System Requirements for OCI Backup Gateways

Verify that your environment meets the system requirements for deploying the Commvault Cloud backup gateway on Oracle Cloud Infrastructure (OCI).

TCP 443 outbound must be open to access the Commvault Cloud backup service (*.metallic.io). This is only control traffic and not data traffic.
TCP 8403 must be open between the backup gateway and any protected resources.
If the backup gateway and the Oracle resources are deployed in different VCNs or in different accounts, VCN peering is required.
By default, Oracle does not allow internet access to the public subnet unless there is a public IP assigned to that virtual machine (internet gateway). The private subnet has access to the internet by default without a public IP. This is an Oracle limitation, not a Commvault Cloud limitation. For more information, see "Internet Gateway" in Oracle Cloud Infrastructure Documentation.
