Si vous avez le message d'erreur suivant quand vous voulez utiliser iptables

<code>libkmod: ERROR ../libkmod/libkmod.c:554 kmod_search_moddep: could not open moddep file '/lib/modules/3.6.11+/modules.dep.bin'
iptables v1.4.14: can't initialize iptables table `filter': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.</code>
