> Post your script and maybe we can help. Ok thank you - a script says more than thousand words I guess - but I only kept the essential parts: # here we go: tc qdisc add dev eth2 root handle 1: htb default 1000 tc class add dev eth2 parent 1: classid 1:100 htb rate 10400kbit ceil 10400kbit tc class add dev eth2 parent 1:100 classid 1:1000 htb rate 128kbit ceil 10400kbit prio 3 quantum 2000 tc class add dev eth2 parent 1:100 classid 1:2000 htb rate 512kbit ceil 10400kbit prio 1 quantum 20000 tc class add dev eth2 parent 1:100 classid 1:1021 htb rate 10kbit ceil 512kbit prio 3 quantum 2000 tc class add dev eth2 parent 1:100 classid 1:1022 htb rate 10kbit ceil 512kbit prio 3 quantum 2000 tc class add dev eth2 parent 1:100 classid 1:1023 htb rate 10kbit ceil 512kbit prio 3 quantum 2000 ... # this goes on for a couple of hundred classes ... # test class which I am trying to give all the traffic not belonging to other classes tc class add dev eth2 parent 1:100 classid 1:5000 htb rate 10kbit ceil 256kbit prio 3 quantum 2000 # now the filters: tc filter add dev eth2 pref 1 protocol ip parent 1: u32 match ip dst aaa.bbb.ccc.ddd/32 flowid 1:2000 tc filter add dev eth2 pref 1 protocol ip parent 1: u32 match ip src aaa.bbb.ccc.ddd/32 flowid 0: tc filter add dev eth2 pref 100 protocol ip parent 1: u32 match ip dst aaa.bbb.ccc.ddd/32 flowid 1:1021 tc filter add dev eth2 pref 100 protocol ip parent 1: u32 match ip dst aaa.bbb.ccc.ddd/32 flowid 1:1022 tc filter add dev eth2 pref 100 protocol ip parent 1: u32 match ip dst aaa.bbb.ccc.ddd/32 flowid 1:1023 ... # this goes on for all the classes ... # now my test filter which should prevent all other traffic going to default tc filter add dev eth2 pref 200 protocol all parent 1: u32 match ip dst 0.0.0.0/0 flowid 1:5000 ----------------------------- With "tc -d -s class show dev eth2" I see traffic flowing through the classes nicely but I see just about 20bps in 1:5000 and about 30000bps in default (1:1000). Anybody can tell me why? What kind of traffic doesn't get matched by "dst 0.0.0.0/0" and "protocol all"? And yes - these are all public IPs. thanks!
