iptables string ни в каком варианте не работает.

Пробую забить правило:

iptables -A FORWARD -m string --string «X-Forwarded-For» --algo kmp --to 65535 -j DROP

Захожу на одноименную страничку в педевикии.

Пробую --algo bm, результат тот же.

Что пробовал:


    0     0 DROP       tcp  --  *      *       0.0.0.0/0            0.0.0.0/0           STRING match "Forwarded" ALGO name kmp TO 65535 
    0     0 DROP       tcp  --  *      *       0.0.0.0/0            0.0.0.0/0           STRING match "Forwarded" ALGO name bm TO 65535

    0     0 DROP       tcp  --  *      *       0.0.0.0/0            0.0.0.0/0           STRING match "X-Forwarded-For" ALGO name kmp TO 65535 
    0     0 ACCEPT     tcp  --  *      *

  13M 1113M VYATTA_POST_FW_FWD_HOOK  all  --  *      *       0.0.0.0/0            0.0.0.0/0           
    0     0 DROP       all  --  *      *       0.0.0.0/0            0.0.0.0/0           STRING match "X-Forwarded-For" ALGO name kmp TO 65535 
    0     0 DROP       all  --  *      *       0.0.0.0/0            0.0.0.0/0           STRING match "X-Forwarded-For" ALGO name bm TO 65535

Почему по нулям? Пробовал также INPUT и OUTPUT резать, результат нулевой.

o_O.

Ну вот так не работает, захожу на http://en.wikipedia.org/wiki/X-Forwarded-For , ни одного пакета не фиксируется.
