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 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'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've changed RDP port to 8080 in registry on my Azure Virtual Machine (Windows Server). Now it is not accessible from outside, I cant connect it.
Azure VM is managed by Resource Manager (not Classic VM).
UPDATE:
Turning secuiruty rules so allow all not helped.
I've changed RDP port to 8080 in registry on my Azure Virtual Machine
(Windows Server)
We can use CustomScriptextension to check if RDP listening on port 8080.
netstat -ant | findstr "8080"
If your port not listening on Port 8080, we may need to restart RDP service.
If RDP listening on port 8080, we can use CustomScriptextension to disable windows firewall.
netsh advfirewall set allprofiles state off
About Extension, we create a ps1 file with the command, and upload it via Azure portal.
Azure has to know to allow traffic through to your VM. By default, on a Windows VM, only RDP is open. But you (for some reason) changed the RDP port in Windows Server. You need to do this with the network interface as well, via the VM settings (which has nothing to do with Windows itself):
Via Settings, go to Network Interfaces
Select your network interface and go to Network Security Group
From network security group, add an inbound rule for port 8080 (or modify the existing RDP rule to be port 8080).
It used to be possible to change your RDP port in Classic portal using endpoints. but in RM portal you cannot change your RDP port.
If you are trying to secure your box or by pass the security firewall to connect to your box, I recommend using Azure Load Balancer NAT rules, you can create a NAT rule to translate a custom port to 3389, and then you can only allow connectivity from LB to your VM, this a trick I use when I want to by pass the corporate's firewall, for example port 443.
Make sure you attach the LB to your VM from the NAT rule section
To access any port from public ip client -
Enable port in Azure firewall (if installed)
Enable Port in Network Security Group (add inbound rule) rule like 8080 -> 8080 or rule like 80 -> 8080
Enable Port in Windows Firewall of VM (on azure) -- most important if port is other than 80 and 443. - e.g. 8080, 8090 etc..
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.
