FreedomBox on LXC

Hi, for information,
I use put a Freedombox inside LXC container and made it only accessible from a OpenVPN server inside the container too.
Here, you will find more explanation on how to setup Freedom Box in a container :

I used the LXC MACVLAN option so that my container is directly accessible on the local network and its IP adress is provided by the Box of my ISP.

Coming to firewall issues opened by NickA FreedomBox on LXC - #5 by NickA

I understood that there is a lack of compatibility between the Firewalld use by the Freedom Box and LXC. So I removed it and choose to build the firewall function using IPTables.

#Remove firewalld

sudo service firewalld stop
sudo apt-get purge firewalld
# install Iptables persistent
apt-get install iptables-persistent

After that I used one script to set IPtables rules :
cd ~
mkdir config-iptables
cd config-iptables
nano iptable-config.sh # the script is given on next post
chown 700 iptable-config.sh
