Unable to add a range for port forwarding

[mhdsulaimzed]

resource "cloudstack_port_forward" "head_node_ssh" {
  ip_address_id = cloudstack_ipaddress.head_node_public_ip.id

  forward {
    protocol           = "tcp"
    private_port       = "22"
    public_port        = "22"
    virtual_machine_id = cloudstack_instance.head_node.id
  }

  depends_on = [cloudstack_ipaddress.head_node_public_ip]
}

is there a attribute to specify private and public port start and end port numbers
