Environment

SAP Datasphere

Resolution

In Datasphere, System -> About -> More section, the information of "Outbound IP Address" and "HANA IP Address" can be found.

There are 3 kinds of IP addresses used in Datasphere:

Outbound IP Address of Flows Cluster

This is the "Outbound IP Address" in "About" popup.

In other words, "Outbound IP Address" is NOT the outbound IP addresses of the Datasphere's HANA Cloud,
but instead the outbound IP addresses of Datasphere's Flows Cluster.
NAT IP Addresses of Datasphere's HANA Cloud Database

Datasphere's HANA Cloud Database NAT IPs (egress, for outgoing requests) are the "HANA IP Address" in "About" popup.

They are used in below 2 scenarios:

- The customer connects a REST remote source to his HANA Cloud instance through SDI (for example, OdataAdapter). Then he will notice that the REST remote source is accessed using one of the NAT / egress IPs
- The customer connects performs connects a remote source using SDA to his HANA Cloud instance. Then the connection uses the NAT / egress IP in case they don't use the Cloud Connector.
LB IP Addresses of Datasphere's HANA Cloud Database

The LB IP addresses (ingress, for incoming requests) of the Datasphere's HANA Cloud Database are NOT listed in "About" popup at this moment.

They are required for any connection established to SAP HANA Cloud including SDI DP Agent/Cloud Connector.
Most of connections to SAP HANA Cloud are through the LB/ingress IPs. (Exception: 2 scenarios with NAT IPs explained the above)
