Don't know about Debian, and I haven't actually tried FreeBSD as a guest in
VirtualBox, but have used it for other things.
The default install of vbox sets up a logical NAT/DHCP server internally, so
all you would do is use vi to put something like ifconfig_rl0="DHCP" in
your /etc/rc.conf. Substitute the according vbox interface. When you
configure your new VM in the OSE the default NIC type will be PCnet-FAST
III (Am79C973) in vbox 2.0.4. This is supported by the pcn driver so your
line would be ifconfig_pcn0="DHCP".
IF you get the interface to come up examine it with ifconfig -a. I believe
vbox settles for a 10.0.2.0/24 network, but YMMV. You may need to play
around with defaultrouter="something" and name services in resolv.conf or
fiddle with dhclient.conf. The best is to ensure that dhclient.conf is
pulling the info from DHCP rather than trying to manually stuff numbers in
Also, if the pcn driver doesn't seem to want to play and if you are using
VirtualBox 2.0.4 there are 2 Intel Nics you can try (not sure if they
are "Windows" exclusive, or not - will find out in the next few days as I
plan on trying Nexenta this way) instead which are supported by the "em"
driver (ifconfig_em0="DHCP"). This just has to match whatever you set up in
