Доброго времени суток.

Есть сервер Linux citadel.itc 2.6.18-ovz-smp-alt14 #1 SMP Wed May 2
15:41:34 MSD 2007 x86_64 GNU/Linux

В нём работает несколько контейнеров, которые длжны использовать NAT.
Соответственные настройки
вписаны в конфиги:
ovpn.itc - IPTABLES="iptable_filter iptable_nat "
proxy.itc - IPTABLES="iptable_filter iptable_nat "

При входе на proxy.itc пробуем:

[root@proxy /]# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
[root@proxy /]# iptables -t nat -L
FATAL: Could not load /lib/modules/2.6.18-ovz-smp-alt14/modules.dep: No
such file or directory
iptables v1.3.7: can't initialize iptables table `nat': Incompatible
with this kernel
Perhaps iptables or your kernel needs to be upgraded.

При останове этих контейнеров получаю Oops (тут, тот самый proxy.itc):

Собственно, как исправить причину такого Oops?
