First question ist there any way to check which ip's go trough default > HTB class ? It would be possible to mirror traffic reaching the default class to an ifb like this: tc filter add dev eth0 parent 1:defaultclass protocol ip priority 10 u32 \ match u32 0 0 flowid 1: action mirred egress mirror dev ifb0 Then just run a tcpdump on ifb0.
