What I observed, is the client allocated ports DEST/DEST+1, then the
server allocated SRC/SRC+1, but failed because SRC+1 == DEST.
(that's how I triggered the bug in net_OpenDgram fixed in
So, because of this previous bug, I didn't have a chance to check what's
really happening in this case.
But I can confirm that this happened server side, because the client
previously allocated DEST/DEST+1.
