Outbound Traffic via NAT Gateway

For secure and scalable outbound internet access, you can deploy an Azure NAT Gateway on the integration subnet used by your app. The NAT gateway provides a static, public source IP address for all outbound traffic from your app and dramatically increases the number of available SNAT ports, which helps prevent connection exhaustion. To use it, you enable the Route All setting on your app's VNet integration, provision a NAT gateway with a public IP, and then associate that gateway with the integration subnet. This configuration ensures all outbound internet calls from your app originate from the NAT gateway's predictable IP.
