(Solution) Reload iptables on every boot

Hi, To be able to load your iptables ruled every time your Linux system is restarted just follow these commands.$ sudo iptables-save /etc/firewall.conf Open /etc/network/if-up.d/iptables and add: Provide executable permission:$ sudo chmod +x /etc/network/if-up.d/iptable Now, your iptable rules will be loaded every time your Linux box is booted. If you need to modify your rules just execute:$ sudo iptables-save /etc/firewall.conf Regards,Rubén
