After rebooting the server we notice the rules are removed. It’s best to save your configs and restore them after a reboot.
iptables-save > /etc/iptables/rules
iptables-restore < /etc/iptables/rules
flush all rules
iptables -F
flush rules in the input chain
iptables -F INPUT
iptables -L –line-numbers
iptables -D INPUT 3 – delete a line
