How enable kernel iptables options?

Hi at all,

I want enable the iptables features in my custom Angstrom filesystem
and kernel, I have followed the nexts steps to add this features to my
kernel:

Networking options —>
[] Network packet filtering framework (Netfilter) —>
Core Netfilter Configuration —>
[
] Netfilter connection tracking support
-- Netfilter Xtables support (required for ip_tables)
[
] “conntrack” connection tracking match support
[] “state” match support
IP: Netfilter Configuration —>
[
] IPv4 connection tracking support (required for NAT)
[] IP tables support (required for filtering/masq/NAT)
[
] Packet filtering

But I get this error when my beaglebone is booted:

[ 5.059593] x_tables: disagrees about version of symbol nf_register_hooks
[ 5.066763] x_tables: Unknown symbol nf_register_hooks (err -22)

[ 5.140496] x_tables: disagrees about version of symbol
unregister_pernet_subsys
[ 5.148330] x_tables: Unknown symbol unregister_pernet_subsys (err -22)

I know that there is some error with these symbols, anybody know how
can I solve this error?
I have tried to test iptables features and It’s works fine, but I’m
not sure if it’s stable.

Thank you.

After update your kernel ,
#export INSTALL_MOD_PATH=/tmp
#make modules_install
#cd /tmp
#tar cvf lib.tar lib
copy lib.tar to board
#tar cvf lib.tar -C /
reboot

I had used OpenEmbedbed to make my kernel and modules to install into my filesystem.

These steps that you said me is for install these modules,is it rigth?

I did that, but I continuous get this error.
