The default TCP TIME_WAIT
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 flag at any time.
Cloud NAT gateways configured with a custom
TIME_WAITvalue 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 |

September 11, 2023
In some cases, it is possible to create multiple NAT gateway configurations that include the same subnet. 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.
