Refer to the sections below for details on some common issues seen when load balancing the IBM COS workload.

Connections Rejected

When using a non-default TCP port or offloading for IBM COS services, you must ensure the Real Server port is correct. This is a common mistake when configuring the Real Servers when the Virtual Services port is different from the Real Server port. See the table in the IBM Cloud Object Storage section of this document for the required Real Server ports for COS.

Source/Client IP Visibility

If the client source IP address is required for audit logging, configure your load balancer so that it passes the requests through with the original requesting IP address.
