Expected Behaviour

An outbound rules of port allocation set to zero with Port allocation set to "Use the default number of outbound ports" should be created.

Actual Behaviour

An outbound rule of port allocation is set to 1024 despite allocated_outbound_ports = 0 was specified in the code, and Port allocation required manual intervention to set it to "Use the default number of outbound ports".

Hi @tanvp112 this seems to be a bug in the provider that 0 is ignored. I've raised a pr #16369 to fix it. And for "Use the default number of outbound ports", unfortunately current Azure API doesn't allow us to do it, but I found an issue already tracking this #11862, would you mind subscribe to it for update

I look forward to the fix in the provider soon, thanks for the prompt replied.
