I need to set up a gateway between two entities.

One side is running Exch 2000, the other is running GW7.

Groupwise sits behind a firewall on the "Secure" side of the network,
whereas Exchange sits on the "Public" (but not on the Internet) network.

Internet -> | Firewall | -> Exchange | -> Firewall | -> Groupwise /
Novell System

Need to somehow synchronize address books. Installing the Novell client
is NOT an option, on their main Exchange server. We could provide them
with another machine for gateway purposes...Maybe.
