:INPUT DROP [0:0]

:OUTPUT DROP [0:0]
:RH-Firewall-1-INPUT - [0:0]
#上面四条内容定义了内建的INPUT、FORWAARD、ACCEPT链,还创建了一个名为RH-Firewall-1-INPUT 的新链
-A INPUT -j RH-Firewall-1-INPUT
#上面这条规则将添加到INPUT链上,所有发往INPUT链上的数据包将跳转到RH-Firewall-1 链上。
-A FORWARD -j RH-Firewall-1-INPUT
#上面这条规则将添加到FORWARD链上,所有发往FORWARD链上的数据包将跳转到RH-Firewall-1 链上。
-A OUTPUT -j RH-Firewall-1-INPUT
#上面这条规则将添加到OUTPUT链上,所有发往OUTPUT链上的数据包将跳转到RH-Firewall-1 链上。
-A RH-Firewall-1-INPUT -i lo -j ACCEPT
#上面这条规则将被添加到RH-Firewall-1-input链,它可以匹配所有的数据包,其中流入接口(-i)是一个环路接口(lo),匹配这条规则的数据包将全部通过(ACCEPT),不会再使用别的规则来和它们进行比较。
-A RH-Firewall-1-INPUT -p icmp --icmp-type any -j ACCEPT
#上面这条规则是允许所有的icmp包,-p后是协议如:icmp、tcp、udp,端口是在-p后面--sport源端口,--dport目的端口,-j 指定数据包发送目的地址后的动作如:ACCEPT、DROP、QUEUE等。
-A RH-Firewall-1-INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
#-m state --state ESTABLISHED,RELATED这个条件表示所有处于ESTABLISHED或者RELATED状态的包,策略都是接受的。
-A RH-Firewall-1-INPUT -m state --state NEW
#-A RH-Firewall-1-INPUT -m state --state NEW这个条件是当connection的状态为初始连接(NEW)时候的策略。
其他策略见注释说明。
