You can create either Inbound or Outbound cloud forwarder based on the requirement. Outbound forwards from cloud to outside the cloud. Inbound resolves the queries from the cloud which are coming from the outside the cloud.
You create either an Inbound or Outbound cloud forwarder based on the requirement:
Outbound to forward from cloud to outside (another cloud provider).
Inbound to resolve the queries from the cloud which are coming from the outside the network.
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.
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.
