[SOLVED] Policies are gone after rebooting.

hi
i was trying to use iptables for blocking sites. it did work, but after the reboot the policies were gone! i didn't find anywhere saying that the policies were temporary, so i guess something else is wrong, can anyone help.
i used the following policy:

Code:

iptables -A OUTPUT -d www.somesite.com -j REJECT

Thanks,

Hello,

I believe that whatever you execute with regards to iptables is for the running session. You need to use the commands

Code:

iptables-save
iptables-restore

Check out these links:
Here on LQ
Or for example here

Kind regards,

Eric

That is absolutely right.
All your rules have to go to file, which firewall reading when it is starting up.
For example, in opensuse 11.1 there is a file in:
/etc/sysconfig/scripts/SuSEfirewall2-custom - for the custom rules.
This location is describe in /etc/sysconfig/SuSEfirewall2 - main config for firewall

In your system should be something the same. Read man page.

thank you everybody, it now works. i added the rules in a script and made the script to run at startup.
