Deleting a rule from a DNAT chain

Deleting a rule from a DNAT chain

[Eugene Joubert]

Hi,

I'm a little rusty. I need to delete a rule from a NAT user defined
chain. The chain is called PortForwarding_3191. I know to use -D but my
syntax is up to crap.
I did not create the rule myself as it was created by some sort of
webinterface.
Any help on the syntax will be appreciated.

Regards,
Eugene

iptables -t nat -D PortForwarding_3191 <rule number from the top of the list starting with 1>

That is correct.  

To simplify things, first open a large xterm and do:

	iptables -t nat -L PortForwarding_3191 -n -v --line-numbers
	
and look up the rule number.  Then use:

	iptables -t nat -D PortForwarding_3191 <rule num>

Just make sure that you're deleting that from the startup scripts or
whatever it is that loads the rules when you reboot the machine.
