>>I can see the counter works in iptables, but in the htb, it doesn't go to
the right class
Please write what commands do you use to see "the counter" and what counter
do you mean? I think counter for ip packets isn't it?

You can try to see my problem in LARTC archive: "HTB 3.13 please help".

 In my opinion you have bad configured packet marking.
See my configuration of packet marking. I included it with archive posts in
"HTB 3.13 please help"
