iptables v1.3.5: can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
This solution applies to all other iptables modules/problems for OpenVZ, you'll just need to add them to both lists/lines below if you have modules other than what I have below.
The modules need to be enabled in both iptables and the OpenVZ hostnode itself and then the containers which need it must be restarted.

OpenVZ iptables v1.3.5: can't initialize iptables table `nat': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. Solution
This error is annoying, in a Virtuozzo KB entry about this ip tables nat problem they say the kernel needs to be ugpraded:
Symptoms
The node runs 2.6.18-x kernel older than 2.6.18-028stab053.10.
NAT module does not work in container, you get "can't initialize iptables table 'nat'" error:

Openvz Enable Most Common iptables modules
The default options for iptables are very basic. Here is what you need to do in order to enable them in OpenVZ.
1.) Add the modules to iptables and restart iptables:
vi /etc/sysconfig/iptables-config
Edit the line as so:
IPTABLES_MODULES="ipt_REJECT ipt_tos ipt_TOS ipt_LOG ip_conntrack ipt_limit ipt_multiport iptable_filter iptable_mangle ipt_TCPMSS ipt_tcpmss ipt_ttl ipt_length ipt_state iptable_nat ip_nat_ftp"
