Currently I've two VirtualMachines in ARM which are connected to an External Load Balancer on port TCP/80 succesfully.
Additionally I want to add an Internal Load Balancer and point this ILB to the same two VirtualMachines with the same port (TCP/80).
Adding the Load Balancing Rule for the ILB results in the following error, it seems to me that two load balancing rules (internal and external) pointing to the same VirtualMachines and Port (TCP/80) is not possible.
Can anyone confirm this, or do you think this should be possible?
