I've created a website on IIS on my server, and can access this through my server to prove that the website is running fine locally.

I have set up these bindings on the site:

enter image description here

I've followed advice from other sites and stackoverlow itself to open port 90.

However, I still can't access this site externally outside the servers network using that IP address. Does anyone know why?

That IP address ( is a private IP address that is not available externally.

Depending on your network setup you will need one of the following:

  • Assign a different public IP address to that server
  • Set up port forwarding on your router
  • Set up a reverse proxy from some other web server on your network that is already publicly accessible

If you don't want the port number (:90) to be part of the URL, you should change the server to run on the default ports: 80 for HTTP and 443 for HTTPS.

  • Thank you for answering, this may be a dumb question but how do I assign a public IP to the server? Is it something that can be acheivable through server manager?

    You would have to connect that server to a different router, different port on the router, or modify your routing tables. What type of network do you have with what types of routers? Nov 30, 2021 at 14:18
