Public and Private IP on same VM NIC

Question

If I need users to access a server app on my VM from the WAN, and also need that same VM to be accessed from another VM on my Azure Vnet, can I (or should I) create a static public IP and assign it to the same NIC with the private internal IP? When I create and assign the public static IP to the NIC will it simply replace the already assigned private IP on that NIIC, or let me create two?

Thank you.

Hi @Michael Cook ,

you could bind multiple public IPs and multiple private IPs to the same NIC of an Azure VM.
Just add another IP config on your NIC.

Just for better understanding:
You wrote "access from the WAN". Does this mean from on-premises network over internet? Or does it mean from a local on-premises network via VPN S2S connection?

Hello @Michael Cook

Thank you for your post.

As per your description, I would like to gather the next observation stated below as well as a couple of pictures:

As it was shown above, I have no PIP(Public IP) but I can either create a new one or use an existing one provisioned before. I move the the toggle bottom to static on the private IP settings so, I can keep the same IP address given via DHCP.

Just a friendly reminder, You might need to permit traffic from Internet to your existing NIC by using NSG(Network security Group).

I hope that was relevant to keep going with your task.

Have a good one.

Cheers,
