.

Here's the related configuration part

local-zone: "virtu.domain.net" transparent
name: "virtu.domain.net."

The thing is, all sort of query are forwarded to that server (see them with
tcpdump, dropbox, gmail...), and some are not (vm1.virtu.domain.net).
I rate as working 80% of the time.

Is the unbound part of my configuration ok ?

Another problem is that some windows got the virtu.domain.net as the
primary dns server...

The dhcp configuration is:

shared-network lan.domain.net {

option  domain-name "lan.domain.net";
option  domain-name-servers;

Thank you for your help and apology for my english.
