I want an application that models a network adapter.

I want the virtual plugs will have the ability to talk to one another. For instance, basically i've 2 virtual adapter (on a single computer): interface1-1.1.1.1 and interface2-1.1.1.2. I would like the packets that'll be send through interface1 is going to be received in interface2.

I've being an choice to install VMWare server, however i prefer some thing specific. anybody have ideas?

Are you currently running Home windows? Home windows includes a built-in loopback network adapter that you could install and manage from inside your network configurations. You could have multiple cases of them plus they work/manage as being a physical network adapter.
