For more information, see [NAT64 in Private NAT](https://docs.cloud.google.com/nat/docs/private-nat#nat64). ## September 28, 2026 Feature **Preview** : Cloud NAT gateways for Private NAT support [source-based NAT rules](https://docs.cloud.google.com/nat/docs/nat-rules-overview) for IPv4 addresses. ## June 30, 2026 Feature **Preview** : Cloud NAT gateways for Private NAT support IPv6 to IPv4 network address translation. For more information, see [NAT64 in Private NAT](https://docs.cloud.google.com/nat/docs/private-nat#nat64). ## April 13, 2026 Feature **General Availability** : Cloud NAT gateways for Public NAT support [source-based NAT rules](https://docs.cloud.google.com/nat/docs/nat-rules-overview) for IPv4 addresses. ## March 31, 2026 Announcement The default TCP [`TIME_WAIT`](https://docs.cloud.google.com/nat/docs/tune-nat-configuration#nat-timeouts) timeout for Cloud NAT is scheduled to decrease from 120 seconds to 30 seconds, across all regions, as follows: - **From June 30 to September 29, 2026**: new Cloud NAT gateways will use either the 120-second or 30-second default, depending on when the update is deployed in a specific region. - **On or after September 30, 2026**: all new Cloud NAT gateways in all regions will use the 30-second default. **Impact on gateways** - **New gateways**: after the update is deployed in a region, all new Cloud NAT gateways created in that region will use the 30-second default. This change also applies if a pre-update gateway is deleted and then recreated. - **Existing gateways** : Cloud NAT gateways created before the regional update will retain the 120-second default. You can adjust this value by using the [--tcp-time-wait-timeout](https://docs.cloud.google.com/nat/docs/tune-nat-configuration#change-conn-timeouts) flag at any time. Cloud NAT gateways configured with a custom `TIME_WAIT` value aren't affected and will continue to use your configured custom value. The following table outlines the applicable default timeout for new gateways throughout the deployment timeline. | Gateway type | Default timeout (before June 30) | Default timeout (June 30---September 29) | Default timeout (on or after September 30) | |---|---|---|---| | New | 120 seconds | 30 or 120 seconds | 30 seconds | ## October 21, 2025 Feature **General Availability** : Private NAT supports Cloud Run.

For some of these configurations, VMs that are attached to that subnet are not allocated NAT ports, and therefore can't access resources on the internet. For more information about this issue and a workaround, see [VMs can't reach the internet](https://docs.cloud.google.com/nat/docs/troubleshooting#vms-no-internet-access). ## August 22, 2023 Feature Cloud NAT support for [inter-VPC communication](https://docs.cloud.google.com/nat/docs/set-up-private-nat) is in **Preview**. ## August 06, 2023 Feature Cloud NAT support for [Standard Tier egress](https://docs.cloud.google.com/nat/docs/set-up-manage-network-address-translation#allocate-tier-specific-ip-nat) is in **General Availability**. ## May 30, 2023 Feature Cloud NAT support for [Standard Tier egress](https://docs.cloud.google.com/nat/docs/ports-and-addresses) is available in **Preview**. ## February 17, 2022 Feature [Dynamic port allocation](https://docs.cloud.google.com/nat/docs/ports-and-addresses#dynamic-port) for Cloud NAT is in **General Availability**. ## November 18, 2021 Feature [Cloud NAT rules](https://docs.cloud.google.com/nat/docs/nat-rules-overview) are in **General Availability**. ## September 30, 2021 Feature [Dynamic port allocation](https://docs.cloud.google.com/nat/docs/ports-and-addresses#dynamic-port) for Cloud NAT is available in **Preview**. ## August 02, 2021 Feature [Cloud NAT rules](https://docs.cloud.google.com/nat/docs/overview#nat-rules) are available in **Preview**.
