Do I need Iptables, Lokkit Firewall and APF same time?

Submitted by Anonymous on Tue, 04/14/2009 - 22:44

Hello, I am a linux beginner. Why are three firewall software(iptables, apf, lokkit) installed on a dedicated server? Do I really need all of them? Is not there a conflict related big risk. For example they could block each other and all other network programms and connections. I just want to have an easy to use and secure webserver with less limit.
