Configuring domain controller, DNS, IIS in Windows 2003
Posted on 2004-08-30
This is a question about my specific setup and a general question to help me learn about networking. Here is my setup.
I have a cable modem with a static IP (IP 18.104.22.168, Subnet 255.255.255.252, Gateway 22.214.171.124, DNS 126.96.36.199 and 188.8.131.52)
I have a Linksys wireless router (WRT54G) behind the cable modem (192.168.1.1).
I have four computers connected to the router and my VOIP box. 1 desktop (XP Pro, cabled, 192.168.1.20), 1 server(2003, cabled, 192.168.1.10), two laptops (both XP Pro, both wireless, 192.168.1.30 and 192.168.1.31) and the VOIP box (192.168.1.40).
On the server I need to setup a website that is visible internally and externally. The desktop and two laptops also have IIS installed for development and need to be visible internally only and addressable by name (not just IP).
I have setup the internet side of the router with the settings in the second paragraph above. I have setup the router, computers and VOIP box on my side of the router with the static IP addresses listed above. I have installed the domain controller, DNS and IIS on my server. The firewall is on on the router I have opend port 80 to my server (192.168.1.10). When I installed the domain controller/DNS it changed the preferred DNS on the server to 127.0.0.1.
My questions are, what are the correct TCP/IP settings for my 4 computers and why can't I see my website externally? I'm confused mainly about which IP to use for the DNS for the four computers and why I can't see my website externally but I can see it internally. And what is the 127.0.0.1 in the preferred DNS field on the server?
