I just upgrade my system (windows server 2003 host, linux guest) from v1.6 to v2.2.4. I previously used three NIC in my host, one for the LAN, one for the host internet, and one dedicated/bridged to the linux guest to be a public web server. With the changes in way VBox handles bridged network connections now, I was able to do everything I wanted with just two NIC instead. It made my life so much easier (no more routing table problems!).
The new network structure is effin' brilliant.
Thank You!
That is all.
