Cloud Network Address Translation | Google Cloud

Learn how to protect your outbound connections without public IPs

Cloud NAT

Cloud NAT

Cloud-first high performance network address translation

Cloud NAT provides fully managed, software-defined network address translation support for Google Cloud.

Features

High performance network address translation

Cloud NAT delivers high performance, reliability and scalability, avoiding the need for middle proxies. It lets you restrict inbound communications to your app instances while allowing them to have outbound communications to the internet without using public IPs.

Dynamic port allocation

Dynamic Port Allocation (DPA) feature enable Cloud NAT to scale up and down port allocations depending on-demand while providing operator controls to set minimum and maximum port limits.

Flexible IP address allocation

Choose your NAT IP allocation based on your network requirements. Manual mode gives you full control when specifying IPs, while Auto mode enables the NAT IPs to be allocated and scaled automatically

Simplified deployment and operations

A single Cloud NAT gateway can provide NAT for all subnets in a VPC region and be configured to support multiple NAT IP addresses. Cloud NAT simplifies application deployment and operation, requiring no changes to networking, forwarding, or routing configurations.

Unparallelled network performance

Autoscale your NAT operations with minimal impact to throughput and latency and a 99.99% SLA.

How It Works

To use Cloud NAT, you’ll first create a NAT gateway. Then you’ll be able to configure the NAT policies to safeguard outbound internet connections to GCE and GKE workloads from external threats

Common Uses

Public NAT

Private NAT for Network Connectivity Center spokes

Private NAT enables private-to-private translations across Google Cloud networks and other on-premises or cloud provider networks. Inter-VPC NAT lets you create a private NAT gateway that works in conjunction with Network Connectivity Center Virtual Private Cloud (VPC) spokes to perform network address translation (NAT) between VPC networks.
