iptables: how to delete postrouting rule?

Question

I would like to delete POSTROUTING rule below,

[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

then I typed below,

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

Is there anything wrong?

Try adding the table name explicitly:

iptables -t nat -D POSTROUTING 1

"is necessary" -- did you mean "is not necessary" ? Or did this fix your problem? – sarnold Nov 23 '11 at 08:39

Oh finally I found what I was looking for so long, thanks so much for your answer! Was messing around with my iptables configuration for hours and I always missed the -t nat part when trying to remove a very buggy rule. God bless you! +++ – beta Sep 17 '12 at 09:16

This didn't work for myself Ubuntu 13.04 (maybe from my own doings) but ```iptables -t nat -F``` did – davidcollom Oct 14 '13 at 16:19
@davidcollom, thanks, I marked your comment up with the hopes it'll be useful to someone else in the future. – sarnold Oct 15 '13 at 22:23
`service iptables status` doesn't show `nat` in its output. Is it possible to print it out? – Incerteza Mar 16 '14 at 06:18
@AlexanderSupertramp - `iptables -t nat -L` should show you the nat table – davidcollom Sep 08 '14 at 15:31
