# cloudstack\_firewall

Creates firewall rules for a given IP address.

## Example Usage

```
resource "cloudstack_firewall" "default" {
  ipaddress = "192.168.0.1"

  rule {
    source_cidr = "10.0.0.0/8"
    protocol = "tcp"
    ports = ["80", "1000-2000"]
  }
}
```

## Argument Reference

The following arguments are supported:

* `ipaddress` - (Required) The IP address or ID for which to create the firewall
    rules. Changing this forces a new resource to be created.

* `managed` - (Optional) USE WITH CAUTION! If enabled all the firewall rules for
    this IP address will be managed by this resource. This means it will delete
    all firewall rules that are not in your config! (defaults false)

* `rule` - (Optional) Can be specified multiple times. Each rule block supports
    fields documented below. If `managed = false` at least one rule is required!

The `rule` block supports:

* `source_cidr` - (Required) The source CIDR to allow access to the given ports.

* `protocol` - (Required) The name of the protocol to allow. Valid options are:
    `tcp`, `udp` and `icmp`.

* `icmp_type` - (Optional) The ICMP type to allow. This can only be specified if
    the protocol is ICMP.

* `icmp_code` - (Optional) The ICMP code to allow. This can only be specified if
    the protocol is ICMP.

* `ports` - (Optional) List of ports and/or port ranges to allow. This can only
    be specified if the protocol is TCP or UDP.

## Attributes Reference

The following attributes are exported:

* `id` - The IP address ID for which the firewall rules are created.
