Would that be "Bridged Networking" in V-box?  I found this reference in 
the manual, but am not sure it this is the same thing you were talking 


With bridged networking, VirtualBox uses a device driver on your /host/ 
system that filters data from your physical network adapter. This driver 
is therefore called a "net filter" driver. This allows VirtualBox to 
intercept data from the physical network and inject data into it, 
effectively creating a new network interface in software. When a guest 
is using such a new software interface, it looks to the host system as 
though the guest were physically connected to the interface using a 
network cable: the host can send data to the guest through that 
interface and receive data from it. This means that you can set up 
routing or bridging between the guest and the rest of your network.

For this to work, VirtualBox needs a device driver on your host system. 
The way bridged networking works has been completely rewritten with 
VirtualBox 2.0 and 2.1, depending on the host operating system. From the 
user perspective, the main difference is that complex configuration is 
no longer necessary on any of the supported host operating systems^"
