I happned to check one server configuration which is in our office. The note poin is Firewall rules (iptables) are not in /etc/sysconfig/iptables instead the rules are stored in /usr/local/admin/etc/firewall/iptables_rules.dflt

How can it be done? Which way we can do this? Is it source compilation?

OS is CentOS release 4.3 (Final)

Please give me more info
