Azure WebApp的白名单入站IP地址？

Question

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

Thanks!

You can restrict IP addresses in the web.config using the ipSecurity element like so:

<system.webServer>
  <security>
     <ipSecurity allowUnlisted="false">
       <add ipAddress="XXX.XXX.XXX.XXX" allowed="true" />
     </ipSecurity>
  </security>
</system.webServer>
