@yull1860 Thanks for opening this Issue. We have a task to enhance the documentation on configuration with VNET: #97

In the meantime, @ygrik / @azaslonov - could you please assist?

@yull1860 - apologies for delay in the response. We have added an explanation in the Azure documentation: https://docs.microsoft.com/en-us/azure/api-management/api-management-howto-developer-portal#what-do-i-need-to-configure-for-the-new-portal-to-work-in-my-api-management-service-in-vnet

Other articles also describe allowing the connectivity on new developer portal's endpoint.
