iptables:如何删除rule规则？

Question

我想删除下面的POSTROUTING规则，

[root@hostname ~]# service iptables status
Table: nat
Chain PREROUTING (policy ACCEPT)
num  target     prot opt source               destination         

Chain POSTROUTING (policy ACCEPT)
num  target     prot opt source               destination         
1    MASQUERADE  all  --  192.168.1.0/24       0.0.0.0/0           

Chain OUTPUT (policy ACCEPT)
num  target     prot opt source               destination         

然后我在下面输入，

[root@hostname ~]# iptables -D POSTROUTING 1
iptables: No chain/target/match by that name

有什么问题吗？

Answer 1

尝试显式添加表名：

iptables -t nat -D POSTROUTING 1
