iptables and CONNMARK on ubuntu 14.04

Question

How to enable connmark in netfilter in ubuntu 14. I see this post but I don't find the good module in Ubuntu 14.04.

I use connmark for multiwan. My configuration run perfectly in debian 8. But no connmark in ubuntu 14.

Answer 1

To enable the module on the kernel you can do:

modprobe nf_conntrack_ipv4

or

modprobe ip_conntrack

And to use conntrack you can install it like this(if using ubuntu):

apt-get install conntrack
