Settings for iptables does not persist

[Holmes.Sherlock]

I have installed iptables on the Core platform & have set up persistence successfully. But, I can't find where iptables specific settings are stored. So, all the rules I am adding are getting flushed on next reboot. Please help.

You can do something like this:

Code: [Select]

$ touch mymarker
[do whatever causes the settings to be stored]
$ sudo find / -not -type 'd' -cnewer mymarker | grep -v "\/proc\/" | grep -v "^\/sys\/" | tee files
$ vi files
This probably requires the findutils extension

This seems quite dreadful set of commands to me. Can you please explain what these try to achieve?

This will make a list of all files created after the "touch mymarker" command and thus will tell you where the iptables rules are stored.

I see, quite roundabout a way.

If you manually type them, they are not stored anywhere. Merely made active in the kernel.

Yes, I need to use iptables-save & iptables-restore

Those commands work on stdout and stdin, so where the results are stored is up to you

I will store them in persistent storage & load back using startup script.
