In regards to the article about setting-up Fedora 7 as "The Perfect Server," I had a few questions (http://www.howtoforge.com/perfect_server_fedora7). 1. Does ISPConfig use iptables as its' firewall engine? I would like to have /etc/sysconfig/iptables like previous Fedora setups because it is what I am used to. 2. I am not sure the purpose of creating eth0:0 as a virtual interface. Is it something specifically for ISPConfig? I did not see where you used it. Thanks!
