Thanks for being here! I loved your introduction and your reason for
using Ubuntu :)

Are you using an actual bridge (combining eth0 and eth1 to form a br0),
or are you refering to bridging as just getting access to the rest of
your home network from your laptop?  If you are indeed using bridging, I
recommend you don't do that and give the card that goes to your laptop
an IP address on another subnet. You can then "share" your connection to
the rest of your home network by sharing the connections from your home
network card to the card that goes to your laptop. The forum page on
http://ubuntuforums.org/showthread.php?t=91370 briefly describes it.
Your current setup may already be similar but would just need tweaking.
It would be helpful if you could paste the /etc/network/interfaces file
from your desktop machine.
