iptables v Redhatu

[Daniel Klicka]

Dobry den,
mam RedHat 7.0CZ s upgradovanymi iptables a jadrem primo z distribuce
Redhatu 7.1.
Potreboval bych nastavit tato jednoducha pravidla pro iptables:
iptables -P INPUT ACCEPT
iptables -A INPUT -p tcp -m multiport --destination-port 22,80 -j ACCEPT
iptables -A INPUT -j REJECT

pokud je zadam jako prikazy z konzole, vse funguje jak ma.
Ale pokud presne tohle, s vynechanim prikazu iptables, ulozim do souboru
/etc/sysconfig/iptables a spustim iptables pomoci
/etc/init.d/iptables start
skonci to s chybovou hlaskou:
ptables-restore v1.2.2: can't initialize iptables table `': Table does not
exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

Nevite, kde delam chybu?
Dekuji.
