Step 3: Configure Security Group Inbound Rules

Your DAX cluster uses TCP port 8111 for communication, so you will need to authorize inbound traffic on that port. This will allow Amazon EC2 instances in your Amazon VPC to access your DAX cluster.

Note

If you launched your DAX cluster with a different security group (other than default), you will need to perform this procedure for that group instead.

  1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.

  2. In the navigation pane, choose Security Groups.

  3. Choose the default security group. In the Actions menu, choose Edit inbound rules.

  4. Choose Add Rule, and enter the following information:

    • Port Range—type 8111

      Source—type default, and then choose the identifier for your default security group.

    When the settings are as you want them, choose Save.
