I installed IIS on my machine (laptop), and added an new application.
All works fine, but I need to be display my application just locally and prevent browsing it from other machines.
Is that possible? If so, how?
The are several ways to achieve this, but the simplest solution is to block incoming requests using a firewall.
I suppose you use the default Windows Firewall and your web application is listening on the TCP port 80. So open an administration interface (command wf.msc), select "Inbound rules", locate the rule "World Wide Web Services (HTTP Traffic-in)" and disable this rule.
Other ways to achieve the same result:
Using the "IP Address and Domain Restrictions" IIS module with appropriate rules for requests filtering
Modifying site's bindings in IIS (set IP address for example to 127.0.0.1)

For a pet project I'm attempting to spin up a VM on Azure that can run as my webserver, providing an Umbraco powered site, as well as some other web applications (such as a forum + planner) that require PHP. Now I've followed the steps of every guide out there, but I cannot get an external connection through to the VM's IIS and I can't find out why.
I'm hoping someone else has been through the pain that I'm currently experiencing and might point me in the direction of whatever setting I'm missing.
Spun up the VM with Server 2012 R2.
Configured it to run IIS.
Installed Umbraco, disabling the default web site and setting the Umbraco site as my default on port 80.
Checked that http://localhost maps to Umbraco - this works.
So after I had it running internally, I started tackling the external connection setup.
Navigated to the Network Security group, and added the inbound Http rule on Port 80.
Disabled Windows Firewall entirely for the sake of testing.
Added a custom dns name to the front of the xxx.[azurecloudappurl].com
Now my requests resolve but then timeout and I can't see why or where? Has anyone else experienced this? Every guide states that it should be as easy as this.
As you can visit localhost on your VM env, so it seems there is no problem with your env on VM.
Have you added the endpoint with 80 port of your VM server on Azure manage portal? As by default, the endpoint with 80 port is not opened.
You can refer to How to set up endpoints on a classic Azure virtual machine for how to add an endpoint on Azure VM.
In addition to #Gary Liu's answer if you are doing it on Azure Portal(and not on classic one).
For any new VM added through Azure exists a Network Security Group (NSG). Ports need to be opened in order to make them accessible from outside the VM. Specifically to allow your VM to serve requests coming to port 80 you need to enable HTTP port in Network Security Group. Here are the steps:
Search for VM Name on Azure portal.
Select the VM by Clicking on VM Name.
Click on Network Interfaces from left menu and select(double click) the listed one. This will show overview of Network Interface.
Now click on Network Security Group.
Click on Inbound Rules.
Add new rule selecting service as HTTP(TCP/80).
Voila done!
And here is the answer to manage an inbound rule
I have create new web site in IIS 8. I have configured my web site like this
http://ip:8080/
When I browse it from any public network it is not opening. But If I open is locally it works fine. http://localhost:8080 it is working fine. What I tried I stop all other sites, Default Web site and assign 80 port to my site then it is working fine in locally as well as publically. I don't know what is the issue.
Clearly you have a firewall or other network routing issue. Check all configured firewalls on your server/housing machine, as well as along your network path (router, or other perimeter network devices)
Also if trying to connect through your internet side IP you will want to check any port forward rules on your router (If behind NAT, like most connections are)
My problem is solved. I have opened a 8080 port on Azure management portal. And on VM I have create new rule which points to this port.
I've just set up a windows azure VM and installed IIS on it.
When I remote desktop onto the box I can see the default IIS website fine but I can't get this to serve on the web from the IP address of the box.
I've opened up port 80 on windows firewall and also added an endpoint for port 80.
I've tried to access it with the firewall completely turned off also but to no avail...
I cant work out if there is anything else I need to do to get this working?
Add endpoints for port 80 (http) and port 443 (https) to the VM in the Azure portal (tip: this can be automated with powershell or the Azure cli).
Remote desktop to the machine. Open the Windows firewall control panel and allow traffic to port 80 (http) and port 443 (https) or just turn it off ... the firewall is ON by default (tip: can also be scripted through the VM agent / powershell).
Go to the Azure portal and find the cloudapp.net subdomain for your VM (actually the cloud service) your VM is running under. Try accessing the site with that domain. If that doesn't work, try browsing to http://localhost on the server (remote desktop) to make sure IIS works and troubleshoot from there.
Modify the DNS records of your custom domain to use a CNAME to the .cloudapp.net domain. If you need A records make sure to use the public IP of the cloud service (just ping the .cloudapp.net domain to find it or look in the Azure portal).
You might want to look into Azure Websites or Azure Cloud Services (web roles). Those are a lot easier to manage and a lot cheaper. They still offer most of the functionality.
What fixed the issue for me was to go into the Azure Portal, browse to 'Network Security Groups', select the VM and then create an inbound rule to allow traffic to port 80.
Note: Also ensure that the inbound rule to port 80 is added and enabled on the actual VM.
Well, I deleted the existing VM and Cloud service and started again - all worked fine out of the box this time.
How annoying! The only thing I did notice was that before my cloud service had the same name as my VM - this time they had different names so that might have been what was causing the issue.

For the newer VMs and pre-configured setups (2015+), it's possible your setup is using an azure asset called "Public IP". If so, you can set a custom DNS name label in it, inside "Configuration". Note that this name will consider any type of region used when creating the VM (e.g. my-site.brazilsouth.cloudapp.azure.com).
It's good to remember that for testing purposes, it still suffices to use the value of the public IP that is randomly designated to you.
The VMs are actually accessed via a Cloud Service (well they are for me). Azure created a Cloud Service automatically to be the scaling engine/load balancer on the front of the VM. I have to connect to the web site via that cloud service, not the VM directly.
Its possible you were using the internal IP rather than the external IP.
The sites have to use the internal IP address in the bindings section of IIS. However, in your dns you will need to use the external IP. This is presumably since the 'internal IP' is just a virtual one that Azure uses to map traffic from the external network to the VM's inside azure.
You should find both the internal and external IP's are visible on the VM's desktop.
Switch off TLS 1.3 in the Registry Editor.
This is what worked for me as of writing this in Mar 2021.
I have just created an azure virtual server 2012 and made a simple html page.
I installed IIS on it, and added an endpoint to my portal, called it web and set it to tsp, 80, 80, no load balanced.
But when I try to go to my domain, I get an error saying page not available.
I can login to my virtual server and run the page inside. So it works.
But it's blocking outside access.
There is also a firewall rule on the server allowing incoming traffic on port 80.
I am probably missing a step somewhere, but I could not find any instructions on how to do it. It is mostly guess work on my side.
Can anyone help?
Most probably you have forgotten to allow port 80 for incoming connection on the local Firewall of your Windows Server.
UPDATE
Have you correctly mapped "your domain" to the couldapp.net domain of the VM instance? Or are you using the yourname.cloudapp.net directly?
I can't connect to the default web site in IIS 6.0 using localhost or 127.0.0.1 or by server name. When I telnet to port 80 with one of these names, there's no connection.
However other web sites are running and I can telnet using any of the ip addresses.
I can ping to localhost where 127.0.0.1 is responding.
The default web site is running. It's not stopped.
check the windows firewall, that has a habit of blocking IIS on a local machine
Is the default site bound to a specific IP address? By default it would display "all unassigned" for the IP, but if you've linked all sites to a specific IP address, then the local IP would no longer be configured on the server and would not answer.
httpcfg.exe did it.
Stop all the sites under IIS, restart IIS and start the one you're interested in.
If this fails delete all the sites under IIS and create from scratch. If this fails, the problem is not with IIS and you'll need to look at what other services are running and start turning them off.
A firewall may prevent some content of your website/website itself from being accessible, so if you have problems with accessing content then check that your firewall is not rejecting content from your site.
The easiest way to ensure that your firewall is not blocking your access to your site services is to use your firewall control panel to allow data from *.(your site url).
