Hi all, a customer is using the following versions: Natural 6.2.3 Natural RPC 6.1.1 patch level 0 EntireX Broker Stub 7.3.2, patch level=00, Highest API Supported=9 We have the following requirements: 1. Client and server have to communicate using ONC RPC protocol (Open Network Computing Remote Procedure Call) 2. Information has to be encripted using “tunnelling” Are these requirements supported with these versions? How do we have to configure EntireX Broker to ensure the security requirements (in client and server side)? Thank you! ---

Natural/EntireX are not using ONC RPC but a proprietary RPC implementation. For encryption SSL is supported and recommended. ---
