Opening port to VM to allow access from the internet

Question

Good Day,

I have an issue when attempting to connect to a VM from the internet. On this VM is an App that has a web management interface. When on the VM the port is accessible on TCP 16001, but when attempting to use this with the Public IP address the port appears closed. I have configured access on the Network Security Group (NSG) and also made sure that the host firewall also has a rule that allows remote access to that port. There was a default rule created that allows RDP access to the server within the NSG mirrored the setting but changed the port from 3389 to 16001.

This hasn't worked, looking at MS documentation it not clear, reading forums from 'other sources' (Yes I googled ;-) ). It seems that I need to purchase an additional component from the marketplace a router, or NAT gateway, or firewall or some other security device and another VM to run it on. I am being swamped by the options, costs, etc.

Guess what I need to know first is why the configuration in the NSG is not working? is that the NSG is just for show (act as a firewall internal subnets) and an additional purchase IS REQUIRED to manage NAT?

Thanks in advanced for any info shared.

Thanks

Please ignore the above question. The issue is with me believing what I was told by the app developer. Looking under the hood I saw a reference to 127.0.01. changing this allowed the site to be accessed remotely. The egg on my face will eventually disappear.
