With Cloud NGFW for Azure, you can access core firewall capabilities from Palo Alto Networks, such as App-ID and Advanced URL Filtering. It provides threat prevention and detection through cloud-delivered security services and threat prevention signatures. The deployment model in this article uses the reverse proxy and web application firewall (WAF) functionality of Application Gateway by using the network security capabilities of Cloud NGFW for Azure.

To help secure ingress connections, a Cloud NGFW for Azure resource supports Destination Network Address Translation (DNAT) configurations. Cloud NGFW for Azure accepts client connections on one or more of the configured public IP addresses and performs the address translation and traffic inspection. It also enforces user-configured security policies.

For web applications, you benefit from using Application Gateway as both a reverse proxy and a load balancer. This combination offers the best security when you want to secure both web-based and nonweb workloads in Azure and on-premises ingress connections. Cloud NGFW for Azure allows the use of a single public IP address of Application Gateway to proxy the HTTP and HTTPS connections to many web application back ends. Any non-HTTP connections should be directed through the Cloud NGFW for Azure public IP address for inspection and policy enforcement.

After you deploy and configure the infrastructure, you must apply a security policy to Cloud NGFW for Azure that allows the connection from the Application Gateway virtual network. Application Gateway proxies the client's TCP connection and creates a new connection to the destination specified in the back-end target. The source IP of this connection is the private IP address from the Application Gateway subnet. Configure the security policy accordingly, by using the Application Gateway virtual network prefix to ensure that it's treated as the inbound flow. The original source IP of the client isn't preserved at layer 3.
