Hi everybody !!! I have seen a pair of iptables scripts in order to learn the technique and I noted that there's no a unique order in the construction of the ruleset. I'm new at this matter so I have to ask you this 2 short questions: 1) What option is the best: at first I set the default policies in the chains and later I flush all the existing firewall rules or viceversa ??? 2) Is it a good practice to start the iptables firewalling rules from the rc.local script or is it better from the /etc/init.d/iptables script ??? (I use RH 9 and I start iptables from rc.local) Thanks a lot, byeeeee Alejandro
