Inside vWAN routing affinity

[coding-totoro]

Hi,

When running this: https://github.com/40net-cloud/fortinet-azure-solutions/blob/main/FortiGate/AzureVirtualWAN/doc/insidevwan-sdwan.md

The traffic leaving the vWAN NVA is not sticky at the internal load balancer causing basic things like admin.google.com to not work as google detects multiple public ips in the traffic, same for most sites with MFA, they sign out the user as the IP is flip flopping between nodes.

I suspect its due to this: https://learn.microsoft.com/en-us/azure/load-balancer/distribution-mode-concepts and session affinity was left in default.

Can you advise on how this traffic flow is intended to work?
