BINGO! thank you Gui - if i read the old mails, i can even see it
i the transglobal table. if i look into the mesh, it pop's up on
random nodes with random originators. yes: mushroom tripping 8-)

i will try the ebtables approach, but i dont like it.
IMHO it's more elegant to just 'ignore' this mac by the
daemon itself:

To the devs: is this possible?
