Since the other question about this (Multiple network interfaces on a single NIC in Windows) only asks about different routing, I'm going to ask this again:
Is there any way to create multiple virtual connections, each with its own MAC address, from a single network adapter on a Windows machine?
I know Linux supports this. I basically need to simulate to the network, that one computer is actually two computers, each with different MAC and therefore IP address.
Previously I have done this with another USB ethernet adapter, but this is no longer the option.
Note that this is NOT a wireless network, so Virtual Wifi adapters built-in Windows won't help for this.
