by

Step 1: Add Inbound Rule of Windows Firewall

  1. Open the Windows Firewall with Advanced Security.
  2. At the left panel, right click on Inbound Rule > New Rule
  3. Rule Type: Port
    Protocol and Ports: TCP
    Specific local ports: 57976
    Action: Allow the connection
    Profile: Tick all (Domain, Private, Public)
    Name: Name, Description(optional)
  4. Finish.

Step 2: IIS or IIS Express

Add Bindings of IIS Manager

  1. Open the IIS Manager.
  2. At the left panel, Go to Sites > Default Web Sites.
  3. At the right panel, click on the Bindings. Then, the new dialog pop ups.
  4. At the pop-up dialog, click on the “Add” buttons. Input the port number and the hostname.
    For my case,
    port = 57976;
    hostname = 192.XXX.XXX.XXX (my IP address)

Add Bindings of IIS Express (Visual Studio)

  1. Stop the current Site
  2. For Visual Studio 2015, change the IIS config under your project folder C:\Projects\<ProjectName>\.vs\config\applicationhost.config‌​.
  3. For previous version of Visual Studio 2015, change the IIS config under IIS Express folder C:\Users\<your profile name>\Documents\IISExpress\config\applicationhost.config
  4. In applicationhost.config, search by the port number (for my case is 57976), then one more binding with your IP Address
    <site name="Web(1)" id="9"> <application path="/" applicationPool="Clr4IntegratedAppPool"> <virtualDirectory path="/" physicalPath="E:\abc\project\dev\web" /> </application> <bindings> <binding protocol="http" bindingInformation="*:57976:localhost" /> <binding protocol="http" bindingInformation="*:57976:192.XXX.X.XXX" /> </bindings> </site>

Updated:

For windows 10 or Visual Studio 2015 users, you may get the error message below:

Unable to launch the IIS Express Web server, Failed to register URL, Access is denied

Solution:
