title: iptables: how to delete postrouting rule?
body: <p>I would like to delete POSTROUTING rule below,</p>
  
  <pre><code>[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         
  </code></pre>
  
  <p>then I typed below,</p>
  
  <pre><code>[root@hostname ~]# iptables -D POSTROUTING 1
  iptables: No chain/target/match by that name
  </code></pre>
  
  <p>Is there anything wrong?</p>
