Hello,

We have setup Azure Application Gateway which is forwarding traffic to our on-premises server, and its working great. My question is what IP ranges or IP addresses can we setup in our on-prem firewall to lock down so that we are only responding to Azure requests requests and nothing else.

    Hi, Application Gateway will act as a reverse proxy. So you will need to whitelist Application Gateway subnet in your On-Premises to accept traffic and block rest of the IPs.
