hi all,
I have a problem with iptables on CentOS 6.2. I configured:
chkconfig iptables on and the file /etc/sysconfig/iptables
if you reboot the machine configurations are not loaded. iptables-L gives me the default configurations (not assigned) if I (a machine booted): service iptables start then then it works.
how can I fix? thanks in advance

After service iptables start do:
service iptables save
This saves your configuration for the next restart / reboot

ChriG, thank you for your help I solved the problem but until now it had never happened with the VPS. iptables first started out and then edit the file /etc/sysconfig/iptables and chkconfig iptables on
good to know many thanks

sorry, but now if I modify /etc/sysconfig/iptables and I add two strings, per example:
output omitted ----- -A INPUT -s ddns.no-ip.org -p icmp -j ACCEPT -A INPUT -j DROP ------ output omitted
and I do:
service iptables save and restart my iptables firewall, output iptables -L is:
-A INPUT -j DROP -A INPUT -s ddns.no-ip.org -p icmp -j ACCEPT
why?

'service iptables save' tells iptables to take what's running in iptables RIGHT NOW and save it to that file. so your added lines got overwritten. so what previous replies have been expecting you to do is boot up login as root start doing your commands e.g. iptables -I INPUT -s 192.168.0.0/16 -I eth0 -j DROP get all the iptables command entries set to how you want them, check with iptables -L then run 'service iptabels save' and reboot just to be sure all your rules got saved and are restored after a boot. (although it shouldn't technically be required)

When you do # service iptables save it over-writes /etc/sysconfig/iptables with the active set of iptables, so your changes are lost. One way to do what you want is to modify /etc/sysconfig/iptables, then do # service iptables restart This will reload the iptables from /etc/sysconfig/iptables
