ProjectWise Gateway Service is the server module to install for datasource list publishing.

For example, when the ProjectWise Design Integration Server is on a computer that your ProjectWise Explorer clients cannot access, you can install a ProjectWise Gateway Service on a computer that both the clients and the ProjectWise Design Integration Server can access, and then configure the ProjectWise Gateway Service to retrieve the datasource list from the server. ProjectWise Explorer clients on the same subnet as the ProjectWise Gateway Service, or those connected to it using the ProjectWise Network Configuration Settings dialog, will be able to see the ProjectWise Design Integration Server's datasources, as published through the ProjectWise Gateway Service.
