Amazon FSx for NetApp ONTAP

Security group rules for FSx for ONTAP

Contributors juliantap

BlueXP creates AWS security groups that include the inbound and outbound rules that BlueXP and FSx for ONTAP need to operate successfully. You might want to refer to the ports for testing purposes or if you need to use your own.

Rules for FSx for ONTAP

The FSx for ONTAP security group requires both inbound and outbound rules. This diagram illustrates FSx for ONTAP networking configuration and security group requirements.

Before you begin

You need to locate the security groups associated with the ENIs using the AWS Management Console.

Steps
  1. Open the FSx for ONTAP file system in the AWS Management Console and click the file system ID link.

  2. On the Network & security tab, click the network interface ID for the preferred or standby subnet.
