Understanding static MAC address licensing in Azure

Hi MarcinBB , we had 2 NICs. The second NIC was the one in which we assigned the static MAC address. The primary NIC was the one that Azure uses to communicate with the VM. To sum it up, all Azure networking, connectivity was through the primary NIC, we did not modify this MAC address. The second NIC is the one we used to assign the MAC address that the licensing server referenced. 

Effectively, the primary NIC was for Azure, the second NIC was for licensing, so the VM could still communicate using the primary NIC
