I have created a VMSS with a load balancer (LB).
Now there is only one VM with a nodeJs application running in and listening on port 80.
I have allowed port access on VM Firewall (inbound + outbound).
I have added an Inbound LB NAT rules on port 80 through the portal. However after saving, it does not show up.
Now I could not access my application with the Public IP or DNS name.
What is wrong with my approach ?
How can I do this with the portal or the powershell ?
I would not like to recreate the scale set.
Finally make it works through the portal. In fact the scale set has an Inbound NAT Rule and a load balancing rules. Allowing firewall port access and NAT rules are Ok for this scenario but not enough , a Load balancing rule on port 80 needs to be added. Before the load balancing rule is added a probe should be added first.
In short here are the steps:
Firewall access on port 80
Inbound NAT Rule (under load balancer) access on port 80
Probe access on port 80
Load balancing rule on port 80 (need a probe)

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.

I have setup a few VM's and a load balancer so that we can have one outgoing IP. Right now i am having issues to connect to the internet from inside my VM. If i open internet explorer and try to access a website, it shows waiting for reply and then "This page can’t be displayed".
Each VM is connected to the same subnet.
The subnet has a NSG attached to it and each VM is part of the subnet.
NSG attached to the subnet.
There is then a load balancer to allow incoming RDP but with different ports to the different VM's.
I think i am missing the SNAT but i have no idea where to configure that. From what i have read, i am using level 2 "Public Load Balancer associated with a VM (no Instance Level Public IP address on the instance)". Multiple VM's on a subnet and one load balancer to share one IP address.
Where do i actually go to set up the SNAT? Or is there another issue i am missing here?
Probably, you could add the load balancing rules for TCP port 80 or 443 instead of inbound NAT rules. NAT rules always use for port forwarding. Moreover, you do not need add NAT rules for DNS. This works on my side.
A load balancer rule defines how traffic is distributed to the VMs. The rule defines the front-end IP configuration for incoming traffic, the back-end IP pool to receive the traffic, and the required source and destination ports.
Hi I have a azure vm on which I want to configure port forwarding so that I can redirect traffic to 1100 port, I have created a public loadbalancer and in NAT rule I have configured the ports, but seems that I cant RDP onto the VM using my port 1100, can anyone suggest me some documents where I can get this thing done?
Or point me in the right direction?
As I understand, you want to RDP your Azure VM through the front port 1100 of Load Balancer.
So you need to add your VM into the Backend pools of Load Balancer, and then create NAT rule to forward the traffic to your VM through port 1100 exposed to the internet.
The NAT rule setting panel will like this:
You can select your VM at which I frame up with the red pen if you added it to the Load Balancer backend pools. And you can set port as 1100 and target port as 3389 which RDP really used. When it's OK. You can connect your Azure VM through port 1100.
You can get more details with the document Create inbound NAT rules.
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 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.
