Can't create dnat rule for all ports

[Juanito87]

Hi there,

Thank you for opening an issue. Please note that we try to keep the Terraform issue tracker reserved for bug reports and feature requests. For general usage questions, please see: https://www.terraform.io/community.html.

Terraform Version

Run terraform -v to show the version. If you are not running the latest version of Terraform, please upgrade because your issue may have already been fixed.
terraform v0.14.5

Affected Resource(s)

Please list the resources as a list, for example:

• huaweicloud_compute_instance

• huaweicloud_cce_node

• huaweicloud_nat_dnat_rule
  If this issue appears to affect multiple resources, it may be an issue with Terraform's core, so please mention this.

Terraform Configuration Files

# Copy-paste your Terraform configurations here - for large Terraform configs,
# please use a service like Dropbox and share a link to the ZIP file. For
# security, you can also encrypt the files using our GPG public key.

This config works:

resource "huaweicloud_nat_dnat_rule" "all-ports" {
    floating_ip_id        = huaweicloud_vpc_eip.eip_testing-in.id
    nat_gateway_id        = huaweicloud_nat_gateway.maingw.id
    private_ip            = huaweicloud_compute_instance.demo-2.access_ip_v4
    protocol              = "tcp"
    internal_service_port = 22
    external_service_port = 22
}

This one does not:

resource "huaweicloud_nat_dnat_rule" "all-ports" {
    floating_ip_id        = huaweicloud_vpc_eip.eip_testing-in.id
    nat_gateway_id        = huaweicloud_nat_gateway.maingw.id
    private_ip            = huaweicloud_compute_instance.demo-2.access_ip_v4
    protocol              = "any"
    internal_service_port = 0
    external_service_port = 0
}

Debug Output

Panic Output

If Terraform produced a panic, please provide a link to a GitHub Gist containing the output of the crash.log.

Expected Behavior

What should have happened?

It should create a dnat rule redirecting all ports, like in the gui.

Actual Behavior

What actually happened?
It says tha no internal or external port configured and fails.

Steps to Reproduce

Please list the steps required to reproduce the issue, for example:

1. terraform apply

2. Plan a dnat rule that uses protocol "any" and ports 0 (internal and external) for a ecs.

3. apply it

4. Error asking for external_service_port requiered.

Important Factoids

Are there anything atypical about your accounts that we should know? For example: Batch processing multiple resources? Poor network quality?
