------- Additional Comments From blin@gmx.net 2007-08-05 10:31 ------- This is interesting. Do you get the selection option in wine?
As to your suggestions.. The windows way of determining the "primary nic", as you called it is by keeping a stack of interfaces/addresses, and always returning the top address. We didn't really have any good ideas to really implement that in Wine.
However, the windows way of handling this means that for most use cases, other games work fine on Windows, so it's unlikely that anyone will bother fixing it. Dylan's patch cheats by giving out a list of interfaces in order of the user's preference, which is as close as we can get to Windows behavior right now.
Thus, unless there's something else going wrong with IL-2, I think it's still a dup of bug 7929
