OpenVZ VPS: Module ip_tables not found. iptables v1.4.8: can't initialize iptables

[Fli]

There is an error on one OpenVZ based VPS:

i did command "iptables -t nat -nvL" and result:


WARNING: Deprecated config file /etc/modprobe.conf, all config files belong into /etc/modprobe.d/.FATAL: Module ip_tables not found.
iptables v1.4.8: can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

When doing this same command on another VPS, it worked without error.

I made it working this way:

I checked OpenVZ VPS host server and it appears like the iptables nat module is there:

# lsmod | grep nat

iptable_nat 6302 0
nf_nat 23213 4 ipt_MASQUERADE,ipt_REDIRECT,vzrst,iptable_nat
nf_conntrack_ipv4 9946 100 iptable_nat,nf_nat
nf_conntrack 80313 8 xt_helper,xt_connlimit,xt_state,vzrst,vzcpt,iptabl e_nat,nf_nat,nf_conntrack_ipv4
ip_tables 18119 3 iptable_mangle,iptable_nat,iptable_filter

if not, maybe doing "modprobe iptable_nat"

then edit VPS config file from host server: vi /etc/vz/conf/VMID.conf

and comment out this line:

NETFILTER="stateless"

to become:

## NETFILTER="stateless"

then saved file and rebooted VPS:

vzctl restart VMID

(one may also try this instead: vzctl set VMID --netfilter full --save)

And then iptables -t nat -nvL started working with result:
