[LARTC] Traffic goes not through filters.

[Erestor Elensar <erestor.elensar@gmail.com>]

Hi,

I think i have made an error with my filters but i can't find it.
We have a site to site tunnel and want to separate the traffic in two
queues, http and business.

I'm now filtering on protocol 8080 prio 2 and ip range prio 1.
As i read the manual i've seen that the filters are executed by prio
means that all goes trough the buisiness queue because all traffic is
for the same ip range.
And indeed i see only traffic in 1:30 and not in 1:20


Can someone tell me how to set this up ?

Thanks.


My code:
