删除特定的iptables规则

我有以下的iptable规则，并需要帮助删除它，如果可能的话？

iptables -t nat -I PREROUTING -p tcp --dport 12348 -j DNAT --to-destination 192.168.0.5:12348 iptables -t nat -I PREROUTING -p tcp --dport 7778 -j DNAT --to-destination 192.168.0.5:7778

我知道-D代表删除规则，但我无法弄清楚在我的命令我的意思是把它放在哪里，

提前欢呼

更新了==>

iptables的输出-L -t nat：

使用iptables -F PREROUNTING可以删除链式PREROUNTING的所有规则。

使用iptables -D PREROUTING 1你可以从链PREROUTING中删除一个单独的第一条规则。所以要删除以上两条规则，你必须使用相同的命令两次。

使用iptables -t nat -D PREROUTING -p tcp -dport 12348 -j DNAT -to-destination 192.168.0.5:12348和iptables -t nat -D PREROUTING -p tcp –dport 7778 -j DNAT –to-目的地192.168.0.5:7778删除这两个特定的规则。

用-D替换-I。
