Help on recursive set up

There are multiple ways to interpret that question.

Normally, a resolver either uses recursion (with a preconfigured set of 
forwarders) at a given point in resolving a particular name, or it 
follows the NS records in a delegation chain, non-recursively, in order 
to find the answer.

It wouldn't do *both*. A given query can't be recursive and 
non-recursive at the same time.

Possibly you are asking if it's possible for a nameserver which is 
delegated for a particular zone, to forward all queries for names in 
that zone to some other (private/internal) nameserver for resolution. 
The answer to that is "no", since the queries being received by that 
"visible" nameserver are expected to be *non-recursive*, and 
non-recursive queries are never supposed to be forwarded anywhere. You 
might, however, look into some sort of "DNS proxy" solution, if this is 
what you're trying to accomplish.
