SAP Cloud Connector -> From ERP to HCI/C4C

Hi,

We installed Sap Cloud Connector and for Inbound is OK (C4C -> HCI -> SCC -> ERP).

We would like to use SCC for outbound (ERP -> SCC -> HCI -> C4C). is it possible?

In the documentation we see SCC like a single Gateway between Cloud and on-premise but in SAP ERP we don't have transcation to configure SCC but only Proxy Server.

Our customer haven't a Proxy and Customer would not publish or permit traffic directly from ERP to -> C4C.

So:

1) is it possible the flow ERP-> SCC-> HCI-> C4C? In wich transaction on ERP I configure SCC

2) otherwise shall we install a Proxy Server? ERP -> Proxy -> HCI -> C4C

3) Can SCC be a Proxy or is it only a reverse proxy?

Thank you

Mario
