sysctl and iptables rule after reboot

Hi,

I installed the VPN Manager, configured a profile from my VPN provider, and it works great. Now I enabled ipforwarding with

Code

sysctl -w net.ipv4.ip_forward=1

and added iptable rules

Code

~ # iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
~ # iptables -t nat -A POSTROUTING -o tun0 -j MASQUERADE

it works great, now i can access the internet throug my libreelec-device over my vpn provider

But: After Reboot, the ipforwarding is disabled and the iptable rules are lost.

How can I make them persistent? I can't apt-get install iptable-persistent, and i cant create a /etc/sysctl.conf file.

Thanks!

You can use autostart.sh or systemd.
