NAT and PUBLIC IP

Hello Forum,
I have a question about NAT and PUBLIC IP’s. I do configure mySM’s using the two IP’s, i use the Public IP’s 192.168.0.x and NAT with 172.16.x.x but now i want to use BAM and i have just one IP which is the 172.16. x.x that the BAM server gives me to configure my SM’s , i had been thinking on how to do the configuration with just one IP or am I going to use the 172.16.x.x to configure the SM’s as the WAN side and use 10.X.X.X to NAT the SM.
I will like to have advice or solutions on how to configure as i will be switching my old clients to the BAM in the coming days.
Please i need solutions
thanks in advance
