It doesn't save the firewall, even with "service iptables save," so when the server is rebooted or if anyone does "service network restart," the iptables rules are somehow flushed and we have to run the firewall script again manually. We're running a pretty stock K12LTSP 4.2.1. Kernel-2.6.10 Does anyone have an idea as to what could be going wrong?

Right now I am on an Ubuntu box so cannot trace the command but man for something like "chkconfig". The command is something like "chkconfig --level 35 iptables" Alternatively run "setup" as root and in services enable the iptables as service. This will make it run at boot time. </pre> </blockquote> rightly said, 1) check wether it is enabled for run level in which you are running your server. "chkconfig --level 35 iptables" OR for temp solution do "service iptables start/restart" 2) could check the status "service iptables status" 3) save your settings as iptables-save > your_iptable_rules 4) check wether " /etc/sysconfig/iptables" exists, if yes make a backup of it. now put your rules as "iptables-restore < your_iptable_rules" can also use "service iptables save" at last i would suggest you to see "/etc/init.d/iptables" script. hope this will help a bit. regards, Bimal Pandit </body> </html>
