+# aws\_customer\_gateway
+
+Provides a customer gateway inside a VPC. These objects can be connected to VPN gateways via VPN connections, and allow you to establish tunnels between your network and the VPC.
+
+## Example Usage
+
+```
+resource "aws_customer_gateway" "main" {
+    bgp_asn = 60000
+    ip_address = "172.83.124.10"
+    type = ipsec.1
+    tags {
+        Name = "main-customer-gateway"
+    }
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `bgp_asn` - (Required) The gateway's Border Gateway Protocol (BGP) Autonomous System Number (ASN).
+* `ip_address` - (Required) The IP address of the gateway's Internet-routable external interface.
+* `type` - (Required) The type of customer gateway. The only type AWS
+  supports at this time is "ipsec.1".
+* `tags` - (Optional) Tags to apply to the gateway.
+
+## Attribute Reference
+
+The following attributes are exported:
+
+* `id` - The amazon-assigned ID of the gateway.
+* `bgp_asn` - The gateway's Border Gateway Protocol (BGP) Autonomous System Number (ASN).
+* `ip_address` - The IP address of the gateway's Internet-routable external interface.
+* `type` - The type of customer gateway.
+* `tags` - Tags applied to the gateway.
