After creating a new Nutanix User VPC, what is needed to allow traffic to flow...

NATed Path Configuration: When using the NATed Path, it is essential to ensure that traffic can flow out of the Flow gateway VM to external networks.

Default Route: Adding a default route on the Nutanix User VPC ensures that all outbound traffic is directed to the appropriate network gateway.

Configuration Steps:

Navigate to the routing settings of the Nutanix User VPC.

Add a default route with the destination of 0.0.0.0/0, pointing to the External Overlay network.

Security Group Settings:

Ensure that the External Flow Gateway Security Group on the External NIC allows outbound traffic.

Ensure that the Internal Flow Gateway Security Group on the internal NIC allows outbound traffic (if needed for internal network flows).

Conclusion: Properly configuring the default route on the Nutanix User VPC enables outbound traffic flow via the NATed Path through the External Overlay network.
