The process of actually setting up the region was very easy. However, I installed NAT Loopback not quite as suggested in the guide since the only available Loopback was named Microsoft KM-TEST Loopback Adaptor and I configured everything and followed the instructions. Everything would appear to be set up correctly with the settings asking the Loopback to automatically find the IP address. Unfortunately NAT Loopback cannot find the IP address on my machine and just keeps trying to find it without success making it impossible for me to resolve. Has anyone come across this before I wonder?
