first i use imq patch for kernel 2.6.9 and htb for some traffic management and i want to redirect this kind of trafic to imq1 or imq0 and then to came with some htb rules. just this ... #iptables -t mangle -A PREROUTING -m tos --tos 0x15 -j IMQ --todev 0 iptables v1.2.11: Bad TOS value `0x15' Try `iptables -h' or 'iptables --help' for more information. #iptables -t mangle -A PREROUTING -m tos --tos 15 -j IMQ --todev 0 iptables v1.2.11: Bad TOS value `15' Try `iptables -h' or 'iptables --help' for more information. > >Please post it also to the list so more people can help ;).
