HOWTO VirtualBox Host networking
http://ubuntuforums.org/showthread.php?t=346185&page=3
Turn off the host firewall until you have host/guest communication working.
br0 usually gets the IP address your eth0 had. Give your guest an IP address
one number up from tap0, then use the same default gateway your host uses.
I have this working on OpenSuse 10.2 host, but haven't figured out the
required SuseFirewall2 forwarding/routing rules required.

first, just to make sure it isn't in use). The "user" in the first command is
the user you login with.
Code:
sudo tunctl -t tap0 -u user
sudo chmod 666 /dev/net/tun
sudo /usr/sbin/brctl addbr br0
sudo /sbin/ifconfig eth0 0.0.0.0 promisc
sudo /usr/sbin/brctl addif br0 eth0
sudo /sbin/dhclient br0
sudo /usr/sbin/brctl addif br0 tap0
sudo ifconfig tap0 192.168.0.94 up
sudo bash -c 'echo 1 > /proc/sys/net/ipv4/conf/tap0/proxy_arp'
sudo route add -host 192.168.0.45 dev tap0
sudo arp -Ds 192.168.0.45 eth0 pub
Those first 7 commands are from the help.ubuntu.com page I listed above (bottom
of that page.. long page.. but good!). The rest of the commands are actually in
the man page for 'tunctl' (man tunctl at a prompt). I just stumbled on them
because the first 7 commands alone were NOT doing it for me (Dapper).

OK, I got it partially working.
1. Get tunctl utility:
http://prdownloads.sourceforge.net/user-mode-linux/uml_utilities_20040406.tar.bz2
http://user-mode-linux.sourceforge.net/dl-sf.html
http://user-mode-linux.sourceforge.net/networking.html#daemons
tunctl -t tap0 -u [tux]
ifconfig tap0 192.168.0.210 up
brctl addbr br0
brctl addif br0 eth0 tap0
dhcpcd br0
ifconfig br0 up
The only problem is that bridging works to outside world, but not
between Host and Guest.
Can someone help me out with this ?
