As a workaround I created a native bridge, with just my physical interface
as a device, and then I reconfigured the xen domU's to bind to that bridge,
instead of the xenbr0, and it works like a charm, but I doubt that it is the
way it should work. That works for me, and I am fine with that, but if
anybody has a hint on how to do it with using xenbr0, please let me know.
kind regards
Sebastian
