Run multiple sites from one IP in IIS

Question

I have a box with Windows Server 2008 and IIS 7, and I'm using an ASP.NET app. I am trying to run multiple sites from one IP, but I can't access the sites from the outside. I can only access the Default website from outside but when I want to access the second one it does not work.

The second one should run on the http://ip:81 and the default one is on 80. They both run fine locally on the box and I have added a rule on the firewall to allow all inbound.

Answer 1

You can use the same port 80 for all the sites. It's all about the bindings. You need to bind each site to a different host name:

www.domain.com
site2.domain.com
www.anotherdomain.com

etc.

You can do this by specifying the binding when creating a site. Then make sure you have configured DNS records to point at the same IP.

You can also setup a catchall DNS entry for a domain and point it at the IP of the server, then every time you create a site you can simply pick a new subdomain name at it will work straight away.
