I am trying to set specific iptables rules inside a container but so far i have no luck. So far i tried to enter (exec bash) the container and add manually the rules, then, export the running container to a new image.
When i import the image and start the new container the iptable rules are still not there.
How can i have specific iptables rules when the container is created without having to set them automatically?
I am using docker-CE
The image is a custom debian-strech created using debootstrap.
