Even though I switched I needed to refresh my guest network adapter to pick up a new ip address, use the commmand ifconfig in the guest to find out what IP its using and set bbb-conf setip to that ip address result from ifconfig. The guest will use the host's adapter to get out to the web/network.
For a Putty connection, run this command on your guest: sudo apt-get install openssh-server
Run Putty with the ip from above (ifconfig result) with port 22.
