How to edit iptables

[DanglingChap]

Hi,

I want to change the already written script of iptables and reflect the new changes. the step i am following are as ..

services iptables stop

This stop the iptables. and then i open the script file that has been written by some senior person and is placed at the following location

/etc/rc.d/rc.firewall

after adding the extra ip's .. i restar the iptables

services iptables start

Ideally, i should have been able to connect to the server through new IP's but i am still unable to. when i check the iptables status using this command

services iptables status

I don't see any changes that i made (i.e no new ip table in accept). How would i make the changes in iptables?




P.s:
I have already read this tutorial iptables-save but this seems not working for me since we are using a script file.

You didn't tell use what distro you are using.
Not every distro work the same so...

I am willing to be that service iptables start isn't reading from the script you have modified.
The above normally reads from a saved file the rules that are applied to the firewall unless this script iptables has been modified to read another file.

If you want to use this rc.firewall script then you should run that not service iptables start.

It is as simple as '/<path>/<script>'
As long as the permissions are set correctly.

i ran the following commands on the server

service iptables stop
service iptables start /etc/rc.d/rc.firewall

and then i tried this command to check if the new ip's are in ACCEPT list

iptables -nv -L

but no new ip are being shown

service iptables stop
/etc/rc.d/rc.firewall
service iptables save
