Azure connectivity problems

Question

I just created a virtual machine in Azure. I can connect to it without problems to access remote access, but it does not respond to my ping. I have the File and Printer Sharing (Echo Request - ICMPv4-In) rule enabled in the firewall and I don't understand why it doesn't answer me... I understand that there must be some problem with the configuration in Azure.

Can anybody help me ??

All the best

Answer 1

Hi Luis,

I understand you have allowed inbound traffic on the VM, however it is necessary to allow inbound traffic in Azure. Default rules block inbound ICMP.

To allow ICMP inbound, please navigate to the VM in Azure and perform the following.

On the left-hand navigation, select Networking

Select Add inbound port rule

Define your rule

Once added, test ICMP.

Hi @luis Miguel Perez lopez

By default, an Azure VM's network interface or the subnet it's connected to has an NSG that blocks all inbound ICMP traffic, including pings. Even if you have the File and Printer Sharing (Echo Request - ICMPv4-In) rule enabled in the Windows firewall, the Azure NSG might still block the pings.

Search for 'Network security groups' in your Azure Portal, or NSG linked to your subnet, go to 'Inbound security rules' and add ICMP form source any

The inbound ICMP Echo Request (used for pings) is usually allowed on the Windows Firewall by default, If you're not sure about this, check Windows Firewall inside VM

Thanks to both of you. The ping works for me. Now what I need is for it to work for port 8172. I have done the same steps to open port 8172 but it doesn't work...

telnet 1.1.1.1 3389 => it does work (RDP)

telnet 1.1.1.1 8172 => it does NOT work (MSDeploy)

I don't know what's going on
