Identify eDonkey Packets

["Martin Paulat" <martin@xxxxxxxxxxxxx>]

Hi,

I would like to mark any edonkey packets for traffic shaping. i tried to
identify those packets by sourceport/destport, but many clients use
different ports (i.e. 80).

i read that the first data byte identifies the edonkey packet, but how can i
filter it out?

any suggestions?

many thanks,
    martin
