How to Assign Static Private IP to NAT Gateway

How do I Assign Static Private IP to NAT Gateway?

It keeps on asking for a public IP and I see no way to assign just a private IP here. Do you mean assign a public/private IP pair? Please share documentation or steps to achieve this.

The private IP configuration is on the Subnet tab by specifying the Virtual network and Subnet:

Hi @Anchal Singh,

Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

In the Nat Gateway, we can assign either a public IP address or IP prefixes, but not a private IP.

Refer this doc:
