Hello everybody, Hello Stef
Thank You Stef for Your cooperation. Now I will continue to mail in LARTC
maillist.
So the question was why my script was not working.

+---------------+
eth3___ | | ____eth0 (to INTERNET)
10.1.0.0/16 | |
+--------------+

192.168.0.0/24
I completely have rewritten script. Again I try to test at first with one
machine
and if everything is OK, then do for all machines

I use filtering for intermediate classes. As You said, Stef in
"[LARTC] Shaping services and users (2nd time)" message "...You
need a set
of filters attached to the root qdisc so the traffic for the
different IP''s are placed in the IPx class. Then you need a second set
of
filters attached to the IPx classes and redirect all traffic to the different
sub classes."
So I did. Nevertheless the script does not work as it is necessary. Here are the
results: (I cut some results so they are shorter)

As it is seen, all fwmarks in iptables work correctly. When I, e.g., download
from 192.168.0.1, mark 2 is settled correctly, but nevertheless , instead of
going through 1:2 class it goes directly as I planned for not classified traffic
to
other computers. I didn''t put default intentionally.
Well, I will be very grateful to everybody who can point me my fault or suggest
something.
Best regards,
Andrian
