# google\_compute\_router\_nat
Manages a Cloud NAT. For more information see
[the official documentation](https://cloud.google.com/nat/docs/overview)
and
[API](https://cloud.google.com/compute/docs/reference/rest/beta/routers).
## Example Usage
A simple NAT configuration: enable NAT for all Subnetworks associated with
the Network associated with the given Router.
```hcl
resource "google_compute_network" "network" {
name = "my-network"
}
resource "google_compute_subnetwork" "subnetwork" {
name = "my-subnet"
network = "${google_compute_network.network.self_link}"
ip_cidr_range = "10.0.0.0/16"
region = "us-central1"
}
resource "google_compute_router" "router" {
name = "router"
region = "${google_compute_subnetwork.foobar.region}"
network = "${google_compute_network.foobar.self_link}"
bgp {
asn = 64514
}
}
resource "google_compute_router_nat" "simple-nat" {
name = "nat-1"
router = "${google_compute_router.router.name}"
region = "us-central1"
nat_ip_allocate_option = "AUTO_ONLY"
source_subnetwork_ip_ranges_to_nat = "ALL_SUBNETWORKS_ALL_IP_RANGES"
}
```
A production-like configuration: enable NAT for one Subnetwork and use a list of
static external IP address.
```hcl
resource "google_compute_network" "network" {
name = "my-network"
}
resource "google_compute_subnetwork" "subnetwork" {
name = "my-subnet"
network = "${google_compute_network.network.self_link}"
ip_cidr_range = "10.0.0.0/16"
region = "us-central1"
}
resource "google_compute_router" "router" {
name = "router"
region = "${google_compute_subnetwork.foobar.region}"
network = "${google_compute_network.foobar.self_link}"
bgp {
asn = 64514
}
}
resource "google_compute_address" "address" {
count = 2
name = "nat-external-address-${var.count}"
region = "us-central1"
}
resource "google_compute_router_nat" "advanced-nat" {
name = "nat-1"
router = "${google_compute_router.router.name}"
region = "us-central1"
nat_ip_allocate_option = "MANUAL_ONLY"
nat_ips = ["${google_compute_address.*.address.self_link}"]
source_subnetwork_ip_ranges_to_nat = "LIST_OF_SUBNETWORKS"
subnetwork {
name = "${google_compute_subnetwork.subnetwork.self_link}"
}
}
```
## Argument Reference
The following arguments are supported:
* `name` - (Required) A unique name for Cloud NAT, required by GCE. Changing
this forces a new NAT to be created.
* `router` - (Required) The name of the router in which this NAT will be configured.
Changing this forces a new NAT to be created.
* `nat_ip_allocate_option` - (Required) How external IPs should be allocated for
this NAT. Valid values are `AUTO_ONLY` or `MANUAL_ONLY`. Changing this forces
a new NAT to be created.
* `source_subnetwork_ip_ranges_to_nat` - (Required) How NAT should be configured
per Subnetwork. Valid values include: `ALL_SUBNETWORKS_ALL_IP_RANGES`,
`ALL_SUBNETWORKS_ALL_PRIMARY_IP_RANGES`, `LIST_OF_SUBNETWORKS`. Changing
this forces a new NAT to be created.
- - -
* `nat_ips` - (Optional) List of `self_link`s of external IPs. Only valid if
`nat_ip_allocate_option` is set to `MANUAL_ONLY`. Changing this forces a
new NAT to be created.
* `subnetwork` - (Optional) One or more subnetwork NAT configurations. Only used
if `source_subnetwork_ip_ranges_to_nat` is set to `LIST_OF_SUBNETWORKS`. See
the section below for details on configuration.
* `min_ports_per_vm` - (Optional) Minimum number of ports allocated to a VM
from this NAT config. If not set, a default number of ports is allocated to a VM.
Changing this forces a new NAT to be created.
* `udp_idle_timeout_sec` - (Optional) Timeout (in seconds) for UDP connections.
Defaults to 30s if not set. Changing this forces a new NAT to be created.
* `icmp_idle_timeout_sec` - (Optional) Timeout (in seconds) for ICMP connections.
Defaults to 30s if not set. Changing this forces a new NAT to be created.
* `tcp_established_idle_timeout_sec` - (Optional) Timeout (in seconds) for TCP
established connections. Defaults to 1200s if not set. Changing this forces
a new NAT to be created.
* `tcp_transitory_idle_timeout_sec` - (Optional) Timeout (in seconds) for TCP
transitory connections. Defaults to 30s if not set. Changing this forces a
new NAT to be created.
* `project` - (Optional) The ID of the project in which this NAT's router belongs. If it
is not provided, the provider project is used. Changing this forces a new NAT to be created.
* `region` - (Optional) The region this NAT's router sits in. If not specified,
the project region will be used. Changing this forces a new NAT to be
created.
The `subnetwork` block supports:
* `name` - (Required) The `self_link` of the subnetwork to NAT.
* `source_ip_ranges_to_nat` - (Optional) List of options for which source IPs in the subnetwork
should have NAT enabled. Supported values include: `ALL_IP_RANGES`,
`LIST_OF_SECONDARY_IP_RANGES`, `PRIMARY_IP_RANGE`
* `secondary_ip_range_names` - (Optional) List of the secondary ranges of the subnetwork
that are allowed to use NAT. This can be populated only if
`LIST_OF_SECONDARY_IP_RANGES` is one of the values in `source_ip_ranges_to_nat`.
## Import
Router NATs can be imported using the `region`, `router`, and `name`, e.g.
```
$ terraform import google_compute_router_nat.my-nat us-central1/router-1/nat-1
```
