Announcing the public preview of StandardV2 NAT Gateway and StandardV2 public IPs

Microsoft

Nov 18, 2025

In today’s rapidly changing digital landscape, organizations are innovating faster and delivering cloud native experiences at global scale. With this acceleration comes higher expectations: applications must remain always available. An outage in a single availability zone can have a ripple effect on application performance, user experience, and business continuity. To safeguard against zone outages, making your cloud architecture zone resilient isn't an option—it’s a necessity.

A key part of any resilient design is ensuring reliable outbound connectivity. Azure NAT Gateway is a fully managed network address translation service that provides highly scalable and secure internet connectivity for resources inside your virtual networks.

We’re excited to announce the public preview of the StandardV2 SKU NAT Gateway, an evolution of Azure NAT Gateway built for the next generation of scale, performance, and resiliency. StandardV2 NAT Gateway delivers zone redundancy, enhanced data processing limits, IPv6 support, and flow logs all at the same price as the Standard SKU NAT Gateway.

This release also marks the public preview of StandardV2 SKU public IP addresses and prefixes. A new SKU of public IPs that must be used with StandardV2 NAT Gateway. In combination, StandardV2 IPs provide high-throughput connectivity to support demanding workloads.

StandardV2 NAT Gateway is zone resilient and provides dual-stack connectivity.

What’s new in StandardV2 NAT Gateway

Zone redundancy

StandardV2 NAT Gateway is zone-redundant by default in regions with availability zones. Deployed as a single resource operating across multiple zones, StandardV2 NAT Gateway ensures outbound connectivity even if one zone becomes unavailable.

StandardV2 NAT Gateway spans across multiple availability zones in a region.

For example, a virtual machine in zone 2 connects outbound from zones 1, 2, or 3 through a StandardV2 NAT Gateway (as shown in the figure). If zone 1 experiences an outage, existing connections in that zone may fail, but new connections will seamlessly flow through zones 2 and 3—keeping your applications online and resilient. All existing connections through zones 2 and 3 will persist. To learn more, see StandardV2 NAT Gateway zone-redundancy.

In zone down scenarios, new connections flow through the remaining healthy zones with StandardV2 NAT Gateway.

This kind of resiliency is essential for any critical workload to ensure high availability. Whether you’re a global SaaS provider that needs to maintain service continuity for your customers during zonal outages or an e-commerce platform that needs to ensure high availability during peak shopping seasons, StandardV2 NAT Gateway can help you achieve greater protection against zonal outages.

Higher performance

StandardV2 doubles the performance of the Standard SKU, supporting up to 100 Gbps throughput and 10 million packets per second. These enhanced data processing limits are ideal for data-intensive and latency-sensitive applications requiring consistent, high-throughput outbound access to the internet. For more information, see StandardV2 NAT Gateway performance.

StandardV2 public IPs

Alongside NAT Gateway, StandardV2 public IP Addresses and Prefixes are now available in public preview. StandardV2 SKU public IPs are a new offering of public IPs that must be used with StandardV2 NAT Gateway to provide outbound connectivity. Standard SKU public IPs are not compatible with StandardV2 NAT Gateway. See how to deploy StandardV2 public IPs.

IPv6 (dual-stack) support

StandardV2 NAT Gateway now supports dual-stack (IPv4 + IPv6) connectivity, enabling organizations to meet regulatory requirements, optimize performance for modern architectures, and future-proof workloads at internet scale. Each NAT Gateway supports up to 16 IPv4 and 16 IPv6 StandardV2 public IP addresses or prefixes. See IPv6 support for StandardV2 NAT gateway for more information.

Flow logs

With StandardV2, you can now enable flow logs to gain deeper visibility into outbound traffic patterns. Flow logs capture detailed IP-level traffic information, helping you:
