iptables help. Error iptables v1.4.7: can't initialize iptables table `nat'

Cam · July 2017

Hello,

I am getting an error whenever I am trying to add any iptable rules. For example if I runiptables -t nat -L
I get response,
iptables v1.4.7: can't initialize iptables table nat': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded.

I have a fresh install of CentOS 6.8 with SolusVM successfully installed and booted into the OpenVZ kernel 2.6.32-042stab123.8.

lsmod gives,
https://pastebin.com/YeTbGReK

I have tried grep -R "options nf_conntrack ip_conntrack_disable_ve0=0" /etc/modprobe.d/ still without any luck of it working.

Thanks,
Cam

you scare us if you cannot even google something like this since it isn't that hard and usually with you being a "provider" with the provider tag and running a web hosting business you are at least expected to have some knowledge at least on how to fix issues like this which leads us to this meme instead lol:

you also have already asked this already before it appears:

Thank you for showing how kind you are to LET. I am reaching out on here because I have looked up and down trying many things to resolve this. I am not the type of person who usually reaches out for help on issues like this but this is something that is actually giving me a tough time.

Don't tell me that I didn't try to google this. Because you really don't know.

Thanks,
Cam

this webpage could help https://serverfault.com/questions/593263/iptables-nat-does-not-exist, and shouldn't you update to CentOS 6.9

Hello,

Thanks for that. I did look at that page and tried the answer with no luck.

I run grep -R "options nf_conntrack ip_conntrack_disable_ve0=0" /etc/modprobe.d/ and reboot and still get the same error when adding a rule.

Typo on my part, it is 6.9.

Thanks,
Cam

you also did the part of changing that setting to 1 in the file you hopefully found and just omitted that part here? just so to say... grepping for a file won't change anything after all ;-)

Grep nf_conntrack /boot/config*

You need to set iptable_nat in vz.conf on the host node. https://forum.openvz.org/index.php?t=msg&goto=42693&;
