I have recently installed Ubuntu 16.04 on my VPS and am trying to get iptables set up, but following the https://help.ubuntu.com/community/Ip...ished_Sessions, when I enter
Code:
iptables -A INPUT -m conntrack -ctstate ESTABLISHED,RELATED -j ACCEPT
I get the following error:
Code:
iptables v1.6.0: -c packet counter not numeric
I've tried but that's not working... Just below that I saw
If the line above doesn't work, you may be on a castrated VPS whose provider has not made available the extension...
so do I need to install an extension for conntrack?
TIA
