We have a huge intranet with internet-connectivity via an
We also have an internal-web-cache-server and split-dns.
Now we discuss on how to configure split-dns.
Version 1: with forwarding
The internal dns-server ( not identical with the firewall-computer) has
a forwarder-statement and slave-statement to the external-dns-server in

It can only be done by the proxy at the firewall-computer. So the
application at the inside-pc must work with proxy and
can not resolve internet-adresses by itself.
Which configuration is better ?
Will everything work with version 2 (no forwarding) ?
It is even more complicated because we will have to
