multiple public addresses

Hey Paul, 

It's pretty tough to answer that exactly or with efficiency in mind without knowing the rest of your setup.  I'm taking a LOT of guesses 

I'm not too familiar with the 100D - but on my devices that I have all over the place I can assign a particular node with an external IP by creating an interface with the range that you have, then create objects for each external IP and map that to the VLAN.  That brings layer 2 to a layer 3 object and you can still use Application Sensors / IPS etc. 

Anyone can feel free to correct me if I'm wrong.  I know I have at least 1 endpoint configured directly with an external IP and from memory thats how I did it.  VLAN object -> Single IP Object within range on Interface -> ISP. 

I would also look to see if you can use NAT and internal addressing.  It'll probably save you headache down the road.  My $0.02 and I'm FULLY aware I'm still learning.
