Installing NCPA for nagios, I found these instructions
iptables -I INPUT -p tcp --destination-port 5693 -j ACCEPT apt-get install -y iptables-persistent Answer yes to saving existing rules
Of course, I cannot save ALL ruleset. Because I am using failban and actually my iptables ruleset is veeeery big.
I'd like to persist only
iptables -I INPUT -p tcp --destination-port 5693 -j ACCEPT
Is it possible?
Is still really needed to use iptables-persistent to keep firewall rules? I have a doubt because I am using port 80 and a few others without any problems after system reboots...
So, When I reboot the system, will normally iptables reset all rules? If yes Why ? If no .. wel...
