Enable a Service Fabric Service to send PING to an external host (C#)

Question

I have a method in a Service Fabric Stateless Service (not an API) that sends a PING request to an external host. It works on my Local Service Fabric Cluster, but not on the actual cluster on Azure.

I RDP'd to the cluster and pinged hosts, all of them resulted to "Request timed out".

Anyone tried this before? I'm playing around the cluster's Firewall.

ICMP is blocked inside Azure. You can use PSPing to check connectivity though.

More info here .

Because the ICMP protocol is not permitted through the Azure load balancer, you will notice that you are unable to ping an Azure VM from the internet, and from within the Azure VM, you are unable to ping internet locations.
