Description

Azure Virtual NAT (network address translation) is a fully managed and highly resilient PaaS offering by Azure that simplified the outbound connectivity for virtual networks. The outbound connectivity of the virtual network can be defined for one or multiple subnets on a virtual network using single Public IP or public IP prefix resource or a combination of both. The traffic is routed through the NAT gateway, once configured, all without any custom route tables.

If an application demands to have a static IP or set of IPs when sending traffic to the internet or external endpoints, Azure NAT is the solution that lets you achieve those requirements easily. Although similar functionality can be achieved using a load balancer, the NAT gateway makes it a breeze to configure and manage the traffic flow without much effort. NAT uses port NAT (PNAT) and is the recommended solution when deploying solutions in Azure.

In this hands-on lab, you will learn to configure Azure Function behind a NAT gateway to restrict the outbound IP address.
