yes.blew my scripts.

when I use iptable -L -v -n -t mangle,I have below infor
PREROUTING chain:
 pkts bytes target     prot opt in     out     source               destination
 305 40889  MARK       tcp  --  eth0   *       0.0.0.0/0            0.0.0.0/0          tcp dpt:80 MARK set 0x3
FORWARD chain:
 pkts bytes target     prot opt in     out     source               destination
 0     0    MARK       tcp  --  *      eth0    0.0.0.0/0            0.0.0.0/0          tcp dpt:80 MARK set 0x3

why not stream through ForWard chain ? beacause this all traffic into 20:20(default class)?
