Thanks to All.
I understand too much from your posts but still i have some confusion. I am working on Aruba devices for 3G project and configure many Outdoor and Indoor AP's. What i was do, i just configure IP Address, Subnet Mask, Master Controller IP and Server IP directly on the AP. And then do little configuration from controller once my AP reached to Controller.
Now the confusion is what type of this configuration i do because i didn't configure any GRE or IPSec tunnel.
I Attached the scenrio of our network for your information.
