[Unbound-users] Problem resolving private domains

Hello

we have Unbound 1.4.6 as caching resolver for our internal network  
which in turn forward queries to Bind 9.7 at the border. It works fine  
except for our remote location (VPN) which uses 10.2.0.0/16 as  
internal network.

We have set

	private-domain: "domain1.de"
	private-domain: "domain2.cz"

	local-zone: "10.in-addr.arpa" nodefault
	local-zone: "168.192.in-addr.arpa" nodefault

forward-zone:
  	name: "."
  	forward-addr: <IP-address-of-Bind97>

If have checked that Bind 9.7 can resolve both fine but Unbound only  
resolves "domain1.de" internal addresses correctly which are located  
in 10.1.0.0/16 and not "domain2.cz" which are at 10.2.0.0/16. For  
domain2.cz we always get timeout from Unbound despite the fact the  
Unbound has asked Bind and have got the correct result?

Thanks for any help
