You create either an Inbound or Outbound cloud forwarder based on the requirement as follows:
Outbound to forward DNS queries from one cloud provider to another.
Inbound where a NIOS-X Server responds to queries from a private cloud.
After you have completed the tasks listed in Prerequisites for Cloud Forwarders, complete the following steps to create a cloud forwarder:
Go to Configure > Networking > DNS > Cloud Forwarders.
Click Create and select AWS, Azure or GCP.
Configure the following:
Name: Specify a name for the cloud forwarder.
Description: Provide a brief description.
Inbound/Outbound: Select Inbound/Outbound based on the requirement. Consider the following two scenarios before configuring a cloud forwarder as Inbound or Outbound:
Inbound Cloud Forwarder: NIOS-X Server responds to queries from a private cloud (AWS, Azure, or GCP).
Outbound Cloud Forwarder: Forward DNS queries from one cloud provider to another. For example, you can forward DNS queries from AWS to Azure and vice-versa. Cloud to cloud forwarding is only supported for AWS and Azure.
VPC/VNET: Select the VPC/VNET from the drop-down. Azure and AWS only support a single VPC/VNET. GCP supports multiple VPC/VNETs.
Subnet Address: Select the subnet and use the arrow icon (>>) to move it from Available to Selected. Azure only supports a single subnet and the subnet chosen must be used exclusively for the cloud forwarder. AWS supports multiple subnets. No subnet is chosen for GCP as GCP uses a standard network to source forwarded DNS traffic (35.199.192.0/19).
Click Save & Close.
