никак не могу заставить iptables работать.
ядро 2.4.35.2. что может быть не так?

[root@localhost /root]# iptables -L
iptables v1.3.8: can't initialize iptables table `filter': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
[root@localhost /root]# lsmod
