This is definitely the way to allow both applications to run. I decided to be brave and install Pi-Hole on my existing Pi-Aware machine and all I did was run the curl installation for Pi-Hole, follow the bouncing ball to complete the install. Add the external.conf file to /etc/lightttpd directory with the following contents.
server.modules += (
"mod_alias"
)
Low and behold
192.168.xxx.xxx:8080 - Shows the Pi-Aware web page
192.168.xxx.xxx/admin - Shows the Pi-Hole Interface
