+description: |-
+  List forwarding rules in a region of a Google Cloud project.
+---
+
+# google\_compute\_forwarding\_rules
+
+List all networks in a specified Google Cloud project.
+
+## Example Usage
+
+```tf
+data "google_compute_forwarding_rules" "my-forwarding-rules" {
+  project = "my-cloud-project"
+  region  = "us-central1"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `project` - (Optional) The name of the project.
+
+* `region`  - (Optional) The region you want to get the forwarding rules from.
+
+These arguments must be set in either the provider or the resouce in order for the information to be queried.
+
+## Attributes Reference
+
+In addition to the arguments listed above, the following attributes are exported:
+
+* `id` - an identifier for the resource with format projects/{{project}}/region/{{region}}/forwardingRules
+
+* `project` - The project name being queried.
+
+* `region` - The region being queried.
+
+* `rules` - This is a list of the forwarding rules in the project. Each forwarding rule will list the backend, description, ip address. name, network, self link, service label, service name, and subnet.
+
+* `self_link` - The URI of the resource.
