[LARTC] About iptables with set --tos option

[makevuy]

Hello,

I want to set the TOS of packets that are entering in my network with 
value 0x00 (or other). For this, I'm using iptables with the next comand:

iptables -t mangle -A FORWARD -i eth1 -s 0/0 -j TOS --set-tos 0x00

The problem ocurrs when my packets have a previous TOS of value 
difference from 0x00, because the comand do the next operation:

OLD_TOS + 0x00 = OLD_TOS

I would want to know if is possible with iptables, change the TOS of the 
packets, althought  the TOS of the packets that are arriving to my 
network is difference from 0x00.

Thanks ad Regards.
