IIS 7.5 - Exposing a website on a different port is not visible outside of localhost

Question

I have a Windows 2008 Web Server with IIS 7.5. There is a website on port 80 which I can hit using the IP address or domain name. I added another website on port 83, and if I navigate to localhost:83 on the server I can see the website just fine. But when trying to access the website using the IP address and port number I am getting a 404.

I have a feeling that I will need a DNS entry or some other settings to expose this site to the internets.

To reiterate:

• http://72.xxx.xxx/ resolves fine (port 80)
• http://72.xxx.xxx:80/ resolves fine (port 80)
• http://72.xxx.xxx:83/ does not resolve
• localhost/ resolves fine (port 80)
• localhost:80 resolves fine
• localhost:83 resolves fine (on the server only)

Obviously my binding is set to HTTP *83 with all IP address, same as the one on port 80

My end game is to make this a sub domain, which I know requires DNS, but I am hoping to just expose it using the port for now.

Any advice would be most appreciated.

Answer 1

I found the solution - I had to add a INBOUND rule to allow port 81 through the firewall. This is why I am a developer and not a system admin, though these days the line blurs.

Thanks for taking a look guys.
