Azure webserver access from load balancer and palo alto firewall

Hello Tech Gurus,

I am very new to azure and have knowledge on palo alto on-prem firewalls,

I have the below requirement where I need to build the network in azure cloud

Laptop--> Public Load balancer --> Palo alto FW --> Webserver

But when I configured the load balancer back end pool as palo alto untrust port and open https for management, I am not able to browse the webserver, instead of webserver traffic is hitting on the firewall management portal.

Can you please suggest how can the traffic hitting on untrust port will be forward to webserver through firewall.

Thankyou

Sudhakar

Best practice is to setup an inbound NAT on a port other than TCP/80 or TCP/443. For instance, use an inbound nat on port TCP/8888 that NATs to 443 with a destination of your back-end server. You can also check the reference architecture guide well.
