I have a private switch created on a Hyper V host
I have a VM with 2 vNICs installed, one is connected to the interal network with all my live environment, the other is attached to the private network. The VM has RRAS installed and running NAT to allow VMs on the private network to access the internet through this.
My question is:
The private VMs can access the internet fine. But they can also ping the servers on the internal live network.
Clients and servers on the internal live network can NOT ping the private VMs.
Is this what I want in terms of having the test environment cut off from the live environment? I'd like to be able to bring up a test DC on the private network but i'm concerned it is still linked enough to the live environment to cause issues
