I have a Virtualbox VM set up with two interfaces. One is a bridged NIC, the other is a wireless USB, connected to using the USB addon. They are both setup at boot using DHCP. Whenever either one is active the address for either interface is responded to. (i.e. eth0 UP only - ping to IP of eth0 responded to & ping to IP of wlan0 responded to & vice versa) Now if both interfaces are down then no responses are given.
Is this a design to enable fault tolerance or anything?
Also (on a somewhat related question) In the "Networking" sectio of the "Adavnced Menu" on the "Show this adapters's IP address in Usage" what is that referring to? Is it talking about where it shows you the server addresses?
