Hello Tobias! > 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 As far as I understood Devik, this should look like: tc filter add dev imq1 parent 10:0 protocol ip prio 1 handle 1 fw So no classid term (makes sense, since the classid term is incorporated into the --mark statement).
