I've tried doing research on this question, but I've been unable to find information on this specific situation.
I have Virtualbox 4.2.6 running two hosts, a Debian machine running isc-dhcp-server, and the other a Ubuntu machine running hostapd. I wanted the Debian host to provide an IP address to both Ubuntu and to any user that tries to connect to my wireless network. But I can only get an IP address assigned to Ubuntu.
Btw, I'm not running the DHCP server on Ubuntu since I finally gave up on trying to remove/work with Apparmor. Also, I'm not running hostapd on my Debian host since it won't work with my AWUS036NH.
