Hopspot with ips public addresses list.

Hi friends, I would like to make a hotspot with this configuration:

I have from my ISP 3 ranges of Public IPs with the same gateway, I would like that my hotspot give this public IP address to my clients. I have in this moment a patronsoft firstspot software that make this but the problem is that running under windows and its more inestable. In this software I have to disable NAT and active ARP PROXY and I give all mi IPS in a list of ARP PROXY that software have but In mikrotik I tried to do the same but I wan´t be abble to. I Try with one to one NAT but Its better to give directly public address to my clients if its possible with mikrotik.

Any idea? Thanks.
