A paket can only have one sourceport, so the match above can not work. You will have to use one filter for each sport! tc filter add dev eth0 parent 1: protocol ip prio 9 u32 \ match ip sport X 0xffff \ flow id 1:30 tc filter add dev eth0 parent 1: protocol ip prio 9 u32 \ match ip sport Y 0xffff \ flow id 1:30 Greetings, Nils
