New Blog | Private IP DNAT Support and Scenarios with Azure Firewall

By Gustavo Modena

 

Introduction

Azure Firewall is a cloud native security service to protect your workloads running in Azure. It is a stateful firewall as a service with built-in high availability and auto scale. Azure Firewall supports three rule types: DNAT, Network and Application rules.

 

In this blog, we will talk about enhancements to the DNAT rules. Up until recently, DNAT rules only was only supported on the Firewall Public IP addresses, mostly used for incoming traffic. In this release, we have enhanced DNAT scenario to support port translation on Azure Private IP (VIP). This capability helps with connectivity between overlapped IP networks, which is a common scenario for enterprises when onboarding new partners to their network or merging with new acquisitions. DNAT on Private IP is also relevant for hybrid scenarios (connecting on-premises datacenters to Azure), where DNAT bridges the gap, enabling communication between private resources over non-routable IP addresses.
