Hi AprilYoho ,

 

This is a great article and is exactly what we are trying to accomplish.

 

A few questions:

 

  • In steps 8-10, it says that the loopback is created just by adding the secondary NIC with custom MAC address. Is this correct or did you also have to run a command to create the loopback after adding the secondary NIC (e.g., New-NetIPAddress -InterfaceAlias "Ethernet 2" -IPAddress 127.0.0.1 -PrefixLength 8)?
  • Does the secondary NIC need an IP address as well? We plan to point other VMs in the same subnet to this License Server, and am wondering if we can set a static IP on the secondary NIC and point them to that, instead of pointing them to the primary one.
  • How do we modify which NIC outgoing traffic is sent from? For example, if an external server needs to verify the MAC address, how do we send that traffic from NIC 2?

Thanks for the help 🙂
