Assuming your service accounts are correctly linked to the instances, this rule looks correct to me. Make sure you are pinging the internal IP address for the BE instance once you have SSH’d onto the FE instance as you are within the VPC at that point!
I have the same setup. However, I do not understand why only the internal IP address is pingable , and not the external IP address ? Shouldn’t the ping goes thru external IP address, rather than Internal IP?
I have the same question!
Ah yeah, you are right Robin.. We should actually ping the internal IP addresses. I was also facing the same issue posted by Jorge
