Azure internal load balancer outbound connectivity

Question

How can virtual machines behind an Azure internal load balancer access internet? Is there an AWS NAT gateway equivalent in Azure?

Answer 1

By default, Azure VM behind an Azure internal load balancer, that VM can access the internet, but you can't access it from internet.

If you want to access it, you can create a VM in that VM with a public IP address, use that VM work as jumpbox. Also you can assign a public IP address to that VM, then use that public IP address to access it.

Answer 2

A Virtual Machine that is part of the backend pool of a Standard (not Basic) Internal Load Balancer can not make outgoing connections to the Internet.

To make outgoing connections it is necessary to create a second Load Balancer with a public IP with the same backend pool and a dummy rule with a dummy probe. Once the rule is created then it will trigger the creation of an outbound SNAT.
