I have an Azure VM, and a web application listening internally on port 32001. The VM is publicly accessible on a static IP address. I'm trying to route all traffic the VM receives on port 443 to its localhost port 32001. I am try to set it up in this screen, and my first idea was to edit the HTTPS rule. But no matter what I try, I can't seem to get a connection to my webapp. What am I supposed to do?
You can't do this using just VM. What you actually need is a Load Balancer in front of your Azure VM which takes care on port forwarding. An example you can find here and here. But in short, what you need to do is:
expose 32001 on your VM
create Load Balancer
add VM to backend pool in Load Balancer
configure port forwarding on this balancer
In inbound and outband rules you can configure what traffic is allowed, but you can't configure there port forwarding.

So I'm using an Azure VM that has a public IP address, and I've opened an inbound port, let's say it's 5555.
What I'm trying to do now is to run an application on the VM that has an API via localhost, also with the port 5555. I'm calling it then with public_ip:5555/api/...
Since I was not able to connect to the application from outside, is there something missing here? Most tutorials and resources I've found just mentioned opening the port.
Thanks.
Take a look at Azure's IP Flow Verify utility, which will check your NSG rules to ensure traffic can reach your VM. https://learn.microsoft.com/en-us/azure/network-watcher/network-watcher-ip-flow-verify-overview
If traffic is reaching your VM, check your host firewall and then your application server logs.
I have a flask server hosted on my azure vm.
if __name__ == '__main__':
app.run(debug=True, host="127.0.0.1", port=4400)
On vm, I can access the server via the address 127.0.0.1:4400
Now I want to be able to access this server from outside the vm i.e. my local computer.
I have already added the inbound security rule as below:
I have also added the same inbound rule on the VM's firewall on port 4400
Still I am unable to access the flask server via publicIP:4400 (publicIP is the public IP of my VM as displayed on the azure portal)
What could be the issue?
For your issue, there are two possible reasons.
You must listen to the IP 0.0.0.0 so that it's possible to access from the Internet. The 127.0.0.1 is just a loopback IP for the test in the localhost. So 4c74356b41 is right in this way.
If you also cannot access the app from the Internet when you change the IP into 0.0.0.0. Then it must be the rules issue. You should check your VM networking if it's the same NSG for your subnet and NIC. If not, add the rule to allow the port 4400 in both NSGs. Then you also should check if the public IP is associated directly with your VM, or it's associated with the load balancer and your VM is just in the backend of the load balancer. If it's a load balancer, you still need to add the load balancer rule to allow the port 4400.
Take a check for the two possible reasons.
I have IIS Installed on Azure VM with one Website running on PORT 80 which is exposed over the internet via the following Azure Firewall Role
if I try to bind incoming traffic on any other port that is not PORT 80, for some reason the Firewall doesn't seem to allow it.
for Example, if have a website running on PORT 8080 and I try to Set Firewall roles from EXTERNAL IP to the Internal IP via PORT 8080... the Website is unreachable.
If the website runs on PORT 80 and the Firewall Role is via PORT 80.. than the site works.
does anyone have any idea/suggestions?
I would like to be able to Expose websites over the internet from the Same Web Server using different PORT for each one.
I've found the answer to my problem via this URL:
https://manage.accuwebhosting.com/knowledgebase/2886/How-to-configure-IIS-to-access-website-using-IP-address.html
Basically After create Inbound Firewall Role from Azure on port 8080, the next step is to Add in Windows Firewall a New Role to allow Incoming HTTP traffic via port 8080 or any other port that the Wibsite is binding.
hope this will help others.
I need to configure incoming https traffic(443) onto port 8443 (tomcat).
I have following Inbound security rules:
However, open port check for port 443 from http://www.yougetsignal.com/tools/open-ports/ fails.
I have verified that tomcat is running on port 8443. What could be the possible issue?
It is possible in Classic Virtual Machine. In Resource Manager mode you need to create load balancer and create NAT Rules.
Deploy a sample load balancer from: https://azure.microsoft.com/en-us/documentation/templates/101-loadbalancer-with-nat-rule/
You might get the idea from it.
I am using Azure Virtual Machine (Windows Server 2008 R2 image) provided from the gallery and created Public port and private port using the portal. I did remote log in to VM and I run a TCP server application inside VM (TCP server binds to the private port of the VM). Problem I face is that I can not connect it through the public IP and port (from external machine). I have created a inbound rule in VM's Firewall, where I enable connection to the Private port of VM. I tried recreating the VM, also the new ports. Still problem persists. One more thing I observed is that my TCP Client is able to connect to RemoteDesktop port of the VM also the PowerShell port. But does not connect to the port that I created through the portal. Pls suggest what can be wrong?
Note: I also observed some weird behavior. I enabled all ports for my TCP Server app in Inbound rule of firewall and found that some unknown IP (was similar to azure internal IP) is connecting to my server. Why it is happening?
I would like to understand as to how you are trying to connect with the Virtual Machine, using RDP or trying to test the connectivity, for example, using Port Ping.
Endpoints for RDP and Powershell are configured by default. So if you are trying to connect using Remote Desktop, you can directly connect to the VM using MSTSC from Run and provide the IP of the VM followed by the Port Number using the below format
xx.xx.xx.xx:3389
However if you would like to test the connectivity to the VM, I suggest you to use Port Ping instead of ICMP ping since ICMP traffic is blocked by the Azure load balancer and the ping requests timeout. While Ping.exe uses ICMP, other tools such as PsPing, Nmap, or Telnet allow you to test connectivity to a specific TCP port.
On the other hand, after creating the VM, you can add endpoints additionally as needed. You can also manage incoming traffic to the public port by configuring rules for the Network Access Control List (ACL) of the endpoint.
The private port is used internally by the virtual machine to listen for traffic on that endpoint.
The public port is used by the Azure load balancer to communicate with the virtual machine from
external resources. After you create an endpoint, you can use the network access control list
(ACL) to define rules that help isolate and control the incoming traffic on the public port. For
more information, see About Network Access Control Lists.
