Azure NAT Gateway
Provide highly reliable, secure, and scalable outbound connectivity to the internet.
Overview
Simplify outbound internet connectivity for virtual networks
NAT Gateway is a fully managed service that securely routes internet traffic from a private virtual network with enterprise-grade performance and low latency. With built-in high availability using software-defined networking, you can easily configure, scale, and deploy outbound connectivity for dynamic workloads with NAT Gateway.
- Start securely connecting outbound to the internet with enterprise-grade performance and low latency by deploying a NAT (network address translation) gateway resource. With just a few clicks of a button, assign your NAT gateway to subnets within a single virtual network and static public IP addresses. NAT Gateway assumes the default route to the internet once configured to a subnet, with no traffic routing configurations required.
- Scale out internet connectivity for your virtual networks and avoid common connection issues such as SNAT (source network address translation) port exhaustion. Assign multiple public IP addresses or prefixes to a NAT gateway resource to automatically scale outbound connectivity. All SNAT ports provided by NAT gateway public IPs are available on-demand to subnets attached to NAT gateway.
- When you associate a NAT gateway resource to subnets in a virtual network, compute resources don't need public IP addresses to connect to the internet and can remain private. Internet-originated traffic cannot pass inbound through a NAT gateway; only outbound and response traffic is allowed.
- NAT Gateway is a software-defined networking service fully managed by Azure. It has built-in redundancy to ensure high availability and resiliency to service outages. NAT Gateway does not count toward the network bandwidth of your private network compute resources and will not impact their performance.
