Using iptables.
Resetting firewall rules.
Loading kernel modules.
Setting kernel parameters.
Configuring firewall rules.

Ho forse dimenticato qualche modulo mentre ricompilavo il kernel?
Se si mi sapete dire quale?

Modifica:
Ho ricompilato il kernel con l'Aiuto di SirWallace e ora funziona perfettamente!
