Hi,

May you check that? "Reinitialize the MAC address of all network cards"

It is a feature that virtual box has. Is necessary for some VMX Juniper VCP VFP.

Hi Mike, thanks for reply:

I had a VMX setup with internal image and as you can see below due the duplicate mac-address I can't setup a topology using these images. I could changed the mac address by configuration, but the without mac reinitialize the hardware is the same, the local-link ipv6 is the same etc, and there will be problem to build topology.
