interface? I tried hunting all-around but all I found is loopback. I would like the other conclude from the wire acknowledges this as two interface, so loopback won't do it. Hypervisors like VMWare have an option to do accurately this (VM and host are recognized as two units on router's arp desk), but in my scenario utilizing a Rungrong VM is pretty much overkill.
