A server with two addresses: (x) and (y). The server's DNS makes
external queries to forwarder (z). If a client's dns is configured to
(x), the server forwards the client's query on behalf of (x) to (z).
If the client's dns is set to (y), the forwarding query is made by the
server from (y). That is the way in Netware 5+. IMHO, it's not always
convenient. For example, the NW4.11 dns always makes forwarding
queries on behalf of the first configured ip address on the server.

Is there a way to make a dns server to make forwarding queries from an
address configured somewhere?
