Controlling Access to File Storage
On Private Cloud Appliance, before you can mount a file system, you must configure security rules to allow traffic to the mount target's VNIC using specific protocols and ports.
Security rules enable traffic for the following protocols:
- 
Open Network Computing Remote Procedure Call (ONC RPC) rpcbind utility protocol 
- 
Network File System (NFS) protocol 
- 
Network File System (MOUNT) protocol
