Okay i have a followed the tutorial perfect fedora core 3 setup. and installed ipsconfig. I want the ispconfig server also to be the primary dns server. in the ispconfig it lists the ip as the private network ip and gives room for other ips below. when creating a new site ( actually the www part of server1.example.com) so that www.example.com is an account) do i use the internal ip or external ip and do i add the external ip to the list and use it when setting up?
