Ok, that's quite like a direct link I guess. At my old Company (a graphical Business) we've had - unfortunatley - a lot of problems with Macs because of the Spanning Tree Protocol. Newer G3 and G4 have a faulty implementation in the networking hardware and behave strange with equipment that utilizes this. But I don't think, your constellation works like that.
