Do you have any > suggestion for installing the iptables? Then it's probably installed, which you can check with: rpm -q iptables Note that iptables is in /sbin. So, if you are changing to root, use su with a dash (-) to make sure that the PATH variable is updated: su - If not, you'll have to specify the full path to the iptables command. -- Daniel
