I have trouble integrating an ACS Engine Cluster with my existing VNET in Azure. Below are the steps to reproduce my issue:

1. Create an ACS Engine Cluster with default configuration. It creates its own VNET(let's say ACS_VNET)
2. Create a new VNET(VNET2) with a VM and do a VNET Peering to ACS_VNET.
3. Create a sample service with Azure Private Load Balancer and try to access its private IP from the above VM in VNET2. It does not work. Also tried with Private IP of the pod and with a NodePort with no luck.

Followed this article to create the cluster: https://dzone.com/articles/create-custom-azure-kubernetes-clusters-with-acs-e

Above steps works for an AKS Cluster in Azure.
