I am trying to host a web service on aws ec2 windows server 2008 r2 instance, but am unable to access the server using its public ip outside the instance. The port my application is hosted on as 3333. I have added rules for SSH, HTTP and ICMP in my security group but still cannot access it externally.
I can connect to the machine via RDP but cannot even ping the ip from my local machine. Is it something not supported on amazon free 12 month account?
Have been struggling with this for a while, any help appreciated. Below attached is the snapshot for my selected security group for the instance.
Thanks,
Aakash
You can access your server from anywhere even if you have free tier. You just need to add correct inbound rules in the associated security group. In your case, rules seem fine but the windows defender must be blocking all the incoming requests. You can try turning off the windows defender in your windows ec2 instance by searching "Windows Defender Firewall" -> click "Turn windows defender firewall on or off" -> select "Turn off windows defender firewall(not recommended)" for public requests.
I was facing the same issue. Turning it off worked for me.
I has nothing to do with free tier. You need to allow the ports which you want to access from public. Please go to security groups and allow it.
Make sure that you have allow your server to public access.For giving access go to security group in that inbound rule and allow them to public access.

Following a how-to book's guide on setting up a VM through the Azure Portal and getting the error when trying to connect
Remote Desktop can't connect to the remote computer for one of these reasons: 1) Remote access to the service is not enabled 2) The remote computer is turned off [Verified through the Azure Portal it is turned on because Start is faded, while Restart and Stop are not] 3) The remote computer is not available on the network.
The error occurs before I'm able to enter any credentials - it doesn't find the IP at all. The RDP file details (IP removed of course):
full address:s:[IPAddress]:3389
prompt for credentials:i:1
administrative session:i:1
What I've tried:
Even though the How-To book doesn't show where/how to specify a port, when I download the RDP file from the Connect option, it specifies the port 3389. The book seems to imply that simply downloading this file and connecting will work and there's no need to specify the port. I get the above error.
Flushed DNS on my computer, ipconfig /flushdns
In the Network Security Group option for the VM, I verified that port 3389 allowed any source and wasn't specific.
I did miss associating the subnet part of the Network Security Group to a virtual network, so I did associate my NSG with the default subnet set up for my Virtual Network.
From the Quick start option, I don't see how to connect to this either; I'm guessing, I need to specify a different port, but don't see where to do it here either => Update: this appears to be in the Network Security Group's Inbound security rules in the Azure portal.
Boot Diagnostics option shows the login screen. A ping to the IP address fails four times with "Request timed out."
Note: this is not a Virtual Machine (classic).
just wanted to share what worked for me.
After receiving an error prompt:
Connect is disabled for this virtual machine because of the following
issues: Network interface 'vmwindows1094': Network security group
'VMWindows10-nsg' does not have inbound security rule that allows port
3389. VMWindows10-nsg
I have added an inbound port rule. Under VM > Settings > Add inbound port rules.
Port: 3389 Protocol/Source/Destination: Any (this can be configured based on your security rules) Action: Allow
On the Azure portal, Select your VM -> Settings -> Boot diagnostics. Make sure that you can see the login screen. You might need to enable diagnostics (under Monitoring section) if not enabled already.
If you don't see the login screen, trying the 'Redeploy' option under 'Support and Troubleshooting' section of settings.
If you can see that the machines has booted correctly, the connectivity issue might be because of a firewall at your end or on the VM. See if you can ping the machine. If you are behind a corporate firewall, try connecting from elsewhere and check your PC's firewall.
Creating a new Virtual Machine on the new portal now creates a NSG (Network Security Group) along with the VM. You should be able to find it under all resources, same name as you VM. Make sure that there is an Inbound rule configured for Remote desktop (it is created by default but might be worth checking).
I had the same problem but adding an inbound security rule was not sufficient (although it is also needed).
I had to go to virtual machines > (myVm) > Reset password and then choose Reset configuration only
Try checking your VM has enough memory.
I had tried all of above suggestions and still didn't manage to access.
After trying many times I managed to get in a message appeared saying:
Your Computer is low on memory
Not 100% sure that was the reason though.
I faced the same issue. I had created an Azure VM but wasn't able to connect to it using RDP.
The culprit was a default "Inbound Port Rule" due to which all the inbound traffic was being blocked.
The solution is to create a new rule by clicking the "Add Inbound Port Rule" and allow traffic from port 3389. Make sure that the priority of this new rule is greater than the "DenyAllInBound" rule otherwise our new rule will not have any effect.
After adding the rule, try connecting to the VM using its public IP in RDP and you should be able to connect.
This worked for me, hope it helps you as well.
I am trying out the Free Trial Microsoft Azure.
Basically I created an VM running Windows Server 2008 SP1.
There, I am running GeoServer, being able to access the geoserver from the local browser (eg: http://localhost:8080/geoserver/web)
Now, how to access this from a public browser? It has a public IP 13.93.154.109
which I can't even ping it, not to say to access it.
What did I miss out?
Note: I tried both classic/non-classic VM, result is the same.
Also, I am aware that there is an OpenGeo Suite out there for Azure. But it costs a lot. What I am trying to do is, to share the VM with the other existing product.
Thanks in advance.
localhost-from-vm
P.S: I am able to ping 13.93.154.109:3389 using PsPing instead of normal Ping.
You need to open the port 8080 to allow traffic on your VM.
Depending on how you have created the VM, it can be done in different ways:
If you have used the Classic workflow, you need to add an endpoint to your cloud service: https://azure.microsoft.com/en-us/documentation/articles/virtual-machines-windows-classic-setup-endpoints/
If you have used the Azure Resource Manager workflow, you need to create an inbound rule in the network security group: https://azure.microsoft.com/en-us/documentation/articles/virtual-networks-create-nsg-arm-pportal/#create-rules-in-an-existing-nsg
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'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.
Cheers
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.
My Azure web role can, using remote desktop, connect with a browser (IE) to google.com and to a DMZ server on our corporate network.
My web role cannot connect via HTTP GET (IE) to a non-DMZ box behind the firewall. My web role cannot ping this box either. My service is hosted in north/central, allegedly all published IP ranges of north/central have been granted access to the target IP by our CorpIT people. They claim they are seeing no traffic via their sniffer from my compute instance IP when I attempt to ping or HTTP GET against the target local IP.
CorpIT wants help from the Microsoft side but we have no Microsoft relationship. I'm convinced this is the outcome of months of slapdash thirdhand firewall rules applied to the target environment in question. What can I do to further elucidate this for CorpIT?
thx in advance!
You can try to run a trace route or get a network trace from the Azure instance and see what you get back from where. You could also create a support case with microsoft:
https://support.microsoft.com/oas/default.aspx?&c1=501&gprid=14928&&st=1&wfxredirect=1&sd=gn
I wouldn't bet on using the IP ranges to make your applications work correctly. Windows Azure already provides you with some services that allow you to solve these types of issues:
Windows Azure Connect: Allows you to create an IPSec secured connection between your servers and your hosted services. This means you won't need to add rules to the firewall for incoming traffic.
Windows Azure Service Bus Relay: Allows you to expose WCF services to the cloud without having to add rules to the firewall for incoming traffic. Choosing this option might add some extra work for you to do, you might need to create a WCF service if you don't already have one and change the code in your Web Role to connect to this WCF Service.
