Step 4. Update Security Group

To allow inbound traffic to the backup appliance from the on-premises network, update the security group for the appliance VPC:

1. In the VPC console, navigate to Security > Security Groups.
2. In the Security Group list, choose the default security group and click Actions > Edit Inbound Rules.
3. In the Edit inbound rules wizard, click Add rule, add a new inbound rule for the SSH, RDP and ICMP protocols, and click Save rules.
