[LARTC] u32 and iptables do not work together

[Nataniel Klug]

    Hello all,

    I am trying to make a filter into my QoS rules and I founded that 
when I try to use filters u32 and with fwmark they do not work together. 
This is the filter I use, just and example, for u32:

$TC filter add dev $DL parent 1:0 protocol ip prio 1 u32 match ip sport 
22 0xffff flowid 1:10

    This is working fine. Now if I try to mark a package that I want it 
to go to the same class (1:10) it get an error:

$IPT -t mangle -A PREROUTING -s 200.163.208.4 -j MARK --set-mark 10

    Then I tryed to make the filter for this:

$TC filter add dev $DL parent 1:0 protocol ip prio 1 handle 10 fw 
classid 1:10

RETURNS:

[root at ns1 rc.d]# /sbin/tc filter add dev eth3 parent 1:0 protocol ip 
prio 1 handle 10 fw classid 1:10
RTNETLINK answers: Invalid argument
We have an error talking to the kernel
[root at ns1 rc.d]#

    Anyone knows what can I do? My full script (the one that is working 
fine is at the end).

Att,

Nataniel Klug
