Internet for VM without a Public IP

Question

Hello,

I have a VM running on Azure. It does not have a Public IP. I am accessing the VM via VPN (Site-to-Site, On-Premises to Azure Virtual Network Gateway).

How can I allow the VM to access the internet? The NSG associated with the VMs NIC/Subnet has the default Internet Outbound rule.

I'm quite new to Azure.

Thanks in advance

Hi @Kiran Kumar K S ,

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.
I understand that you would like to understand more about outbound internet access from an Azure VM.

You should be able to access internet just fine from the VM though it does not have a public IP.
The outbound internet connections will use a random IP belonging to Azure. (This IP might change depending upon availability)

This is documented here : https://learn.microsoft.com/en-us/azure/virtual-network/ip-services/default-outbound-access

P.S : Note that this is not recommended for production workloads.

Kindly feel free to let us know should you require additional information

Cheers,
Kapil

Answer 2

Hi @Kiran Kumar K S ,

if you are running an Azure VM without an explicit public IP the default outbound access IP is used for internet access from the VM.
https://learn.microsoft.com/en-us/azure/virtual-network/ip-services/default-outbound-access

By default the outbound internet access of a VM isn't limited and you should be able to access the internet from the VM.

Thanks for the reply anonymous user-MSFT & @Andreas Baumgarten .

I had actually come across the article.

It's actually my mistake. I had checked only Ping from my Linux VM to the internet. It's disabled by Azure for some reason?

nping worked and I've now verified internet access.

Thanks again.
