Yes.
first remove the global "forward statements", they make no sense in most
applications. Secondly define a "forward zone" to your office nameserver
( i assume your office runs split-dns, possibly using views, giving out
Interhet-addresses to anyone on Internet, and handing out 1918-addresses
to anyone on inside. You would like to belong to the "insiders" i assume.
