I just setup a Fortigate NGFW in a VM in Azure, but I realized I would be adding 2 additional layers of NAT in front of my load-balaced web servers. Meaning, now (ELP=External Load Balancer;PIP=Public IP; ILB=Internal Load Balancer): ELB PIP --->(NAT)---> VM internal IP with firewall: Firewall PIP --->(NAT)---FW internal IP--->(NAT)---ILB--->(NAT)---VM internal IP
I don't think triple NAT can be considered an optimal setup. Am I just doing this wrong?

It's not ideal but something it's the law of the jungle and you have no other options. Ideally you want NAT simplified but even in AWS with EIP, you have the same issues sometimes.
It make gathering logging and details about session flow harder to track also.
