I have created a CentOS 7.1 VM using Resource Manager deployment model.
I am not able to access the application using a browser on a machine connected to internet.
However I am able to access the application on same machine and other VM on same virtual network using private IP address.
I configured Network Security Group and allowed port 80 and 443 in Inbound Rules.
Well, it turned out that I needed to open ports under "Inbound Security Rules" and needed to open all in "Source Port Range". For doing so, i needed to put * there and in Destination port for https - 443 etc.
This * thing was the catch which i was missing in all the Inbound security rules for allowing the ports.

I have created a Windows WCF Service and I want to host it inside Azure VM.
The service is locally running fine inside the VM, but when attempting to access the service outside of the VM, I cannot connect to the service at the specified port.
While requesting the service, I'm getting the following error:
SocketException (0x274d): No connection could be made because the target machine actively refused it...
Also, while pinging the VM through the command prompt with public ip, I'm getting Request timed out.
I have enabled the port for TCP in Azure inbound rules as well as in VM firewall inbound rules. The VM is Windows Server.
How can I access the service running in the VM from another system?
Any help is appreciated.
check application is running on the port you exposed
check windows level firewall allows traffic on that port from your destination
check NIC level NSG allows traffic on that port from your destination
check subnet level NSG allows traffic on that port from your destination
you might also have Azure Firewall\UDR\NVA in the networking setup, check those as well (this is highly unlikely if you are not running an enterprise grade setup).
I've setup a VM and installed IIS. I checked that the firewall rules were enabled for HTTP and HTTPS. Furthermore, in Azure Portal, I've enabled the two predefined inbound security network group rules for HTTP and HTTPS.
When in the VM, I can go to localhost and see the default Web page of IIS Default Web Site.
Inbound security rule in Network Security Group
Anybody know how to go about figuring out how to make this work?
Thx
You should add port 443 and port 80 to azure VM windows firewall inbound rules.
Are the Source port ranges on your inbound rules set to 80/443 or * (i.e. all source ports)?
Try changing them to * with only the destination ports set to 80 or 443 respectively.
Ex:
Refer How to open ports to a virtual machine with the Azure portal for more details.
There are two ways to make your site accessible from the Internet.
Use the public IP address which is associated to the virtual machine's NIC.
Configure DNS for your VM machine (e.g. web.southeastasia.cloudapp.azure.com). This DNS is bounded to the associated public IP Address.
Reference: https://learn.microsoft.com/en-us/azure/virtual-machines/windows/portal-create-fqdn
In your IIS, just configure binding to make sure the incoming request from the Internet is recognized by IIS.
You also need to make sure you have no rule in Network Security Group (NSG) blocking port 80. Or if there is a NSG, you need to create an inbound rule to allow port 80.
I Azure Windows VM, apart from configuring the NSG rule, we should also create a Windows firewall rule to allow inbound TCP connections on the required port. Just RDP into your windows VM, open Windows Defender Firewall and add the rule
I have a Windows Server 2012 virtual machine provisioned on Azure. I installed Neo4j server on this virtual machine and I'm accessing the Neo4j browser on localhost:7474.
However I cannot access the browser outside using my virtual machine's public IP e.g <machineIP:7474>
Here's what I have done so far:
In the Azure portal, I added inbound rules for the NSG to allow http and https ports 80 and 443 (I have done the same on a Linux virtual machine also hosted in Azure and I can access the browser just fine)
I also added an inbound rule in Windows Firewall to allow Port 80 and 443 as well
What possibly blocks me from accessing the virtual machine's IP from the outside?
You have to add TCP port 7474 to the firewall in the Azure portal:
change your neo4j-server.properties
set
org.neo4j.server.webserver.address=0.0.0.0
To remotely access Neo4j installed on a Windows VM in Azure, these are the changes you'll need to make:
In the Azure portal, add TCP port 7474 to the Endpoints of your Windows VM
On your Windows VM, in the Windows Firewall Advances Security, add a new Inbound Rule for port 7474
Change the conf/neo4j.conf and uncomment this line:
org.neo4j.server.webserver.address=0.0.0.0
Note: In case you also want full access to Neo4j's browse interface including Bolt, then also add port 7687 both in the Azure Endpoints and the Windows Firewall.
I have a Virtual Machine created in the new azure portal (portal.azure.com)
Now I can connect to by using the Remote Desktop by the port 3389, without any problems.
I am asking for a guide to setting my virtual machine can be remoted over the port 443 also (since the working network just allows outcoming 443 only)
With the classic portal, I just need to add an "end point" and that works.
However with the new portal, in the "network security group", I tried to modify the "inbound security rules", changed the default value 3389 to 443, but I got no luck.
Edited: captured screenshots
New VM created as "Azure Resource Manager" (ARM) have different options and features but they lost end-points. Endpoints, in classic deployment, allowed to remap internal ports to external ports, changing the value.
Now, in ARM, to have a similar behaviour, you have to use LoadBalancer. Read at the end of https://blogs.msdn.microsoft.com/mast/2016/02/04/azure-networking-public-ip-addresses-in-classic-vs-arm/ for an example to map external 50000 to internal 80.
As I understand them, Network Security Groups don't actually do any port mapping, just allow/deny access to certain ports. If you want the RDP server to still listen on 3389 and for external RDP requests to go to 443, you'll need to use Azure Load Balancer with NAT rules (https://azure.microsoft.com/en-us/documentation/articles/load-balancer-get-started-internet-arm-ps/#create-lb-rules-nat-rules-a-probe-and-a-load-balancer). Alternatively, you could configure your RDP server to listen on port 443. It's up to you which you prefer :).
I just created a new Ubuntu 14.04 virtual machine in Microsoft Azure using the (recommended) resource manager deployment model. The following screenshots show the deployment configuration and the resulting resources:
Once it was deployed, I accessed the VM using SSH through the public IP, logged in and installed nginx. I left it with the default configuration and did a 'curl localhost' to ensure the webserver was running.
Then I went to the Network Security Group resource and added an Allow rule for port 80 to the Inbound rules:
I then opened a browser and tried to request the public IP associated with the NIC and got a connection timeout.
Edit: I can get access by disassociating the NSG from the NIC, but if I re-associate it, I will get blocked again within a few minutes.
I have tried using the same process to set up a Windows Server VM, with IIS, but I'm getting the same result.
What am I missing here?
I get no errors when doing the same setup using the classic deployment model, this only occurs when trying the recommended resource manager model.
For the ones that still struggle with the inbound rules on the new Portal Azure, you need to set up the Network Security Group (NSG) to:
allow connections from (source):
any sources
and
* - for the source port range (extremely important as it may seem normal to set 80 or 443 - which is not correct)
destination:
any
and
80 - as the destination port range (or the port that your webserver is listening to - it could be also 8080 or other)
The same goes for other ports like the 443 for the https connections.
What is your source port on your NSG? Did you leave it Any/*? If not you are limiting yourself to traffic coming only from that one port.
