[Cooker] iptables don't work ?

[José Luiz Barci Neves]

in mandrake 8.0b my iptables -L show-me:

iptables v1.2: can't initialize iptables table 'filter': iptables who? (do
you nedd insmod?) 
Perhaps iptables or your kernel needs to be upgraded.

My kernel is 2.4.2-3mdk

i have tried insmod ip_conntrack but anything changes.

thanks.
