Answer 1

Hi Arun,

In the Network Security Group that applies to the VM, did you create inbound port rule that Allow ICMP? If not, please navigate to the VM in the portal, Network settings blade, and click Create port rule - Inbound port rule button. Select ICMP and click Save.

Inside of the VM, did you enable ICMP Echo in the firewall? For windows, you would open wf.msc and right-click on Inbound rule File and Printer Sharing (Echo Request - ICMPv4-In) and choose Enable Rule.

Please click Accept Answer and upvote if the above was helpful.

Thanks.

Hello Arunkumar Venkatesan

Welcome to Microsoft Q&A Platform, thanks for posting your query here.

By default, outbound ICMP traffic is blocked on Azure virtual machines (VMs). In windows vm you have to allow inbound firewall ICMP port or disable firewall.

• Configure the Network Security Group (NSG) to allow ICMP traffic
• Set up the operating system to answer to Ping/ICMP echo request, configure the Windows Firewall.
