Thanks a lot for your response Bingo. I think I will need to do so more 
research before I deploy the local zone server as SN's. Like you pointed out I 
will have to go through the installation guide couple of time to get a better 
understanding. I was wondering if anyone had ever used this kind of 
configuration before.

I am glad to know that I could have multiple AFTD devices (just as I though 
of). We are running NW power edition so I guess I should have no restriction 
from the NW Version perspective and I am good from the licensing side as well.

Regards,

Jango
