Just in case it is not  clear to whomever stumbles upon this,

The "config" file you need to "nano" is located inside this folder:

/var/lib/lxc/containername

nano config

The other file i believe is edited by nano from the root but I dont think it actually needs modification now....

nano /etc/network/interfaces

Im also glad I finally got it! 

Thank you Jeremy and all for your help and hard work!

Lets have more fun!
