Azure VM Behind LB No Internet

less than 1 minute read


So one of the first tasks we had to do in Azure is load balance some VMs. Since this was an internal LB, I assumed that VM’s would still have internet access but I was wrong.

To Resolve:

  1. If you place VM’s behind an internal LB with the Standard SKU, they will not have internet access. The only way is if you:

    • Give each VM a public IP address
    • Change the LB to a public LB
    • Move them to a NAT Gateway - see here
