I need to implement CSG 3.0 to work with Presentation Server 4.0 in our DR lab and need to figure out how many servers I need to designate. In past we had STA running on a separate server. I think it is on Presentation 4.0 now by default. So do I just point to Presenation Server as the STA in SCG configs.? Also, if I combine CSG and a web interface on the same server, does it matter what verson of web interface I use. Does it have to be web inetrface 3.0 if I use SecureGateway 3.0? Thank you in advance.
