I am trying to open a port in a Windows Azure virtual machine. I have a game listening on that port, and I am able to access it via localhost, so the game is running.
I have also opened the port in the firewall and created an endpoint in the virtual machine, but the port doesn't seem to be open to the outside world. I have tried accessing it both via the IP address and the DNS with the same results.
Is there anything else I should do? I have looked up several tutorials online and can't figure out what I am doing wrong.
this has changed to this
I would recommend ignoring 100% of what is on google at the moment
Irina, make sure you have configured your endpoint properly by setting the private and public port. Here's a documentation that explains the steps to accomplish this...
http://www.windowsazure.com/en-us/documentation/articles/virtual-machines-set-up-endpoints/
It's easy via Azure CLI, for example , open port 80
$ az vm open-port -g MyResourceGroup -n MyVm --port 80
Open multiple ports at the same time
az vm open-port -g MyResourceGroup -n MyVm --port 80-100 --priority 100
Open all..
az vm open-port -g MyResourceGroup -n MyVm --port '*'
Pay special attention to this parameter,Must be unique for each rule
--priority : Rule priority, between 100 (highest priority) and 4096 (lowest priority).
Must be unique for each rule in the collection. Default: 900.
This is a two step process:
Configure the port rule in the Azure Portal (No need of any restarts. The effect takes place in a few minutes.)
Here are the steps (at the time of writing): Click on the VM -> Click on 'Networking' -> Click 'Allow inbound port rule'
Configure the port rule in the VM's own Firewall - this depends on the Operating System your VM has got (OR disable this firewall)
Here are the steps for Windows 10:
Open 'Windows Firewall with Advanced Security' Desktop App -> Click on 'Inbound Rules' on the left panel -> Click on 'New Rule' in the Actions panel on the right. The following screenshots explain the rest.
Now the application listening to the port can be reached over the internet.
For future reference, if you're trying to listen to 3000 or that range it simply does not work.
Go to the 8080's range, make the inbound rule and you're up and running.
Probably this is the latest solution at a time of writing this answer:
You need to create a Network Security Group (or use an existing one). The easiest way is to search for Network Security Groups in the search resources bar. If there is an existing NSG, click on it and find inbound security rules from the settings. Then add an inbound rule with your desired port.For example, I opened port 8080 on my VM with settings shown in picture below.
More info: https://azure.microsoft.com/en-us/documentation/articles/virtual-machines-windows-nsg-quickstart-portal/
In addition to described, you may need to create inbound rule in VM firewall. The settings in portal create forwarding from public IP towards VM. VM itself should allow applications to listen on the port.
This may explain why this didn't work for Irina on some ports and worked on other ports.
Check the Windows firewall on the VM also. If port 8080 is not added in firewall inbound rules, then make sure to add a new inbound rule to allow access to port 8080. (Remotely login to your VM. Windows Defender Firewall -> Advanced Settings)
Source port ranges: * (allows any source port)
After you've created a VM that's configured to serve web requests on the standard TCP port 80, you can:
Create a network security group.
Create an inbound security rule allowing traffic and assign values to the following settings:
- Destination port ranges: 80
- Source port ranges: * (allows any source port)
- Priority value: Enter a value that is less than 65,500 and higher in
priority than the default catch-all deny inbound rule.
Associate the network security group with the VM network interface or subnet.
it's assumed you've already started the appropriate services and opened any OS firewall rules on the VM
for other example : port ranges: 2022-2023

The instance is running fine. I am using linux os and apache-tomcat-8.0.33 server. I can access from private ip using putty But when i am trying to access the same through the public ip, it is not accessible. I have seen the security configurations all ports are enabled.
Can anyone help me how to reslove this issue
inbound image
I faced the same issue recently; I was not able to access the website which I hosted on Ec2 server Via public IP.
Check 1:- the First step would check your AWS security group and make sure all the inbound traffic rules are fine.
Check 2:- Windows firewall can also play a role in disallowing the access via public IP. Create a new Rule for allowing access for HTTP and HTTPS ports (80,443).
Steps
a. Go to control panel -->Windows Firewall ---> Advanced Settings.
b. Select the Inbound rules from the left Menu.
c. Select New Rule from the Right panel.
d. Allow access to ports 80 and 443.
In my case, everything worked fine once I created a new rule in windows firewall under Inbound Rules.
You opened your amazon web console
You go to Amazon EC2 Security Groups
You should have a default group for inbound rules (see below)
You click on Modify inbound rules (modifier les règles entrantes in French here)
Once done, you add your public ip with the subnet you want
I've added my IP public address and you should be good.
Regardless of the number of ports open in your security group, if you must access your ec2 instance using it's public IP, over the internet, you must assign an internet gateway (IGW) to the subnet your ec2 instance belongs to
http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_Internet_Gateway.html
As you mentioned and others answers, you can find the problem by following this steps:
1- Try telnet to your server by public IP address on port 80, if it opens go to the next step, if not open you have two possible issues:
security group (Check your inbound rules)
web server settings (Check your web server settings and find why not listening on port 80)
2- If telnet was working, so you have not the connectivity issue, now track your web server access log by tail command and try open a page by the browser. If you see your request in the access log, but it does not return the correct value you expected, so you should check your web application.if you can't see your request, check your web server settings.
I'm trying to setup a Win2008R2 IIS webfarm on Google Compute Engine.
I've got the machine setup, however when I try to add it to a network load balancer pool, the balancer consistently reports the machine as unhealthy - even if i disable healt checks. I have a single forward rule setup for port 80.
I've tried different size instances in different regions/zones to no avail. Traffic into the load balancer never makes it to my instance, and the instance is always report as unhealthy.
For the firewall I went ahead and added a blanket rule so 0.0.0.0/0 can access all local net services (ICMP;TCP:1-65535; UDP:1-65535) and I've disabled windows firewall.
Anyone have any experience getting this working?
Spoke with google support. "Known issue with windows instances - check back in 6 months." In the mean time, use linux or setup your own NLB within your project.
Strange that it is not working for you. I replicated your situation and I am getting to the machine with no issues. The load balancer is forwarding traffic as expected and it reaches the system who is marked as healthy in the Lb pool.
You may want to add the following rule to the windows firewall with advanced security(make sure you use the "advanced security" one and not the default):
Inbound rule > New port > port 80
Once this is done, from your machine you can curl or telnet to the address while running a netstat on the Windows system and you should see the LB forwarding rule IP making requests :
$ curl IP (locally)
$ netstat (on the windows machine)
Hope this helps !
This seems like it should be beyond simple, so I hate asking. But I've tried to configure Windows Firewall to allow XDebug to connect to PHPStorm on port 9000 without success.
XDebug is on on Vagrant Box with private network connection--so the host machine has a virtual network adapter. Vagrant is 192.168.33.10 and the host PC is 192.168.33.1.
With Windows Firewall disabled, XDebug connects to PHPStorm. But I obviously don't want to leave my firewall off.
So I've tried to open a port in Windows Firewall with the following Inbound Rule settings:
General
Enabled: Check
Action: Allow the connection
Program and Services
All programs that meet the specified conditions: Checked
Services
Apply to all programs and services: Checked
Protocols and ports
Protocol type: TCP
Local port: Specific Ports : 9000
Remote port : All Ports
Scope
Local IP address
Any IP address: checked
Remote IP address
Any IP address: checked
Advanced
Profiles
Domain: checked
Private: checked
Public: checked
Interface types
All interface types: checked
Edge traversal: Block edge traversal
But it's not working to allow XDebug to connect to PHP storm. I've also tried setting the protocol to UDP. And I'm aware that if this rule did work, it would be excessively open (I could tighten up the scope), but for the moment I just want to see it work before tightening it.
There is a problem with Virtualbox network host-only interface since it is loopback interface and Windows manage it in a diffrent way.
Easy way to solve this is to open 'regedit'. Search for 'HKLM:\system\CurrentControlSet\control\class{4D36E972-E325-11CE-BFC1-08002BE10318}'. There is plenty of interfaces. Simply look one named 'VirtualBox Host-Only Ethernet Adapter'. Then add new DWORD(32) key named '*NdisDeviceType' and value '1' (hex). Reboot.
I don't know if there is a need to add standard fw rules like host port 9000 allow for all, since i had it already.
More about it - http://brianreiter.org/2010/09/18/fix-virtualbox-host-only-network-adapter-creates-a-virtual-public-network-connection-that-causes-windows-to-disable-services/
The simplest approach that I found: Windows Advanced Firewall (where you add/remove rules) -> right-click -> Properties (another place for en/disabling Local/Domain/Public firewalling)
Each off the three scopes (Local/Domain/Public) has a setting to exclude firewall-processing for specific network interfaces completely (!)
Turn of windows firewall for any vmware/virtualbox network interface. (unless you require it against your virtual machine)
This will allow any connection from your guest, to your host machine.
In general, it's easier to not specify rules in terms of protocols or port ranges. Rather, just let the the program executable have a firewall exception for everything. So instead of creating a rule for port 9000, just create a rule for "xdebug.exe", but don't limit it to just port 9000.
Control Panel->Windows Firewall -> click "Allow an app or feature through Windows Firewall", then add xdebug.exe (or whatever the executable name is). This will add a new set of inbound rules (one for UDP and another for TCP). Go back to the advanced settings page, find the new inbound rules that were created, and inspect each to validate thatl the "Scope" checkboxes are set (private, domain, public).
There's a way to turn on firewall logging so you can discover what is getting blocked when the firewall is on. Then you can add rules as appropriate.
http://technet.microsoft.com/en-us/library/cc787462(v=ws.10).aspx
If you have a NAT adapter on your box in addition to virtual adapter, you can change xdebug config in php.ini xdebug.remote_host parameter to the IP of physical interface on your machine. Easiest way to find out is to try to telnet to 9000 port.
I am having trouble connecting to an Amazon Elastic Cloud Computer Instance via a browser.
I attempted going to ********.compute-1.amazonaws.com , but the browser returns that the connection has timed out.
I can connect via ssh and winscp. That is how I uploaded a web app I developer. I have also created a security group and added rules to open ports 22 and 80.
Do I have to assign the security group to the instance somehow?
The security group's rules also do not have a source IP, well they do its 0.0.0.0/0
I would really appreciate any and all help in getting this site ' viewable ' via a browser.
By default, your instances will only be in the default security group. If it's an EC2 instance you cannot change security groups while the instance is running, you'll have to specify them in advance. If it's a VPC instance you can change security groups at runtime.
Add the rule to the default group
You can however add the rule to allow port 80 to that default security group; just don't create a new security group as it can not be associated with the running instance.
Is the web server up?
Also, make sure that your web server is up and running. From your instance (using SSH shell access), check if the right process is listening on port 80, using the command netstat -lnp. You should then see a row with proto tcp and a Local Address ending in :80. The IP Address listed should be either 0.0.0.0 (meaning 'any IP') or a specific IP of a listening network interface.
Web server not up
If you are in need of a web server, take a look at Apache or Nginx. They both support PHP.
Hope this helps.
I had also faced similar issue with ec2 micro instance. I was using Red-Hat AMI. Despite of opening ports 8081 in security group, I was not able to a telnet to the host port. Disabling the iptable did the trick for me:
sudo /etc/init.d/iptables stop
Do not forget to disable firewall if you use windows for your server.
I faced the same issue while setting up redash AMI image on AWS. Inbound security rules should be changed when instance is not running. Let's say if the instance is running (meaning it's active and started); If you change the inbound rules of that machine you'll still face firewall issue. So Stop the machine on which you want to change the inbound rules on. Change the inbound rules. Start the machine now. Now you can hit the machine url from the ip you just opened the access to the machine to.
The EC2 instance firewall is maybe enabled.
Check it with this command:
sudo systemctl status firewalld
if enabled you can disable it with :
sudo systemctl disable firewalld
or setup rules to allow port 80 trafic
I have a rackspace cloud server running windows server 2008 r2. I've uninstalled IIS because I want to install Apache.
I've installed Apache but it fails everytime i try to run it when i listen to port 80.
I've run the command netstat -aon|finderstr "80" and i see the following:
C:\Users\Administrator>netstat -aon|findstr "80"
TCP 0.0.0.0:80 0.0.0.0:0 LISTENING 4
TCP 10.180.15.249:139 0.0.0.0:0 LISTENING 4
TCP [::]:80 [::]:0 LISTENING 4
UDP 10.180.15.249:137 : 4
UDP 10.180.15.249:138 : 4
So what are these things running on port 80 and why can't i get apache to start? Is there an alternative port for to run apache under that will work just as well as 80?
To enable port 80 on Windows Server 2008 R2:
NOTE: This assumes that IIS is not installed. I added this firewall rule to enable Apache to accept connections on port 80.
Click Start->Control Panel->Windows Firewall
Click "Advanced Settings" in the left panel of Windows Firewall
Click "Inbound rules" in the left panel of Advanced Settings
Click "New Rule..." in right "Actions" panel
Select "Port" and click "Next>"
Select "TCP", then "Specific local ports:" (should already be selected)
Type 80 in the box (just the number) and click "Next>"
Select "Allow the connection" and click "Next>"
Leave all profiles checked and click "Next>"
Enter a name and click "Finish".
Your server should now be able to accept connections on port 80.
On a Windows server running MSSQL, disabling MSSQL ReportServer (display name: SQL Server Reporting Services (MSSQLSERVER)) services and World Wide Web Publishing services, resolved the problem for me. No need to fiddle with firewall settings or changing default port configurations.
I am running a windows 2008 r2 with IIS and sql server. I added an additional IP address to run apache and configured IIS to bind to one of the IP addresses. I ran into the same problem and found suggestions about disabling SQL reporting services and WinRM. These solutions did not work for me.
There are many different services that can use the http server api(http.sys) and will then show up simply as pid 4.
I found the answer at the link below. The essence of the link is to go to a command prompt.
Type netsh press enter.
Type http and press enter.
add iplisten ipaddress=x.x.x.x
http://msdn.microsoft.com/en-us/library/cc307219(v=vs.85).aspx
There is also a method to disable http.sys in the registry but I do not know what the ramifications of that might be.
I hope this helps someone else so they don't waste as much time as I did trying to find the resolution.
I find that I can successfully add the firewall rules to make my own server run on port 80 within the vshost visual studio debug environment but when running as a service it only works on local host from the machine and not from external hosts.
Very frustrating. Seems that there are possible conditions in the firewall which are not exposed in the Windows Firewall configuration interface very clearly.
With IIS installed you need to change bindings on web sites in IIS so that none uses "all available addresses":80 binding. Either change the ports, or change listening IP addresses.
