I would appreciate for someone to assist me with the following DNS questions! Basically I own 1 domain. I have a static IP on a cable modem. I have setup Ubuntu 6.06 + ISPConfig (latest version). My goal is the following. I wish to host 3- web sites from my cable connection for now. Low-bandwith requirements, thus this should be good for now. At the same time I wish to learn from this experience and get familiar with the entire setup for a co-location setup in the future. I have attempted to read multiple articles regarding the DNS configuration. I just cannot grasp the fundamentals of how it all works. At this point and time, I own 1 domain and have 2 clients that own their own domains as well. I have 1 static public IP provided by my ISP. I went to my registrar which is Internic.ca and removed their 2 Name Servers; I replaced them with my Internet IP. Tus my Internet IP is now there for primary and secondary, and if I understand correctly this should work but simply not provide me with any redundancy. Yesterday during Trial, I had this somewhat working in a VM. When I would place www.mydomain.com it would give me the index.html of that site that I made under ISPConfig. Port fowarded is DNS, Web, etc.. from my router to the ISPConfig server which has a IP Address of 192.168.2.8 If I would go in browser and place http://myipaddress it would show me a ISPConfig page that would state that this IP is shared... and to use a domain name or such. From what I understood was that ISPConfig somewhat looks at the incoming request and then uses the Symlink of that request for the proper web directory... Now today, I re-installed everything on a physical PC because I was having issues with Flash, and I was considering that something was not properly configured on my end. Now when I digg my domain it shows me the IP internal IP of 192.168.2.8 .... I think that I messed up because when I created the site today on a fresh install; I choose the options Create DNS and Create DNS MX; which I had not done before... now nothing works... I am accessing this from a completely different PC on the internet thus no loopback problem as a possibility... It seems that when I put http://www.mydomain.com from this PC, that Internic, my registrar sends/converts the request to my Internet IP, which forwards that request to my ISPConfig Box, which then messes-up and shows a 192.168.2.8 which is the internal NAT ip... Can anyone explain to me in very simple terms if what I am trying to do is possible? Meaning that I only have 1 server or want 1 server which has Ubuntu 6.06 + ISPConfig and I want to serve and manage a small quantity of web sites... Any help will be GREATLY appreciated! Thanks in advance.
