Since I wrote that part, I can tell for sure it doesn't support automatic 
detection. But of course you can implement that if you want. You can search for

- the GUID of the adapter (don't know if that helps you much)
- the name of the adapter (could be difficult, too, as that name can be changed 
by the user)
- have some automatic fallback, but that would mean with a real and a virtual 
LAN, it could go wrong
- rely on the company part of the adapter's MAC (that should be the same for 
all your virtual LANs)

As you can see, all approaches have a downside, which is why there is no 
automatic detection, yet. You could also write the index into a configuration 
file, which is parsed when the lwIP process is started.

After all, the win32 port was started as a development project. I don't know if 
it is safe to be used in a production environment (if that's what you are 
looking for).
