internal view - forward problem

[Sten Carlsen]

I assume a few things:

1 - the external view is a slave of the master.

2 - the internal view is master for the internal zone (who else would 
know the facts?)

3 - the name of the zone (including subdomain names) in the internal 
view is the same as in the external view?

If this is your configuration, the internal view is master and therefore 
authoritative. So if the name is not in its data, the name can safely be 
assumed to NOT exist, if it did, the internal view would know about it 
as it is authoritative. Following from this, the internal view will not 
forward the query, but will reply that it does not exist.
I assume this is what you see?

A server (or view) can not be master (= authoritative) and at the same 
time recognize that it does not have all data and forward a query to 
someone else.

I see two options:

1 - If you control the master, change its files to include a file with 
the data you want to be visible in the internal view and then include 
this file in the internal view.

2 - change the name of the internal zone to xxx.domain.com (change xxx 
to whatever you like) then you can make the internal view a slave of the 
external master and so have that data available also internally.
