Hi Simon,
Thank you very much for the informative reponse. I dont know until now about the stability of the win32 port of lwIP. Since I am using it now and found to be useful and working according to my design, I will continue with it. Anyways, I will take a look on some of your approaches on how to deal with the lwip stack network adapter. I think this one is much better:
[..] 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.
Again, thank you very much.
Best regards,
Emmanuel

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).
