EntireX configuration

We are installing EntireX in our environment and this is a new thing on our site. We will do a three tier connection i.e frontend(VB)->Windows 2003 with the broker and Mainframe(VSE). We are using Adabas/Natural.
Is it possible to bypass the Windows server and what could be the implications?

not quite clear what you are asking to do. You could put Broker on the mainframe and call Broker from the VB client, removing Broker on Windows.

Are your VB clients calling Broker directly or are they passing a remote request to the Windows server, which does the Broker call?

We have decided to bypass the windows server and access the broker directly on the mainframe. Now we have to create Natural RPC to access the broker.
