Viewing my IIS hosted site on other machines on my network

As others said your Firewall needs to be configured to accept incoming calls on TCP Port 80.

in win 7+ (easy wizardry way)

1. go to windows firewall with advance security
2. Inbound Rules -> Action -> New Rule
3. select Predefined radio button and then select the last item - World Wide Web Services(HTTP)
4. click next and leave the next steps as they are (allow the connection)

• Because outbound traffic(from server to outside world) is allowed by default .it means for example http responses that web server is sending back to outside users and requests

• But inbound traffic (originating from outside world to the server) is blocked by default like the user web requests originating from their browser which cannot reach the web server by default and you must open it.

You can also take a closer look at inbound and outbound rules at this page

First of all, try to connect to the LAN IP of your server. If IIS is set up with only one web site, chances are that your site is going to pop up.

If you want to access it by name, you would have to add an entry in the HOSTS file of every client PC you want to view the site with (not to 127.0.0.1 obviously, but to the local IP address of your server).

Also, your Firewall needs to be configured to accept incoming calls on Port 80.

This is usually the point where it makes more sense to set up a DNS service that you can register names like "mysite.dev" with centrally, without having to dabble with hosts files. But that's a different story, and belongs to superuser.com or serverfault.com.

In addition to modifying your firewall, don't forget to add port binding too!

Open $(SolutionDir)\.vs\config\applicationHost.config and find binding definitions, should be something like this

<sites>
    <site name="Samples.Html5.Web" id="1">
        <application path="/" applicationPool="Clr4IntegratedAppPool">
            <virtualDirectory path="/" physicalPath="C:\Git\Samples.Html5.Web" />
        </application>
        <bindings>
            <binding protocol="http" bindingInformation="*:63000:localhost" />
        </bindings>
    </site>
    ...
</sites>

Just add extra lines to reflect your machine IP and designated port

<bindings>
    <binding protocol="http" bindingInformation="*:63000:localhost" />
    <binding protocol="http" bindingInformation="*:63000:10.0.0.201" />
</bindings>

It might be late, but for any other person who may get such an issue in future, for any connections you want to make to the server (in this case the machine that hosts the web application, regardless if it is iis or xampp) you need to allow connection or traffic through the specific port that will be used in the firewall

1. Go to Windows Firewall -> Advanced settings
2. Click Inbound Rules -> Then New Rule
3. Select Port -> Next
4. Specific local ports -> Add the Port you want to allow
5. Allow All Connections
6. Enter a name and a description for to help you remember later on

and you Done

127.0.0.1 always points to localhost. On your home network you should have an IP address assigned by your internet router (dsl/cablemodem/whatever). You need to bind your website to this address. You should then be able to use the machine name to get to the website, but I would recommend actually editing the hosts file of the client computer in question to point a specific name at that computer. The hosts file can be found at c:\windows\system32\drivers\etc\hosts (use notepad) and the entry would look like:

192.168.1.1     mycomputername

Full worked solution on 2021.

The binding with IP is not worked. The asterisk solved the problem.

<bindings>
   <binding protocol="http" bindingInformation="*:63000:localhost" />
   <binding protocol="http" bindingInformation="*:63000:*" />
</bindings>
