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

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.
