When stepping through shared files, I see (in many cases) files, that lie on a host with IP 192.168.x.x

These are obviously unroutable hosts because they're in a private class C-Network, so a download from such a source could never succeed!

Am I wrong with this? Is a download possible?

And: why are people sharing files, if they don't want uploads?
Better do not share any files :-(

So far, scotti
