title: Whitelist inbound IP address for Azure WebApp?
body: <p>I would like to restrict access to some <em>Web Apps</em> I am developing on Azure through a whitelist of allowed in-bound IP addresses. I have achieved this using <em>Network Security Group</em>, applied to a VM. I can also see how I can achieve this using a <em>App Service Environment</em>, but this is very costly. Is there any way of applying a <em>Network Security Group</em> to a <em>Web App</em>? Or can I add a <em>Network Security Group</em> to a <em>Virtual Network</em>? Or is there another method that I'm overlooking?</p>
  
  <p>Thanks!</p>
