Outbound ports to HDInsight management

Hello,

What are the required ports for outbound connection of HDInsight to management IPs and any other needed Azure services when configured with a resource provider connection set to ‘Outbound’?
https://docs.microsoft.com/en-us/azure/hdinsight/hdinsight-restrict-outbound-traffic
I tested with outbound 443,1433,53,80,32526 unsuccessfully.

Thank you in advance,
Alex

Hello @AlexBoata-SAP,

When you say "I tested with outbound 443,1433,53,80,32526 unsuccessfully.", could you please share the below details:

How exactly configured outbound network traffic for Azure HDInsight cluster?

Could you please share the screenshot of the rules configured?

And also, share how exactly have you tested the outbound rules configured?

i used an outbound NSG rule from any IP any port, to service tag ‘Internet’ ports 443,1433,53,80,32526, and without a firewall.
If I change the port to * in the same rule, the deployment succeeds.

The error is "FailedToConnectWithClusterThroughGatewayErrorCode","message":"Unable to connect to cluster management endpoint. Please retry later."

Hello @AlexBoata-SAP,

Thanks for the details.

Note: Configure outbound network traffic for Azure HDInsight clusters using Azure Firewall.

If you are using custom VNet network security group (NSGs) and user-defined routes (UDRs), ensure that your cluster can communicate with HDInsight management services. For additional information see HDInsight management IP addresses.
