Activate ip forwarding - persistent - ubuntu core

I'm trying to activate ip forwarding at boot-time on my ubuntu core image. I can run the command:



sudo sysctl -w net.ipv4.ip_forward=1


It works. Then I reboot the machine, the forwarding is gone.
On ubuntu server I can update the file /etc/sysctl.conf .



This file is "read only" in ubuntu-core.



What is the "prefered" way to add ip forwarding in ubuntu core?

          If you have superuser permissions you can edit any file with any permissions. Open /etc/sysctl.conf with your favourite editor (vi, nano etc) find string #net.ipv4.ip_forward=1, remove the leading # symbol, save the changes. And run sudo sysctl -p.



          Also, you can reboot your machine to make sure the changes are in place.

                    Pour les articles homonymes, voir Ellipse. L'ellipse est le lieu des points dont la somme des distances à deux points fixes, dits foyers, est constante. Section du cône ou projection du cercle. En géométrie, une ellipse est une courbe plane fermée obtenue par l’intersection d’un cône de révolution avec un plan, à condition que celui-ci coupe l'axe de rotation du cône ou du cylindre : c'est une conique d'excentricité strictement comprise entre 0 et 1. On peut également la définir comme le lieu des points dont la somme des distances à deux points fixes, dits foyers, est constante (sa construction par la méthode du jardinier est très simple). Dans la vie courante, l’ellipse est la forme qu'on perçoit en regardant un cercle en perspective, ou la figure formée par l’ombre d'un disque sur une surface plane. On retrouve aussi, en première approximation [ 1 ] , des ellipses dans les trajectoires des corps célestes (planètes, comètes ou satellites arti...

                    Quarter-circle Tiles
