#!/bin/bash
/sbin/ip6tables -A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT;
/sbin/ip6tables -A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT;
/sbin/iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT;
/etc/rc.d/init.d/iptables save;
/etc/rc.d/init.d/ip6tables save;
service iptables restart ;
service ip6tables restart ;

保存之后 /etc/sysconfig/  出现iptable.save....

必须在reject之前 需要选择顺序

/sbin/ip6tables -I INPUT 4 -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT;
/sbin/ip6tables -I INPUT 5 -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT;
/sbin/iptables -I INPUT 1 -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT;
/etc/rc.d/init.d/iptables save;
/etc/rc.d/init.d/ip6tables save;
