1°) As I wrote my rules, each IP address has one handler.
I use this script to display UP and DOWN traffic for the handler in $1:

  #!/bin/sh

  INIF=eth1
  OUTIF=ifb0

  RATEIN=$(tc -s -d class show dev $INIF \
    | egrep -A 5 "class htb 1:$1 " \
    | egrep "rate .+ backlog" \
    | awk '{print $2}')
  
  RATEOUT=$(tc -s -d class show dev $OUTIF \
    | egrep -A 5 "class htb 1:$1 " \
    | egrep "rate .+ backlog" \
    | awk '{print $2}')

  echo $RATEIN
  echo $RATEOUT

I launch it like this:
# get-bw.sh $NNN
Where $NNN is the handler.

When I launch it, I see "0bit" for IN traffic, that means nothing is
trapped.
When I launch it with the handler of the default, I see much traffic.

2°) When varying the "default" allocated bandwidth, I see in my charts
it is the one seen.

Anyway, I solved my problem:
The LAN interface is "eth1" but there is a tunnel "tun0" coupled to it
(I use coova chilli access point).
Just to test, I switched to "tun0" and it suddenly worked.

In all the rules I gave, just replacing "eth1" with "tun0" made it!
(What a dumb I am...)

Thanks for everything.
