title: Azure Data Factory can't access HDInsight cluster in IP restricted VNet
body: <p>I have a HDInsight Hadoop cluster (Linux, deployed separately) on Azure VNet (restricting client IPs using NSG). </p>
  
  <p>Azure SQL firewall has an option called "Allow access to Azure services", which allows Data Factory to access Azure SQL. </p>
  
  <p>In VNet there is no such option, you have to either specify IP addresses range or set a tag (Internet, Virtual Network, AzureLoadBalancer). I thought AzureLoadBalancer will solve the issue, but no - HDInsight is still hidden from Azure Data Factory.</p>
  
  <p>I tried to find Data Factory port ranges, unsuccessfully. </p>
  
  <p>Is there a way to access secured HDInsight Linux cluster from Azure Data Factory?</p>
