Hi, recently Martin explained, how to avoid these "tc filter" lines in our scripts. unfortunatly it doesn't work with my setup. i add a "dummy" tc filter - line: tc filter add dev imq1 parent 10:0 protocol ip prio 1 handle 1 fw classid 10:10 which of course works, but i have no fwmark "1", but as i thought it's just a "dummy" -line for tc filter to work, i gues/think that's ok. further i just set marks with iptables, and generate the right qdiscs/classes for them: ack=0x00100010 # for classid 10:10 high=0x00100011 # 10:11 norm=0x00100012 # and so low=0x00100013 # on but it doesn't work :( am i missing something?! i gues it's the "not-really-dummy" tc-filter line ?! :) thank you very much Tobias
