snad po 60ty krat;) iptables restore pri boote elegantne
apt-get install iptables-persistent
On install, it should save your current iptables config. Otherwise you can save them to these files (depending on v4 or v6) and iptables-persistent will load them on boot 🙂
iptables-save > /etc/iptables/rules.v4
ip6tables-save > /etc/iptables/rules.v6
