Virtual network interface

NethServer Version: 7
Module: Network

is there any opportunity to add a virtual green network interface? If i add it via the console the shorewall will not start. It says that virtual network interfaces are not supportet. I want to change the one real interface to red.

Thanks in advance for your help.

Hi Ben,
is nethserver installed at a virtual mashine? If so, you could give a second network-card at the virtual manager. Then nethserver thinks it has two “real” network-cards.
But perhaps somebody else has a better idea.
