WhenFlow Virtual Networking (FVN)is enabled for an NC2 cluster, Nutanix orchestrates the creation of aTransit VPCto handle traffic between the overlay and external networks. The core subnet created within this Transit VPC is namedoverlay-external-subnet-nonat. This subnet is critical as it serves as the entry and exit point for traffic that should not be subjected to address translation, such as traffic moving between the cloud overlay and an on-premises data center via a Transit Gateway or VPN. While administrators can manually add a NAT-enabled subnet later, the " nonat " variant is the primary default used to ensure that internal corporate communications remain transparent across the hybrid cloud boundary.
