How to allow specific ip address to access my webapp deployed in azure?

Question

I have a deployed web app in azure but I want to allow only specific ip address ( or mac address if possible) to access the sites on the web app I deployed on azure. I've been searching for internet for step by step instructions but I really cannot find one. I saw several codes to paste to web.config but I do not know how to do it nor find that file.

What I understand is that I need to setup a network security group found under the settings on my web app but I cannot find it there. I can only see networking. Can someone please provide step by step instructions. TIA

According to your description, we should create an app service Environment(virtual network), in this way, we can add NSG to the virtual network, then we can set inbound rules for this virtual network, in this way, we can control inbound traffic to web app.

We can follow this official article to create app service environment and add NSG to web app.
