CentOS - Dec 2012 - iptables 1.4 and kernel 2.6 CONFIG_IP_NF_MATCH_STATE

Hi,

   I have a VPS running Centos 6.2 and trying to run this iptables rule:

   [root at myserver ~]# iptables -A INPUT -i venet0 -m state --state 
ESTABLISHED -j ACCEPT

iptables: No chain/target/match by that name.

   Narrowing down the issue it seems there is no IP_CONNTRACK support 
but now it's called NF_CONNTRACK. However following this link:

   http://www.spinics.net/lists/netfilter/msg33535.html

   I have found that I don't have CONFIG_IP_NF_MATCH_STATE support.

   Unfortunately this virtuozzo VPS is not using modules:

   [root at vrtl13369 ~]# lsmod
Module                  Size  Used by

   How can I enable that CONFIG_IP_NF_MATCH_STATE support in my kernel? 
I prefer to stick to the kernels provided by the repos and not recompile 
my own kernel.

   Regards,

   Miguel

Sounds like your are not running the standard kernel, but something 
provided by your VPS provider. If that is indeed the case you have to ask 
them.
