For what is the Network/Zone Configuration?

It have those options:

NIC Assignment

GREEN/RED: Default/Bridge/MacVTap
each interface : Native/None/VLAN

any help in this?

Be carefull with this config because you can lockout from WebGui if you misconfigure the network.

Default is only one Nic in the zone. Bridge is to add more than one Nic to a zone. (act as switch)
If you not know what vlan (need vlan switches) or MacVTap (for libvirt addon) is don’t use it.

Thanks for the reply.
