After rebooting CentOS /etc/sysconfig/iptables changed
Hi,
I am using CentOS 5.9 and I have added port to make it accessible in a LAN but when I reboot the file /etc/sysconfig/iptables always changed to original one .
Kindly let me know how may I save my changes to these file so that it could not change by system reboot.
Thanks!

generally you wouldn't edit it, you'd add it in the live iptables config, and then use iptables-save to write it back to file.

on my CentOS 5.10 hosts, I run
Code:
/sbin/iptables-save > /root/safe.rules
and in /etc/rc.local I use
Code:
iptables-restore /root/safe.rules
How to get that to occur on restart|reboot, I don't know... |

oh, yes.... "/etc/init.d/iptables save" wraps the iptables-save command with the sysconfig file. that's what I'd forgotten.
